Re: [IB] - how to delete action or outlet?

Are you actually saving changes to the AppController source files after you edit them? As I wrote, when I opened IB for the first time, Actions panel already had AppController.h title and contained my previously declared action. Therefore I thought IB was synchronized with the source file. Am I incorrect? On a second note, the - button is gray because you can only remove actions in IB that you've added in IB. Nice! And how to remove that action or at least how to rename it? For example I've done it by mistake, for testing or similar purposes. Now I can't remove such action or outlet, though I've closed IB, removed the action from the source file, then opened IB again. The action (or outlet) still exists in the object properties list. I think the only way to remove it is to edit XIB file manually - not a simple way, isn't it?

Core Data design patterns
Let's say I have the usual Employee and Department entities. Throughout my application I have to do fetching. I have simplified my code by making a helper class called CoreDataHelper, which has all kinds different helper methods, such as +(NSArray *)employeesInDepartment:(NSManagedObject*)department inManagedObjectContext:(NSManagedObjectContext *)moc; And lots of others like it, as per my needs. As you can imagine, the list will grow with time as I need to do different types of fetching around my app, and as I add more entities. The advantage of using this method is that I save myself a lot of NSFetchRequest *fetchRequest = ... type of code lines throughout my app. On the other hand, a possible drawback is that I might be breaking some design principles. If this is the case, can you tell me why this is bad? In fact, I can think of another variation of my method. Namely, to not have class methods in CoreDataHelper, but rather instance methods and initialize the CoreDataHelper with the MOC. The advantage of this would be that I would not have to pass the MOC into each method call. The drawback is that I have to create a CoreDataHelper instance each time I want to use its methods. A third variation would be to simply do either of the two variations above, but not pass in MOC anywhere and instead just use [[NSApp delegate] managedObjectContext] whenever I need it within CoreDataHelper. But I believe this third variation is plain bad as it relies on some special app delegate to be present, making a model object be depended on a controller object, breaking the MVC guidelines. What do you guys think? How would you do this stuff? A more general closing question: How do you make your code more organized? It's just that I've been typing these thousands of lines of code and all this time I've had this strange feeling that there is just something awful about my code, but without knowing what exactly is wrong. For instance, I've gotten to the point where lots of model/controller/view code, which should be separated somehow by MVC, are mixed together. Not completely mixed of course, I try to think of MVC and have some separation with respect to that, but there is still some mixup here and there. At least that's what I feel. The thing is just, I can't always see clearly how I would make the separation. Making me feel a bit bad. Any antidotes? Maybe reading some good design principles book will help? Or getting a degree in CS? How did you guys learn this stuff? -. _ Invite your mail contacts to join your friends list with Windows Live Spaces.

Re: missing vertical scroll bar
The topic of creating a Cocoa app without using IB has come up many times since I've been on this list, and the general opinion is you should always use IB unless you've got a really good reason not to. IB's not a toy, it doesn't make you any less of a programmer, it's not going anywhere, and it's just how we do things. :) You may struggle with IB in the beginning, but give it an honest effort and you'll find yourself writing less code and better software. Perhaps you could give a detailed description of what your UI should look like, and we can tell you the IB way to do it? Nothing of what you've mentioned so far is beyond the abilities of IB. Some notes: o execution-time-specified number of windows: This makes me think you need a document-based app. Also check out NSWindowController. o text view imbedded in a scroll view: In IB, any text view is by default embedded in a scroll view, no code necessary.

In any case, something needs to be fixed, or I need to be shown what I'm doing wrong. a. It's #4. Possibly with a tiny bit of #1. It really is possible to create windows and views programmatically. There is no bug in the framework. (At least, you'd have to *prove* that there is. These NSView APIs have been tried and tested countless times.) b. You'll likely have trouble getting expert help on this, because the expert help on this list will likely think it's waste of time to do it programmatically. c. A far better approach is to use IB to create the pieces you want to assemble at run time, each as a separate view subtree, probably but not necessarily in a separate NIB file. Then you have only two things to do at run time: add the subtrees to your window's view hierarchy (which is very easy), and resize the subtrees you add to your window's view hierarchy (sometimes fiddly, but writing code to resize views is much easier than constructing the views). If you've set the autoresizing up right in your NIBs, then often all that's necessary is to resize the subtree root view to fit view it's becoming part of, and everything else just happens automatically. d. Debugging hand-constructed views is a much bigger PITA than pretty much any way of doing it that involves IB. e. Notwithstanding a-d, your app *may* have a valid reason for doing this the hardest way, but if so we haven't heard it yet.

