iOS From 1,99 To 1.99
Greetings! This is simple I'm sure and I'm just missing the proper class to do it. I need to convert a string representation from Canadian local to US Local. 1,99 to 1.99 The model is a float called quantity. From that model I pick up the value and display a localized representation of that float value into a UITextField (1,99) to allow user to edit the value, when the user is done updating the value I need to pick up the string from the text field and update the model. self.model.quantity = [self.numberTextView.text floatValue]; Only return 1.00 which is not correct. NSLocale *locale = [[NSLocale alloc]initWithLocaleIdentifier:@en_US]; NSNumberFormatter *formatter = [[NSNumberFormatter alloc]init]; [formatter setLocale:locale]; [formatter setNumberStyle:NSNumberFormatterDecimalStyle]; NSNumber *number = [formatter numberFromString:self.numberTextView.text]; NSString *numberString = [[NSString stringWithFormat:@%.2f, [number floatValue] ]; NSLog(@%@,numberString); Returns 0.00, even worst!!

Re: iOS Core Data complex predicate.
Andreas First off, thank you for taking the time to read my essay. I did not know the setReturnDistinctResults: was dependant on setPropertiesToFetch: your explanation is outstanding. That did the trick, and I thank you very much. Sandro. On 2011-03-17, at 6:49 PM, Andreas Grosam wrote: On Mar 17, 2011, at 8:15 PM, Sandro Noël wrote: Greetings!

About setReturnsDistinctResults: If YES, the request returns only distinct values for the *fields specified by propertiesToFetch*. That is, setReturnDistinctResults: makes only sense IFF you also specified the set of properties you want to fetch (via -setPropertiesToFetch). And this requires that you specify NSDictionaryResultType for the resultType property of the fetch request. As a result, with setReturnDistinctResults:YES you get a set of dictionaries whose values are distinct. In other words, you cannot use -setReturnsDistinctResults:YES to make your result set distinct if this array contains *managed objects*. You might use a NSSet which you initialize from your original array of managed objects in order to get a unique set. Alternatively, you might fetch just objectID properties using a NSDictionaryResultType. This, however, is a bit elaborated: When you return (unique) dictionaries as objects in your result array, and if you want these dictionaries having a key objectID which value corresponds the actual managed object of this dictionary instance, you need to create an appropriate NSExpressionDescription: and include this property description in the array which you pass to -setPropertiesToFetch: NSExpressionDescription* objectIdDescription = [[NSExpressionDescription alloc] init]; [objectIdDescription setExpression:[NSExpression expressionForEvaluatedObject]]; [objectIdDescription setExpressionResultType:NSObjectIDAttributeType]; Note: NSExpressionDescription is subclassed from NSPropertyDescription. Then you use objectIdDescription as one of the properties (NSPropertyDescription) you want to fetch: [myFetchRequest setPropertiesToFetch:[NSArray arrayWithObject: objectIdDescription]]; Don't forget to set the result type (after you set the entity): [myFetchRequest setResultType: NSDictionaryResultType]; [myFetchRequest setReturnsDistinctResults:YES]; ... The next step would be to extract the objectIDs from the array of dictionaries and store them in an array for convenience.

