delegate dealloc in NSToolbar customItem
Hello all, I have an issue that is giving me some serious trouble. I have a NSPopupButton in a NSToolbar, this button has a menu which has the windowController as its delegate. everything works fine until I try to edit the toolbar, when I do that the items encode with an NSArchiver and the the original object is dealloced. The problem is that my delegate is also getting dealloced for some reason. Has anyone had this problem before? did you find a way around it?

Touchscreens and control scaling
Hi list, I've been sketching out an application and could do with a little advice on which cocoa-direction to take. It's a full-screen (kiosk) type app, running in a very controlled environment (not for wide release) but which would run on an external touchscreen monitor. While I can make buttons and labels big enough for fingers to poke, I'm concerned about controls like table headers and scrollers being large enough to make finger-size targets. I'm asking sooner rather than after testing the usability in case there are special considerations I should take before writing the first lines of code. The only options I can think of are: 1. Make a normal app and use quartz debug to scale *everything* up 2. Subclass and/or redraw any controls too small for finger taps 3. Shut up and try it out first In the absence of UIKit for desktop macs, does anyone have any suggestions as to the direction an app like this should take?

RE: Detecting when fetch: finishes
Let me explain what I'm trying to do by referring to iTunes. Imagine that iTunes has only one underlying NSArrayController and only one table view in the UI. And image that when you click on a smart playlist, all that happens is that new fetch predicate is set for the underlying array controller (and column layout sorting of the table view changes). This results in the problem of the table displaying BEFORE the fetch predicate actually executes (in the next runloop iteration). This results in the user visually seeing on screen the fetch results changing (which I don't want). What I would have wanted to do is to, perhaps, hide the table view for a brief moment while the fetching completes. I can easily hide it within the outlineViewSelectionIsChanging: delegate method. But, as we know by now, there is no way to know when to unhide the table view again; in other words, no way to know when the fetching with the new fetch predicate completes. How would you get around this problem?

KVO and master-detail NSTableViews
I'm getting flaky behavior from my KVO code and I'm wondering what I'm doing wrong. I can't find any similar examples. I have a pop-up button and 2 NSTableViews. The pop-up button selection controls the content of the left NSTableView. The left NSTableView's selection controls the content of the right NSTableView. The pop-up button and NSTableViews are bound to separate NSArrayControllers. Each NSArrayController is bound to a separate NSMutableArray property in my app controller. My app controller observes selectionIndex in the pop-up button's NSArrayController and selectedObjects in the left NSArrayController. On startup, the pop-up button is populated, which causes a call to observeValueForKeyPath:ofObject:change:context:. This sets the left NSMutableArray, which in turn causes another (nested) call to observeValueForKeyPath:ofObject:change:context:, which sets the right NSMutableArray. There seems to be a race condition -- sometimes the left table view is populated, sometimes the right, sometimes none. Each time I edit the nib, the behavior changes. Is this a bogus way to implement the dependent NSTableViews? What's the right way?

NSNull and distinct objective-C type
Hi folks,
I need some advice on how best to handle an itchy problem. In order to
tighten up my coding I'm compiling with warnings as errors which has
showed up a big problem with my code.
I have a tableView using a datasource array of dictionaries. Fairly
standard stuff. 2 of the keys in this dictionary are credit and
debit. When I process the data only one of these can be set, the
other has to be nil or NSNull. I test against this later on when
manipulating the data. My problem appeared when I I turned on warning
as errors. I kept getting the following;
if ([amount floatValue] 0){
NSString *amountString = [[amount stringValue] substringFromIndex:1];
debit = [NSDecimalNumber decimalNumberWithString:amountString];
credit = [NSNull null];
warning: assignment from distinct Objective-C type
} else {
credit = amount;
debit = [NSNull null];
warning: assignment from distinct Objective-C
type
}
}
I thought I'd be smart and change the NSNull to nil instead but of
course that terminates the dictionary early when I come to create it.
NSMutableDictionary *transdic = [NSMutableDictionary
dictionaryWithObjectsAndKeys:date, @date, memo, @memo,
transferIndex, @transferIndex, credit, @credit, debit, @debit,
nil];
I'm getting the error because I initially declared my credit and debit
objects as NSNumbers. Can I recast them without them losing scope?

You can not assign null to an NSNumber, NSNull is of another type.
You could of course change the variabletype of credit to id instead
of NSNumber, then the NSNull would work. It doesn't change much at
all, the compiler replaces your NSNumber with id anyway. It just
allows you to use NSNumber for static type checking.