Loading GC test bundles
Hi, I'm the developer of a GUI for OCUnit called OCRunner. I'm having an issue with loading test bundles that use GC into the app. It brings up the following error: 18/07/2009 2:37:05 pm OCRunnerTool[9566] Error loading /Test/Binary/ Path: dlopen(/Test/Binary/Path, 265): no suitable image found. Did find: /Test/Binary/Path: GC capability mismatch This appears for both my foundation tool which runs the test (OCRunnerTool) and the GUI app that displays the results (OCRunner). Both these run fine except they show no tests run, probably due to the bundle simply not being loaded. At first I thought the problem was that GC was set as unsupported on both of these targets but setting it to either supported or required brings up the same issue. I've looked around but the only thing I've found relating to OCUnit and GC is something about framework tests running with GC required not being supported in Xcode 3.0. The tests run fine using the default run tool included with the dev tools. The project is open source and the source can be found at: http://bazaar.launchpad.net/~pilky/ocrunner/dev/files . Hopefully a different pair of eyes (possibly one with more experience with unit testing with GC) might be able to see something I'm missing. The code that deals with running tests is /OCRunnerTool and AppDelegate.m:102-166.

It would be for displaying static rich text (certain things are harder, or maybe even impossible, to do with NSTextField).

I do *not* create the NSTextView in IB, but rather do so programmatically. You'll need to call its - initWithFrame method to initialize, and then add as a subview to its containing view. I also interact directly with the underlying text system (Text Container, Layout Manager, and Text Storage) in order to set the text, determine the size of the laid out text, and position for presentation and interaction.

Custom NSArrayController - Dynamic Class?
I have a Core Data app and several tables for adding various
entities. I want to add an index to each new object so I can sort
them after fetching. I've been using a custom NSArrayController and
overriding the addObject:, insertObject: atArrangedObjectIndex:, and
removeObject: methods to add or update the indices as I go, using, for
example:
- (void)addObject:(Floor *)object {
[super addObject:object];
object.index = [NSNumber numberWithInt:[[self arrangedObjects]
indexOfObject:object]];
NSLog(@Added %@, [object description]);
}
This means that I need a custom NSArrayController for each entity. Is
there a way to make the entity name dynamic? In other words, can I
ask the array controller for the name of the entity it's managing, so
I only need one custom NSArrayController subclass to manage this for
several different entity types? I guess I'm looking for a way to
replace the argument (Floor *) from the example above with something
like:
[[[self arrangedObjects] objectAtIndex:0] class]
If I use id, the code doesn't know that the object being added should
have an index.
Thanks.

DKJ wrote: Yes, I realise that. What I'm wondering is where to do it, since it's initialised in the awakeFromNib method, rather than in initWithFrame:. It doesn't matter where it's initialized. The only thing that matters is who owns it. It is not only possible, but fairly common, for an instance of some class to acquire ownership of additional objects over time. As a simple example, consider an instance of NSMutableArray. In order for it to work properly, it acquires ownership of every object added or inserted. So ask yourself what should the dealloc method of NSMutableArray do? The answer should be obvious: it should release every object it still owns, regardless of when the object was acquired. You should probably reread the Memory Management section if this isn't crystal-clear. I'm not just being pedantic about this, either. Ownership is *the* fundamental principle behind all questions of memory management, and if there is any question in your mind about what ownership means or what its responsibilities are, then rereading the memory management docs is the best thing to do.