iOS Core Data complex predicate.
Greetings!
I am facing a problem with a complicated predicate I'm building.
it keeps returning multiple instances of the same records.
if every predicate used alone works as a charm, problems occur when they are
combined together.
my model is constructed as so
Table 1 contains most descriptive fields.
name
description
additional information.
Table 2 contains the categories
name for the category
keyword
Table 3 contains elements
name of the element
keyword
table 1 has a to-many relationship to table 2
table 2 has a to many inverse relationship to table 1
table 1 has a to-many relationship to table 3
table 3 has a to many inverse relationship to table 1
-one item from table 1 can belong to many categories and one category can be
assigned to multiple items from table 1
-one item from table 1 can have many elements, and one element can belong to
many items of table 1;
My search criteria's are as so.
user can enter keywords to search the tiems.
user can select from a list of categories the categories to search for.
user can select fro ma list of elements the elements to include in the search.
The keywords are separated in components and filtered against a StopWord array
as to keep only the relevant words to build the predicate.
each keyword is OR'd against three search field.
and then AND together as to assure all keywords appear in one particular item
of table 1
if ([self.searchText.text length] 0){
NSArray * components = [self.searchText.text
componentsSeparatedByString:@ ];
for (NSString *component in components){
if (!isInFrenchStopWords(component)){
NSMutableArray *orSubPredicates =
[NSMutableArray new];
[orSubPredicates addObject:[NSPredicate
predicateWithFormat:@%@ IN[cd] self.name,component]];
[orSubPredicates addObject:[NSPredicate
predicateWithFormat:@%@ IN[cd] self.description,component]];
[orSubPredicates addObject:[NSPredicate
predicateWithFormat:@%@ IN[cd] self.addInfo,component]];
// build a OR Predicate for this particular
keyword.
[keywordsSubPredicates
addObject:[NSCompoundPredicate orPredicateWithSubpredicates:orSubPredicates]];
[orSubPredicates release];
}
}
// keywords are combined in a AND predicate, all keywords must
have a hit.
[finalSubPredicates addObject:[NSCompoundPredicate
andPredicateWithSubpredicates:keywordsSubPredicates]];
}
Then if there are selected categories these are also predicated as so.
the selected categories ManagedObject are stored in an NSDictionary
A predicate is built for every selected category, because it is a many to many
relationship.
i've tried using category.name but that did not work.
if ([self.categoryPredicateDict count]){
NSArray * components = [self.categoryPredicateDict allValues];
for (ModelCategory *component in components){
[categoriesSubPredicates addObject:[NSPredicate
predicateWithFormat:@%@ IN[cd] categories,component]];
}
// or any selected Category
[finalSubPredicates addObject:[NSCompoundPredicate
orPredicateWithSubpredicates:categoriesSubPredicates]];
}
A predicate is built for every selected element, because it is a many to many
relationship.
if ([self.elementPredicateDict count]){
NSArray * components = [self.elementPredicateDict allValues];
for (ModelElement *component in components){
[elementSubPredicates addObject:[NSPredicate
predicateWithFormat:@%@ IN[cd] elements,component]];
}
// or any selected elements
[finalSubPredicates addObject:[NSCompoundPredicate
orPredicateWithSubpredicates:elementsSubPredicates]];
}
and then to finalize everything and put it all together.
return [NSCompoundPredicate andPredicateWithSubpredicates:finalSubPredicates];
then this predicate is fed to a fetch Request which in turn is fed to a fetched
Result Controller.
the fetch is configured to [fetchRequest setReturnsDistinctResults:YES];
The problem as stated in the introduction this complete predicate returns
multiple instances of the same record and it should not.
if any of you see a flaw in the logic or anything, please comment, I'm
currently so deep into it, I cant see it anymore. :)
I hope I have not missed nay
[iPhone] HTTPS / client Certificate / configuration profile
Greetings. Scenario: Our application accesses the content of a secure web server, the server is configured to ask the client for a certificate. and other security features. HTTPS 1: SSL connection to server with server certificate 2: SSL Client certificate (different cert issued for every user) 3: Basic Auth authentication over SSL. I've looked at the docs and took some code from Apple's advance NSURLConnection ...the server certificate challenge works fine. When I get to the client certificate challenge the code does not seem to be able to find the client certificate. I've tried installing the certificate 1: as part of a configuration profile...(iPhone config utility) 2: certificate sent in an email to the phone and installed directly on the phone The code from the advance NSURLConnection looks for certificates in the keychain, but does not seem to find anything to process and send back to the server. So my question is, how do I access a certificate that has been installed on the phone that does not seem to be in the keychain? Thank you for any pointers. best regards.

Re: [iPhone] HTTPS / client Certificate / configuration profile
When you tell Install certificate, I guess you mean Certificate and private key isn't it ? Yes the p12. Does it works if you try to log using Safari ? I'm using it to access https with cert based auth, and don't get any problem. Will try that and get back with the report.

Re: [iPhone] HTTPS / client Certificate / configuration profile
Yes it works. Thanks for the hint. Safari first asks me to accept the server certificate. second step it warns me that the web site demands a client certificate and asks me to choose one from a list. once selected i am prompted for user name and password from the server. Which is the intended process. I get the proper challenge from NSURLConnection delegate selectors. somehow my application does not find the certificates when it is being challenged for the client certificate. I must be doing something wrong in the lookup. to be honest all this authentication is still a little blurry for me at this point. I understand the concept...where should i look up for the certificates/credentials... it is somewhere else than the keychain ? to query the keychain I currently use... [NSDictionary dictionaryWithObjectsAndKeys: (id) kSecClassIdentity, kSecClass, kSecMatchLimitAll, kSecMatchLimit, kCFBooleanTrue, kSecReturnRef, nil], [NSDictionary dictionaryWithObjectsAndKeys: (id) kSecClassCertificate, kSecClass, kSecMatchLimitAll, kSecMatchLimit, kCFBooleanTrue, kSecReturnRef, nil], both query come back empty. Added info: The Configuration profile's Identity is the same as the Bundle identifier and the Entitlements application-identifier and the keychain-access-groups as i read, the applications only access keychains for their access groups. if that makes a difference...