XIB and AppleGlot

My app is starting to use XIB files. These get compiled into NIBs in My.app. The AppleGlot docs seem to say I should put My.app 2.0 into _NewBase, and My.app 1.0 into _OldLoc. When I do that, the nibs that came from xibs are ignored (my.app.wg doesn't contain any of the strings from those nibs). If I put NewDialog.xib into my.app, I see its strings in the .wg. It seems like I be putting the source code form of the language.lproj folders into _OldBase, but none of the docs say that. Can someone point me at a discussion of how to use AppleGlot in the presence of XIB files?

Re: launchd detecting when an application is running
Tom Hohensee wrote: I have written an application that I would like to launch whenever a certain app is launched.

How soon after the original app launches do you need to start the secondary app? How much control do you have over the original app? Can you replace the original app's existing executable with another one that triggers your secondary app, then goes on to exec the original executable? The trigger could be many things, including something that launchd monitors (see 'man launchd.plist' for on- demand conditions). Maybe run a daemon that monitors FSEvents for creation of a temp-file you know the original app will create. Maybe on-demand monitor the original app's user-defaults, so launchd triggers that way.

I have a pop-up button and 2 NSTableViews. The pop-up button selection controls the content of the left NSTableView. The left NSTableView's selection controls the content of the right NSTableView. The pop-up button and NSTableViews are bound to separate NSArrayControllers. Each NSArrayController is bound to a separate NSMutableArray property in my app controller. My app controller observes selectionIndex in the pop-up button's NSArrayController and selectedObjects in the left NSArrayController. I think you're manually using KVO when you could (and perhaps should) be using bindings. I also think you're setting up the observations in the wrong direction. I wouldn't have the app controller observe properties of the array controller. Mediating controllers should bind to (thus, implicitly observe and set) properties of the coordinating controller (or the model, reached through the coordinating controller). First, I don't know if you need the array controller for the pop-up to manage the selection. I think you should bind the pop-up's selectedObject to a (possibly new) property on the app controller. This may require use of both the content and contentObjects bindings of the pop-up to get selectedObject to be an appropriate object. Second, I think the array controller for the left table would bind to or through this property (the one bound to the pop-up's selection) on the app controller. Lastly, the array controller for the right table would bind through the selection property of the array controller for the left table. Put another way, bindings are meant to reduce or eliminate glue code. You seem to be reproducing the sort of glue code that one would typically have in the pre-bindings days, just using KVO (and maybe bindings themselves) to trigger the glue code.

Re: Help with SHA class
I wrote a SHA class using the algorithm at http://en.wikipedia.org/ wiki/SHA1#SHA-1_pseudocode and while it runs without crashing, the hashes it produces are not the same as those from numerous online SHA-1 hashing converters. Of particular confusion is the issue of byte swapping and how that might affect the rotation/addition operations within the block hashing method. I'm clearly doing something wrong, but after several days of trying, I haven't been able to get the hashes to match online examples. Why are you writing this algorithm? Googling these keywords: sha1 public domain shows numerous hits. Since public domain means no license, I don't see why you'd want to reinvent this wheel, especially given the known weaknesses of SHA1. If you're writing it in order to learn about hash algorithms, then I think it makes more sense for you to debug your code yourself, as unhelpful as that may seem to be. I also suggest reading sources other than Wikipedia, not necessarily because Wikipedia might be wrong or have a typo, but because there might be more detailed step- by-step explanations elsewhere on the web. Or look at the public domain ones and see how they differ from yours. You might also try running your code on a machine that's actually big- endian, to see what happens. Unless you already are. Iff you're running it on an Intel CPU, simply compile the code for ppc and use the 'arch' command to run that slice instead of the native slice. If it doesn't produce the same output, then you have an implied-endian bug. If it does produce the same output, you still have a bug. If you're using an Intel CPU, maybe try finding a little-endian implementation of the algorithm. BTW, your code should probably be using the type names UInt32 and UInt64, instead of making assumptions about sizes. There are also places where you use the constant 4 instead of sizeof(UInt32). Though these may not affect this implementation, they seem questionable to me. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSNull and distinct objective-C type
Hello All,
I am facing an issue in use of mach_absolute_time().
mach_absolute_time() gives drift even when NTP timing update is on.
Please see my code below:

{
uint64_t nowTime = mach_absolute_time();

{
sleep(5);
uint64_t current_Time = mach_absolute_time();
uint64_t differenceTime = (current_Time - nowTime)*1E-6;
drift = differenceTime - (i+1)*5000;
NSLog(@Elapsed Time =%lld,differenceTime);
NSLog(@drift =%lld,drift);
}

delegate:self];
if (connection == nil) {
//connection couldn't be created!
NSLog(@Connection couldn't be created: %@, [newReq URL]);
[self startSyncAfterTimeInterval];
}
The first request works, after that it seems to not even send the request,
although the server is still responsive! I get the following error:
*Connection failed with error: Error Domain=NSURLErrorDomain Code=-1001