NSDateFormatter issue (bug maybe)?
Hi All, Thanks in advance for any help on this issue. I have a file that uses the following format for date and times: (4 digit year)-(2 digit month)-(2 digit day)T(2 digit hour, 0-23):(2 digit minute):(2 digit seconds)-(4 digit offset from GMT) Example: 2009-07-17T17:12:20-0700 I am using an NSDateFormatter with a custom date format to read these dates. formatter = [[NSDateFormatter alloc] init]; [formatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [formatter setDateFormat:@-MM-dd'T'HH:mm:ssZZZ]; On the Mac this works great for any combination of Region setting and 24hr/AM,PM settings. On the iPhone (both iPhone OS 2.2.1 and 3.0) this does not work if the Region setting is set to something that defaults to 24hr time (like UK, France, and Thai) but the time display setting is set by the user to AM/PM. For example: on the iPhone if in Settings you set the region to UK and turn 24-Hour Time off. When the phone is configured like this the above code wants to read and write dates with the following format. (4 digit year)-(2 digit month)-(2 digit day)T(2 digit hour, 0-23):(2 digit minute):(2 digit seconds) (AM/PM)-(4 digit offset from GMT) Example: 2009-07-17T17:12:20 PM-0700 This is not the behavior I would have expected. Am I configuring NSDateFormatter correctly? Is this a bug I should file in Radar? Again any help is greatly appreciated. We have an app in the App Store with this issue and it is causing some customers issues.

But I'd sleep better having an expert opinion. Work it through. If you understand ownership, you already have all the expertise needed. Can awakeFromNib be called more than once on the same instance? If so, then in awakeFromNib you need to account for the possibility of shadingAreas already holding a non-nil (hence, an owned) NSDictionary instance. The reason is simple: you own that non-nil instance. What should you do if you discover a non-nil shadingAreas in awakeFromNib? It depends on you and your design. You could use the existing instance, if that makes sense. You could release the existing instance and alloc/init a new one, if that makes sense. You could trigger an assertion that fails if this happens, it that makes sense. None of this has any bearing on what you'd do with shadingAreas in dealloc. You have to consider ownership in each method separately. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Custom NSArrayController - Dynamic Class?
Not exactly. Sorry I've done such a poor job describing what I'm after.
I've got an entity named Building (and also entities named Floor and
Room). Each of these entities has an index attribute, which is an
int16 type. All three entities inherit the index attribute and others
from a common parent, which I'm calling IndexedObject. The UI has
tables for each entity and '+' and '-' buttons to add and remove
entities from the table and drag-and-drop to reorder the entities.
The '+' button is linked to the NSArrayController subclass' add:
method, which automatically invokes insertNewObjectForEntityForName:
inManagedObjectContext:. I've been using:
- (void)addObject:(Building *)object {
[super addObject:object];
object.index = [NSNumber numberWithInt:[[self arrangedObjects]
indexOfObject:object]];
NSLog(@Added %@, [object description]);
}
to override NSArrayController's standard implementation and assign an
index to the newly-created object, based on its index within the
underlying array. The problem is the type for the argument in the
method declaration. With the standard method signature:
- (void)addObject:(id)object
the runtime doesn't have a specific entity to look to for a
definition, so it doesn't know that I really want to be adding a
Building entity, which does have an index attribute, and it throws an
error. If I change the method declaration to:
- (void)addObject:(Building *)object
it knows that the Building entity has an index attribute, so the error
goes away. But, that means that I need to create separate
NSArrayController subclasses to control the arrays of the Floor and
Room entities. I'm hoping to find a method declaration that can look
to the entity type of the objects that the array controller is
controlling (as set in IB), so that I can use the same subclass for
the Building, Floor and Room arrays.
Having separate NSArrayController subclasses for Floor and Room isn't
the end of the world, but if there's a cleaner way to do this, I'd
like to learn about it.
Thanks for all of your help.

Oh, I get it now.
The error you're getting is nothing to do with the runtime. The type
of the parameter variable is a compile time matter only.
If IndexedObject is the superclass of Building, Floor and Room, you
can take care of this at compile time:
- (void)addObject:(IndexedObject *)object {
[super addObject:object];
object.index = [NSNumber numberWithInt:[[self arrangedObjects]
indexOfObject:object]];
}
If it's just an entity with no custom class, you have to just make the
compiler stop complaining:
- (void)addObject:(id)object {
[super addObject:object];
[object performSelector: @selector (setIndex:) withObject:
[NSNumber numberWithInt:[[self arrangedObjects]
indexOfObject:object]]];
}
Either way, you only need one NSArrayController subclass for all 3
cases.
If you wish, you can add a check that the passed object is of the
correct class or entity.
Incidentally, it would be slightly more correct to use NSNumber
numberWithUnsignedInteger -- because indexOfObject: actually
returns a NSUInteger value, which is unsigned, and which is 64 bits in
a 64-bit app. This is not going to be a problem unless you have more
than 2 billion objects, but it's good to be prepared. :)

With @selector, the method name still doesn't change, but the refactor window does give a warning that it's not going to change automatically.