Re: [iPhone] HTTPS / client Certificate / configuration profile
As i replied earlier, it works just fin in Safari for the iphone . as i mentioned, the problem lies in getting the certificate out of the configuration profile, from the within application. Historically, client certificates haven't really worked properly in Secure Transport, and therefore also not from Safari or from NSURLConnection. I don't know if this has been fixed or not; it's been a while since I tried using client certificates for authentication with OS X.

[iPhone] UIButton and Device Orientation problem in MainWindow.
Greetings. I am trying to draw a UIButton in the application's main window so the button remains visible no matter what the user does in the sub view's. (TabBar based with a bunch of NavBars.)... This works great in the default device orientation. But left, right and upside down, the orientation of the button remains as if it was upright. I've tried adjusting the coordinates but the image drawn inside the button does not change orientation. when the phone is upside down, the image is upside down but the rest of the interface is well positioned. I'm sure the trick is simple but I can't seem to find it in google, or i'm not using the right therms. can someone point me in the right direction ? please :) Thank you all!!

You simply mustn't put the button in the window; it must go into the root view, the sole subview of the window, which is placed there and managed by a UIViewController. Start your app with the UIView-based App template and work from there, building your interface in the secondary nib. Read up on view controllers in the docs, which are excellent on this point. You may have to unwind the whole way your interface is constructed in order to do this, so start with just the button and add stuff back after you get that working. m. -- matt neuburg, phd = m...@tidbits.com, http://www.apeth.net/matt/ A fool + a tool + an autorelease pool = cool!

my model is as so.
member is part of a category
the category has a name.
while in a member resultset i want to filter the content on category names.
[NSPredicate predicateWithFormat:@(caregory.name IN %@),[selections
objectForKey:kPredicateFieldNamesArray]];
I crash with:
'unimplemented SQL generation for predicate : (caregory.name IN {Boutiques})'
I've otherwise tried:
[NSPredicate predicateWithFormat:@(carego...@name IN %@),[selections
objectForKey:kPredicateFieldNamesArray]];
'Unsupported KVC aggregate in keypath: carego...@name'
Am I missing something?
I thought KVC was part of the Predicates.

Not to state the obvious, but you did notice that your code has misspelled
category, right? Is the property name correct?

NSKeyedArchiver on OSX to NSKeyedUnarchiver iOS
Greetings
I'm having problems unarchiving my data in the iphone.
here is the workout.
1: I archive a AttributedString to my CoreData NSData property using
NSKeyedarchiver
2: Transfer the database to the iphone.
3: load the data using NSKeyedUnarchiver on the iphone.
NSAttributedString *as = (NSAttributedString*)[NSKeyedUnarchiver
unarchiveObjectWithData:attributedStringData];
that crashes saying:
-[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (NSFont)
I understand that the NSFont is UIFont on the iphone, or has similarities.
so i implemented a Delegate method to replace the class.
//--
- (Class)unarchiver:(NSKeyedUnarchiver *)unarchiver
cannotDecodeObjectOfClassName:(NSString *)name originalClasses:(NSArray
*)classNames{
if ([name isEqualToString:@NSFont])
return [UIFont class];
return nil;
}
but that never gets called because the class method does not allow for a
delegate and instantiating the unarchiver class confuses me in how I should
trigger the decoding once it is instantiated.
Any pointers ?
Sandro Noel.

That's a good idea, i did not think of that, i could store the basic properties and rebuild it on the other side... a little more work but independent. thank you! Sandro.