Your expectation is wrong. sleep() will sleep for 5000 milliseconds.
But (1) there's no guarantee that your thread gets to run at the
5001st millisecond, and (2) your timing and printing code itself takes
non-zero time.
If you really want to run every 5000 milliseconds with no drift,
you'll need to use a more careful sleep mechanism (starting with
nanosleep() plus accounting for the non-sleep time). A proper timer
like NSTimer or CFRunLoopTimer might also work; they won't drift, but
their jitter might be too high for your purposes.

While I can make buttons and labels big enough for fingers to poke, I'm concerned about controls like table headers and scrollers being large enough to make finger-size targets. I'm asking sooner rather than after testing the usability in case there are special considerations I should take before writing the first lines of code. The only options I can think of are: 1. Make a normal app and use quartz debug to scale *everything* up 2. Subclass and/or redraw any controls too small for finger taps 3. Shut up and try it out first I don't think option 1 will work well. Apple hasn't done too much to make anything resolution independent. Try running stuff on a non-1.0 scale factor to see. We ended up going with option 2, partially for usability, and partially because we wanted an entirely themed kiosk environment anyways. For a kiosk, you should definitely consider your own UI. That's what I have done. You'll also find that if your app will be exclusively used in touch environments, some of the Aqua controls may not fit well at all (since they were designed primarily for point-and-click). (Same thing goes for iPhone OS UI; totally different set of controls and behaviors). In terms of resolution independence, note that while Apple's own Cocoa controls may not yet be RI-ready, the underlying frameworks are basically all there. I actually submitted an app for the design awards back in Tiger days that was RI-savvy. It not only worked with integral scale factors, but the fractional values as well. ___ Ricky A.

Re: launchd detecting when an application is running
Thanks for the replies. I am actually quite familiar with launchd but was thinking that maybe I had missed something. I vaguely remember reading a blog where someone had used launchd to detect the app launching event but for the life of me I cannot find it. It probably had something to do with detecting file changes of the launching app. Unfortunately, the app I want to monitor is a commercial app which is not mine and I am not aware of any temp files it creates or files it alters. For the time being I have written a small background app using NSWorkspace to detect the event, but I find it a waste of resources especially since the program it starts is only used for a brief period of time. I probably will not incorporate it into the final release. Also, thanks to Kyle for pointing out the launchd IPC reading on the launchd man page. I have must have scanned that page several times but never really paid much attention to that statement.

How soon after the original app launches do you need to start the secondary app? How much control do you have over the original app? Can you replace the original app's existing executable with another one that triggers your secondary app, then goes on to exec the original executable? The trigger could be many things, including something that launchd monitors (see 'man launchd.plist' for on- demand conditions). Maybe run a daemon that monitors FSEvents for creation of a temp- file you know the original app will create. Maybe on-demand monitor the original app's user-defaults, so launchd triggers that way. Those are just some random ideas. It might help if you described exactly what you're trying to accomplish, including what the original app is. Describe the problem; don't propose a solution.

NSToolbarItem bindings crash
I have an NSToolbarItem with its Enabled binding set to a property in a controller object. For some reason after customizing the toolbar the next time the property is updated a notification is sent to a deallocated instance of the NSToolbarItem. It does not matter if I change the item at hand or another toolbar item. The crash takes place the very next time the bound item's property is updated. Is there something I am supposed to do to maintain the bindings of toolbar items created in IB? Have I made a bad assumption, that the bindings would be maintained for me?

I also suggest reading sources other than Wikipedia, not necessarily because Wikipedia might be wrong or have a typo, but because there might be more detailed step- by-step explanations elsewhere on the web. Or look at the public domain ones and see how they differ from yours.

You might also try running your code on a machine that's actually big-endian, to see what happens. Unless you already are. No access to a big endian machine Iff you're running it on an Intel CPU, simply compile the code for ppc and use the 'arch' command to run that slice instead of the native slice.

If you're using an Intel CPU, maybe try finding a little-endian implementation of the algorithm. No luck on that front. BTW, your code should probably be using the type names UInt32 and UInt64, instead of making assumptions about sizes. There are also places where you use the constant 4 instead of sizeof(UInt32).