Re: Loading GC test bundles
GC is opt in on a per-process rather than per-binary basis. Thus in order to load a GC bundle, OCRunnerTool needs to be built at least GC-supported and running under GC. You'll need to determine in advance whether to run tests GC or not, and then invoke OCRunnerTool with the appropriate environment variable set to disable GC when not. -- Chris On Jul 18, 2009, at 8:18 AM, Martin Pilkington pi...@mcubedsw.com wrote: Hi, I'm the developer of a GUI for OCUnit called OCRunner.

I've looked around but the only thing I've found relating to OCUnit and GC is something about framework tests running with GC required not being supported in Xcode 3.0.

Re: Where to release in UIView
That actually is a valid concern; since you're on the iPhone, memory constraints are tight, and your view may actually be unloaded at some point. Instead of doing additional initialization in awakeFromNib, (which has no counterpart), I'd recommend doing your additional setup in viewDidLoad: on the associated UIViewController. Then, in viewDidUnload: you can release anything you instantiated in viewDidLoad:. Note that viewDidUnload is only available in iPhone OS 3.0 and later. -BJ On Sat, Jul 18, 2009 at 1:56 PM, DKJ hatzicw...@shaw.ca wrote: Thanks to all who replied.

Yes, it's more sensible.
But now that I think about it, the performSelector approach has one
*slight* advantage to the developer. If you ever use Xcode's refactoring to
change the name of the property, it will miss the property name in the
string. With @selector, the method name still doesn't change, but the
refactor window does give a warning that it's not going to change
automatically.
Perhaps the best option is option (c): create a IndexedObject abstract
superclass (if there isn't one already) and use 'object.index = ...' after
all.
In order to preserve the contract of NSArrayController (which is that you
can add *any* object with addObject:), I'd recommend doing something like
this:
- (void)addObject:(id)object {
if ([object respondsToSelector:@selector(setIndex:)] {
object.index = [NSNumber numberWithInt:[[self arrangedObjects]
indexOfObject:object]];
}
[super addObject:object];
}
Note that I call super's addObject: at the end. I have no idea what the
implementation of NSArrayController's addObject: is, but it's always better
to have things set up before you pass something along to super. Imagine,
for example, that NSArrayController writes the object immediately to disk
when added. Since you haven't set your index yet, it would be incorrect.
(I don't think it actually writes anything to disk at that point, but you
get the idea.)

Re: Core Data design patterns

Throughout my application I have to do fetching. I have simplified
my code by making a helper class called CoreDataHelper...
In fact, I can think of another variation of my method. Namely, to
not have class methods in CoreDataHelper, but rather instance
methods and initialize the CoreDataHelper with the MOC. The
advantage of this would be that I would not have to pass the MOC
into each method call. The drawback is that I have to create a
CoreDataHelper instance each time I want to use its methods.
This is what I've done, except I've taken it a step further. I've
created helpers like this for several different entities. Each entity
is a subclass of SSYMojo. SSYMojo has a moc and an entity. See my
@interface for SSYMojo below.
A third variation would be to simply do either of the two variations
above, but not pass in MOC anywhere and instead just use [[NSApp
delegate] managedObjectContext] whenever I need it within
CoreDataHelper.
I don't think you want to do that because all ^real^ Core Data apps,
sooner or later, end up having multiple mocs.
A more general closing question: How do you make your code more
organized? ... Any antidotes?
I believe you mean anecdotes.
To avoid disorganized code, sit down with a pencil and big piece of
paper, or a diagramming tool like OmniOutliner, and draw some class
diagrams and flow charts. I've heard that some people even do this
before they start on a project :)) The Holy Grail is to write a
software specification which lays out everything so perfectly that you
can hand it to a chimpanzee to write the code. In practice, there's
always alot of back-and-forth between the spec and the code, and in
the interest of getting the job done before the market moves on,
you'll tend to write specs and diagrams for the more difficult parts,
but just write code for the easy parts that you've had prior
experience with. It's always a tradeoff between spending the time up
front to plan and diagram, versus the risk of having to go back and do
it later and rewrite code if your intuition turned out to be
insufficient.
Maybe reading some good design principles book will help?
Great.
Or getting a degree in CS?
Wonderful if you've got the time.
How did you guys learn this stuff?
The hard way, except it's not learn, it's learning ;)