[iPhone] UITableViewCell Height with UIWebView content
Greetings.
I've been trying to set the table view cell's height for a custom tableviewCell
containing a UIWebView
to display attributed content but i cant's get the height properly.
I am using a UITable View with sections, the first section shows a list of
child objects
and the second section displays the current node's text.
Here is the explanation of my workout. yes it's a workout.
1: define a custom TableCellViewCell in interface builder, containing a
UIWebView.
2: the UITableView is given a HTML String before being pushed on the Navigation
view.
3: in the cellForRowAtIndexPath the cell is given the HTML String
4: i've also implemented the heightForRowAtIndexPath method. which calls a
function that calculated the height of the cell using the text as source.
- (CGFloat) heightOfCellForString:(NSString *)string
inTableView:(UITableView*)tblView andFont:(UIFont *)font{
CGFloat minimumCellHeight = 44.0f;
CGRect tableViewFrame = [tblView frame];
CGSize textSize = { tableViewFrame.size.width, 20.00f };
CGSize size = [string sizeWithFont:font constrainedToSize:textSize
lineBreakMode:UILineBreakModeWordWrap];
// if there is more than one line add a little padding..
if (size.height 21)
size.height += 25;
CGFloat result = MAX(size.height, minimumCellHeight);
return result;
}
This function works great for ordinary cells, but falls verry verry short when
it comes
to resizing the cell containing the UIWebView,
is there a effective way to tell how high the tableviewCell should be to
accommodate the UITableCellView
at the heightForRowAtIndexPath stage?
since it is so tedious, Now i'm thinking this is a design flaw on my part,

Re: [iPhone] UITableViewCell Height with UIWebView content
Glenn thank you, I will revisit the design. as for using Core Text, I read the doc, but unfortunately for me I'm still novice at drawing stuff. I need to read more about it as it is the only way to get exactly what I want from the platform. so it is in the top of the todo list. best regards. Sandro. Rethink your design - putting a UIWebView inside a UITableView is usually a bad idea for a number of reasons, including: - not being able to tell the height of the view until far too late to be any good (UITableView needs to know before it is displayed, UIWebView can't know until after everything has been loaded) - views which scroll vertically inside other views which scroll vertically can cause a bad user experience (though at least as of 3.x they work - in previous OSes the results were far less useful), - UIWebView is a very heavy weight view, and UITableViewCells are designed to be light weight You should probably put the resulting UIWebView in its own view controller, and push that as a disclosure of the table cell (or detail disclosure). If your goal is just to display styled text inside a table row, you can use things like NSAttributedString/CoreText (or for pre 3.2 support, CFAttributedString custom drawing routines).

AttributedString from NSData on iPhone.
Hello. I'm trying to take an attributed string from a PDF document and reproduce it on the phone. passing thru a SQLite Database. basically, i write to the database using NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObject:NSRTFDTextDocumentType forKey:NSDocumentTypeDocumentAttribute]; [dict setValue:[NSNumber numberWithInt: NSUTF8StringEncoding] forKey:NSCharacterEncodingDocumentAttribute]; NSData *stringData = [[tempString dataFromRange:range documentAttributes:dict error:error] copy]; node.attributedStringData = stringData; *Node is my Managed Object Model entity, tempString is the attributed string from the PDF. So all the attributed strings get inserted into the database, and that database is sent to the iPhone Back on the iphone, I'd like to restore that attributed string from core data to an NSAttributedString object. and write that attributed string into a custom UITableViewCell, presumably using CoreText. any pointers on how that could be done? or am I over doing it and missed out on a cool class that does it all for me... as usual... best regards Sandro Noel.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[iPhone] Data protection clarification needed.
Greetings. I've been looking for information on how the data protection works on the iPhone and I've watched the WWDC video session 209. but I might have misunderstood. what I understand is that the data is protected as long as the phone is locked. otherwise, it is accessible. with options of syncing that protected data to other devices. What we want is for out application Data to still be locked when the phone is unlocked and only unlocked by the user when the user logs locally in to the application. the data should not sync or be backed up onto any other device. it is after all strategic data, so we need to be really careful about it. is it at all possible to enable data encryption of our Core Data store independently of the user's unlock of the device and only make the data accessible when the application has authenticated the user, while still benefiting from the current (do not sync data) features of the current API implementation? I hope I'm being clear enough, my understanding is still a little blurry. Best regards.

There is no need for that data to be backed up anywhere, as it is retrievable from the web service. the cached data is used for offline operations and later synced back to the web service. We want to control when the data becomes available in an unencrypted format. and that would be when our application is the active application, otherwise in the background or terminated, the data is encrypted and inaccessible.

iPhone TabBarController and NavigationController with Core Data
Greetings. I've been at this for a week trying to figure things out and I'm getting nowhere. This is my first iPhone application so please be gentle. ok, I created the application from the tab bar application template, and checked core data stack support. created the model and imported startup data. Second I added navigation controllers to the Tab bar as seen in an example I've found on the internet or the apple documentation. I've connected all the nib files and the application works nicely when built and run in the simulator. The time has come to populate the table views and i'm completely confused on how to go about it. the layout, MainWindow.xib: Tab bar contorller Navigation controller View controller (loads SearchView) (other navigation controllers)... SearchView.xib: TableViewController (custom controller defined) TableView SearchBar now, inside the tableViewController i have a fetchResultController configured, but this guy needs a managedObjectContext which is in my Application delegate I've seen examples where the tableview exposes a property to set the local managedObjectContext but all the way back to the applicationDelegate is a place where no events happen where i can set the property on that specific TableViewcontroller. I'm sorry if i don't explain this correctly, i'm so lost i don't even know where to look now. looking at the examples (unless i've missed it) it seems i'm trying to so something extraordinary. or so easy there is no need for an example ( then i'm really off track ). Can someone please give me a pointer on how to get my managedObjectCOntect to my tableViewControllers? best regards.

I have a very similar application requirement. In my case, I am using 2 separate persistent stores. One is the user store located in their documents directory to maintain their unique copy of the database and edits to the provided data. The second is part of the application bundle. In this case, I use 2 separate MOC's and migrate data from the app persistent store to the user persistent store. Using the metadata that can be stored with the persistent stores, I check a version key I create and then if it is different, do a merge of the 2 stores. See the core data docs for a method for efficiently doing a large comparison and merge. This has worked quite well and allows for application database updates without messing up any unique changes the user has made to their own earlier copy. Doing it this way also protects the user if the application is reloaded. The user data in the documents directory is backed up and can easily be restored. As for model changes, if they are simple changes to the model between versions, you may be able to get away with lightweight migration. It is a simple option to add when loading the persistent store. There very well may be a better approach but this has successfully worked for me.

Re: Monitoring other application preferences changes
If I remember correctly, the Apple application you're interested in is the Dock. As I mentioned previously, you'll receive NSApplicationDidChangeScreenParametersNotification notifications (and -applicationDidChangeScreenParameters: delegate method invocations) when the Dock's position or size changes in such a way that the visible frame of one of the screens changes. Otherwise, what you're trying to do is unsupported. However, you can still use NSDistributedNotificationCenter to learn the undocumented, unsupported, unreliable distributed notifications that Apple is using to broadcast the changes in its preferences. Just register yourself as an observer of all distributed notifications and log them. Then, poke at the Dock's preferences in System Preferences and/or the Dock's contextual menu. You'll see the distributed notifications go by. Whether you want to base a commercial product on such unreliable Apple-private mechanisms is a judgment call. Regards, Ken Ken the Dock is one of the applications I wanted to monitor, thank you for the valuable pointers, Most appreciated! cheers!

Drop destination works like a charm for me, just by implementing the
NSCollectionViewDelegate protocol as part of my window controller
the delegate being set for the Collection view in interface builder as the
window controller.
There are also methods for the drag Source but i can't seem to get them working
properly.
I can drag my item from the CollectionView to another CollectionView, the drop
get's accepted
but then, i get an error about URL's, i've never asked for URL's as a mater of
fact my destination accepts only one type.
NSFilenamesPboardType
which is an array of strings containing file path.
that is exactly what i construct to past to the pasteboard as so.
- (BOOL)collectionView:(NSCollectionView *)collectionView
writeItemsAtIndexes:(NSIndexSet *)indexes toPasteboard:(NSPasteboard
*)pasteboard{
ENTERING();
[pasteboard clearContents];
[pasteboard declareTypes:[NSArray
arrayWithObject:NSFilenamesPboardType] owner:nil];
// we only allow one object to be selected.
DItem *object = [[itemsArrayController selectedObjects]
objectAtIndex:0];
[pasteboard writeObjects:[NSArray arrayWithObject:object.path]];
return YES;
}
[30040:a0f] Looked for URLs on the pasteboard, but found none.
any clue is welcome.

How would i go about it ? 1: when the item is dragged out of the frame, I want to remove it from the collection view as to show that I am holding the item out of the collection ( i got it in my hands and it's in limbo ) 2: I could at any point drop the item back on the collection view as to cancel the deleting of the item 3: I could drag the item to another collection view in the same application as to move the item around. 3: if the item is released outside of any collection view it is lost (deleted). if anyone can point me to a good example, that would be great.

Re: Dock position and size
the reason why i want to know the position of the dock is because i want to latch on to it, over it. and i would like to be of the same width and same proportions.

Re: Dock position and size
Well the application I'm trying to do is a something I like to call a Dock-Stack. No it's not like those folders stacks. It's docks that would autohide and appear right under the dock window, but pop up just above the current dock. kind of an extension to the dock. (in the case my application is configured to be on the same screen edge as the OS Dock) I love the Dock but I find it limited. I've always wanted to have the option to have multiple docks live. without having to change the configuration like other applications offer, I want to have another dock either as a stack or as an independent one on other screen edges. and i have not found an application that does it like i want it to be. So i'll do it :) Voila. the secret is out.

I might be wrong and you may have a great reason for wanting to do this but it doesn't seem very Mac-like... There's possibly (probably?) a better way to design your interface that doesn't require latching on to the Dock. Remember: - the dock may be on the left, right or bottom of screen (or even the top of screen for those who like messing about with unsupported preference settings) - the dock may be set to auto-hide - the dock may be set to grow when the mouse moves over it (will your window resize every time these users mouse over the dock)? - the dock will grow and shrink as apps are added/removed/launched/quit - the dock will grow and shrink as windows are minimised and restored - users can (and will) resize the dock on a whim - users can (and will) change their dock hiding settings regularly (particularly those on lower res screens such as laptops or older machines) Of course if you're just trying to do this for an app for yourself go nuts!

Re: Dock position and size
This sounds like a pretty challenging task, especially given the fact that the Dock itself is so tightly coupled with many other OS X technologies (Spaces, Exposé, etc). Probably the closest utility to achieving this goal and still maintaining compatibility with these OS X niceties is Docks, formerly distributed by Thoughtful Tree Software and soon by Big Nerd Ranch. (There are other similar utilities, but I recommend Docks, on the basis that I wrote it and am thus biased.) But by all means if you want to try and write a new solution, go for it. Just remember how tightly integrated into OS X the Dock is, because a lot of people count on that fact. -Steven The approach of your project is very original, switching docks while switching spaces is a great feature. unfortunately not what I am trying to achieve, I'm extremely lazy clicker, I do not want to have to remember in what configuration of the dock I placed this and that application. I want them in my face all the time. I understand that not all user have a need for such a thing or screen real-estate, but I do. I think I found my solution, there is a way to guess the dock width it heroic but :) width = tilesize * (items in he dock) + (width of separator [scaled proportional to height of separator] ) + (tile separation pixels)) height = screen frame - visibleFrame if i recalculate it every time the window is shown i should be close to the spot most of the time. the zoom of the dock is irrelevant as it does not change the visible frame. any comments are welcome.

NSDrawNinePartImage not working ?
Ok I know I must be missing something dumb.
i'm trying to draw borders for the window,
- (void) awakeFromNib{
[window setStyleMask:NSBorderlessWindowMask];
[window setOpaque:YES];
NSDrawNinePartImage([[window contentView]frame],
nil,
nil,
nil,
[NSImage imageNamed:@right3.png],
nil,
[NSImage imageNamed:@left3.png],
[NSImage imageNamed:@right4.png],
[NSImage imageNamed:@left5.png],
[NSImage imageNamed:@left4.png],
NSCompositeClear,
1.0,
NO);
but i get an error on runtime.
Error: CGContextGetStyle: invalid context 0x0
It does not make sense to draw an image when [NSGraphicsContext currentContext]
is nil. This is a programming error.
Break on _NSWarnForDrawingImageWithNoCurrentContext to debug. This will be
logged only once. This may break in the future.
CGContextClipToRect: invalid context 0x0
Error: CGContextSetAlpha: invalid context 0x0
Error: CGContextGetUserSpaceToDeviceSpaceTransform: invalid context 0x0
Error: CGContextDrawTiledImage: invalid context 0x0

Error: CGContextSetAlpha: invalid context 0x0
Error: CGContextGetUserSpaceToDeviceSpaceTransform: invalid context 0x0
Error: CGContextDrawTiledImage: invalid context 0x0
I looked in the docsa little but did not find any indication that i had to
provide a Graphics context.
any pointers ?
Sandro.

You should be drawing from drawRect:, not awakeFromNib. http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/ CocoaDrawingGuide/Introduction/Introduction.html Also, IIRC, you can only make a window borderless at init time.

The esc Key is trapped like this inside the View controller that is loaded
inside the window.
-(BOOL)control:(NSControl *)control textView:(NSTextView *)textView
doCommandBySelector:(SEL)command
{
if (command == @selector(cancelOperation:)) {
NSLog(@escape key has been pressed);
}
return NO;
}
I do not have access to the window instance.
How do i get to the window?

Just make the outline view itself first responder. This will validate and
resign the text field if it's OK.

Apple MVC and Document Based application confusion.
Hello. I'm reading COCOA Design Patterns from Eric M. Buck Donald A. Yacktman. and i'm having a hard time applying the principle in my architecture. for example, if i create a new document based application in XCode, the MyDocument xib file binds the window outlet to the MyDocument Class. From what I read the MyDocument Class is supposed to be a model controller, not the window controller. The MyDocument Class is supposed to be able to host an array of window controllers. I see that makes sense if I have a main data view window and I would want to associate an inspector to that window and share the same data source with both windows. and I like that idea. what i am unsure of is how to go about with interface builder, and where should i associate the view with it's controller inside the MyDocument Class? ( but i read that model should have no knowledge of the view) is it the same for the Model Controller? if it's not then MyDocument Class becomes more than a Model Controller it is also a Window controller. in witch case why bother creating separate View/Window controllers? and why host an array of window controllers? Do i create the Window controllers in IB or do i do it in code, and how would i go about doing that the right way? I'm kind of confused and I'd really love some clearing up. thanks for any pointers.

I would use a different image for every state.

Re: Custom Controls Where to start
Thank you Alastair. Well it's pretty complicated, This is my third application, the first being Bonjour Mounter, the Second RDP Launcher. Others were created but never released. I've always used the OS's controls but now I find myself frustrated with the limits of these controls in terms of looks. I see other application makers producing great looking applications with custom looking views and controls. So I want to be able to know where to start and what to think about when I create a control, a view. I did venture to read the Doc documentation, there is much there but so much it becomes confusing. for example, the look of the segment control does not fit the look that i'd like it to have, i find it's a good enough starting point to create a tab bar, a little like Safari, and add the close tab button and some status information on the right end of the tab. along with a scrolling title like on the Apple TV. From what I understand, all I would have to do is create my own cell. Also, the controls for the HUD panels are missing, there is BWHUDAppKit.framework that does partial of the work witch is amazing. but it is not complete, i like to use the CollectionView control, and it hans not been implemented, so i'm off to do it myself. there are also table cels missing, i would like to create those too. I think that once I've done these I would pretty much be able to create my own out of this world looking controls while preserving HIG intact. and it will also give me a better understanding of the underpinnings of cocoa. I also want to write a control/view that incorporates some of the features of most code editors, code folding, code colouring and such out of the box. but that is not for now. Sandro.

Some start from NSControl with a combination of NSCell and NSActionCell Yep. Others Start from NSView, and some start from Apple's controls and override the drawing. Yep. What i am trying to achieve is 1: to be able to change the look of the controls that already exist if i need to. In which case you'll have to look how the control in question is implemented. If it's an NSControl subclass, you probably need to subclass the corresponding NSCell subclass in order to customise it. 2: if I have the need for a control that does not exist, i want to be able to create it myself. including having to respond to user input and mouse clicks and send those back to the caller ( thru delegates or actions ) If it smells like an NSControl (e.g. a button or something), then using a custom cell is probably the best way to go. Especially if there's already a matching subclass of NSControl (e.g. NSButton), in which case you can subclass NSButton and NSButtonCell and get most of the existing button functionality for free. If it doesn't look like that, for instance it's some new control that the system doesn't have, or it's the main document view of your app or something, then NSView is probably a better bet. NSControl and NSCell have the advantage that they do various things for you, *and* you can create an NSMatrix of your new cell class, or stick it into an NSTableView. If you're using a custom NSView, it's harder to put it into a table view, and you have to handle everything directly yourself, but, on the other hand, you only have to write one class and it's perhaps slightly more apparent how to handle e.g. mouse events than it is with NSCell (I know that's something I struggled with at first). I'll also add a warning. While you can create custom controls, it's important to consider carefully whether they're necessary. Making controls that look or work in a manner that doesn't match those in the HIG is probably a mistake, unless you have a good justification for it (and looks/works like Windows, although a common justification, is wrong). If you want more specific advice, you'll have to be more specific about what you want to achieve.

Re: Where are the interface builder components?
OK, so you want one of these controls yourself? Well, let's imagine you're going to sit down and write one for your app. Are you honestly telling me that you expect to end up with highly reusable code that could be placed in a framework like Cocoa, and you'd be happy to ship to a large number of other developers? Or (and far more likely) that you'll have implemented only the bits of functionality your own app needs and left plenty of holes to fill? Please i'm not trying to offend anyone here, i was just questioning... but since you ask. I try my best to design my classes with the re-usability in mind, also to the best of my knowledge of the language at the time of design, mostly because I do not like to have to rewrite things, it's a waste of time, efforts and money... occasionally I will rewrite a class to improve it with new acquired knowledge and techniques yes, for instance when i learned that i could iterate thru a collection using a for loop instead of while loop coupled with an iterator, i did change most of my classes to reflect that ease of use. same thing for when I learned of properties and KVM coding. Additionally I always write my code with someone might need to use this kind of approach, it takes me a little more time but it's worth it in the end. If I was to provide quality development tools to my users, I would make sure my employees have that mindset when hacking together a class, yes, because the time spent un-mixing the mess afterwards to release proper components is just to costly. 1: it takes them away from the creative bench to think of new features 2: it doubles the initial effort therefor doubling the cost, in human hours. Unfortunately for me right now i do not believe I have proper and all the handles on cocoa to create my own controls, but i'm getting there My first controls will probably have holes and missing features, and might respond to specific needs, but then again i'm one guy with less than a year of experience with cocoa. Tho I try my best to measure up, I'm not Apple. This thread of emails want not intended to bash Apple for not doing their work, I just needed to understand why the components are not already available in the toolbox when it seemed logical to me that they should of been there with the release of the operating system along with all the new features so application developers could take full advantage of it.

Re: Where are the interface builder components?
This is what i think from observing the applications apple released witch have controls that are not in the tools palette. * Must work with localized content That's already implemented in the controls used by apple in their application. * Must work with accessibility also already implemented in the controls used by apple in their application (for the most part). * For particular controls, probably need to have multiple sizes (large, small, mini) already implemented visibly in the controls used by apple in their application. * Probably will need to expose custom bindings Apparently iLife and most of the released applications with snow leopard are coded in cocoa, the finer for example is now a cocoa application, * Should work in resolution independence. That i'm not sure of, but considering that Binary God ( BGHUDAppKit) was able to do it properly i imagine the brains at apple can do as much, * Probably some other things I'm missing. Maybe i'm just talking out of my hat here, because i'm not in the secrets of the gods, but looking at what is in the applications already... I'll file a request. thank you for the advice! Sandro.

True, but keep in mind the amount of effort that Apple would need to do if they provided the custom control, etc: * Must work with localized content * Must work with accessibility * For particular controls, probably need to have multiple sizes (large, small, mini) * Probably will need to expose custom bindings * Should work in resolution independence. * Probably some other things I'm missing. Definitely file an enhancement request though. I'm sure Apple will strongly look into providing something if several developers end up asking for the same type of controls. ___ Ricky A.

Re: Where are the interface builder components?
Thank you all for your feedback! I guess i'll have to make my own. I just find it sad to have to duplicate work, it's unproductive. cheers! Sandro Noel.

I'm confused as why apple is not including it in it's development tools. it makes no sense to me... Because it takes longer to release new UI widgets as general-purpose tools than it does to create them in isolation in a single app? Because it takes more work to create a widget + an IB plug-in that it does to code up the widget in an app? New plug-ins *have* been added to IB some time after widgets show up in Apple apps (toolbars come to mind), but Apple can't do everything at once and they're certainly not going to hold up shipping new features in iWhatever just because you'll want the IB plug-in at the same time. Any particular widget you have a need for, file an enhancement request... -- Scott Ribe scott_r...@killerbytes.com http://www.killerbytes.com/ (303) 722-0567 voice ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Where are the interface builder components?
Greetings. I'm kind of annoyed with the 1867 A.D. controls that are in interface builder. Every time i want to do something visually cool, I can see the lines of code piling up I'm wondering where all the good stuff is, (interface builder components) Evidently Apple has some cool components in their library, for example the Hud controls. The safari tabs, toolbar controls with multiple view's Where can I get my hands on that? Is it part of the ADC Membership? Do I have to learn to code these wonders by hand? Am I missing something fundamental? Something I should read up to get satisfaction in my creative adventures? Thank you for any pointers.

Dave Wow, cool Link, thank you! very appreciated! But where are the ones from apple... that's what i'm wondering, Why do we have to duplicate work that evidently has already been done.