Should touch events related to a given view be implemented in the view or the view controller?
Previously, I would have said the view-controller. But I just finished looking at the Metronome sample, which is included in the iPhone SDK. The touch handling code as well as some of the view initialization code (requiring a completely loaded view) is implemented in the UIView-derived class. Is this a bad example of how things should be partitioned or do I have the wrong idea about what the view-controller is for? Here are some related follow-up questions: 1) What should be implemented in the view-controller? 2) Should all of the view properties be completely setup and configured within the view's own init and awakeFromNib methods or is the intent of viewDidLoad to allow for configuring view properties before proceeding? Yeah, I'm confused. Please discuss.

Make an NSArray ivar, which you add the connections to. This will work under GC or retain/release. GC works because there's a reachable reference to the NSArray, which contains reachable references to the NSURLConnections. R/R works because adding any object to NSArray calls retain() on the object. If you don't want the NSURLConnections to live indefinitely, you'll have to occasionally cull the dead ones from the NSArray. -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Not sure I understand the question but as a guess...
Put them in an NSMutableArray or NSMutableSet if you need to keep

a pointer to the connection sending the delegate message.
This is exactly what I did as shown in the code snippets below.
connections is a class instance of an NSMutableArray. Does this seems
correct? What's so weird is that I get a log on my HTTP server that the same
URL is being called twice!

[newReqGet setHTTPMethod:@GET];

How does one use AppleGlot and XIBs?
I have an app, My.app, that was previously localized. I'm working
on version 2.0.
My app is starting to use XIB files. These get compiled into NIBs
in My.app.
The AppleGlot docs seem to say I should put My.app 2.0 into
_NewBase, and My.app 1.0 into _OldLoc.
When I do that, the nibs that came from xibs are ignored (my.app.wg
doesn't contain any of the strings from those nibs). If I put
NewDialog.xib into my.app, I see its strings in the .wg.
It seems like I be putting the source code form of the
language.lproj folders into _OldBase, but none of the docs say
that.
Can someone point me at a discussion of how to use AppleGlot in the
presence of XIB files?
And (if it's not covered by default): What to do when the previous
shipped app had a non-compiled Foo.nib, and the about-to-ship app
has Foo.xib in the souces, and thus a compiled Foo.nib in the built
app.
Hey Eric -
I believe the file names in _OldBase, _NewBase, and _OldLoc need to
match. It sounds like your files in _OldBase and _OldLoc are
probably .nib files, but you're files in _NewBase are .xib files.
You can upgrade the files in _OldBase and _OldLoc to .xib files with
something like this:
cd _OldLoc
find . -name *.nib -type d -exec ibtool --upgrade {} \;
cd _OldBase
find . -name *.nib -type d -exec ibtool --upgrade {} \;
Hopefully that addresses you're problem -

Re: Should touch events related to a given view be implemented in the view or the view controller?
Hey Michael - It might help to approach this problem with the idea of If I had multiple view controllers using this view, how would I make that work best. Event handling is something you would normally manage at the UIView layer. After those events are handled, they're typically translated them into some sort of action, or delegate callback. The delegate call back that builds further meaning belongs in the view controller, but the event capturing and translation into some meaningful gesture should go in the view. UIButton for example tracks a touch and delivers an action. It's up to the button to track the touches, and a controller to receive the action and ascribe some meaning to it. If you're view is completely generic, and you want to customize a specific instance of it for one view controller, then you should place your view customizing code in you're -[UIViewController viewDidLoad] override. If your view would want these customizations no matter what controller it was working with, you should place them in the view's awakeFromNib method. Good Luck - Jon Hess On Jun 4, 2009, at 3:45 PM, Michael A. Crawford wrote: Previously, I would have said the view-controller. But I just finished looking at the Metronome sample, which is included in the iPhone SDK. The touch handling code as well as some of the view initialization code (requiring a completely loaded view) is implemented in the UIView-derived class. Is this a bad example of how things should be partitioned or do I have the wrong idea about what the view-controller is for? Here are some related follow-up questions: 1) What should be implemented in the view-controller? 2) Should all of the view properties be completely setup and configured within the view's own init and awakeFromNib methods or is the intent of viewDidLoad to allow for configuring view properties before proceeding? Yeah, I'm confused. Please discuss.

Validating a NSSegmentedControl in a toolbar
I'm having problems validating an NSSegmentedControl in a toolbar. I have tried implementing both -validateUserInterfaceItem: and - validateToolbarItem: but neither is called for the segmented control. They are called for other simple buttons in the toolbar. There's a note in the documentation for -validateToolbarItem: that NSToolbar only calls this method for image items, which might explain it. So what do I need to do to make this work for the segmented control? I've read all the toolbar and validation documentation I can find but I'm none the wiser - nothing so far stands out as the obvious right way to proceed. My toolbar is currently wholly set up in IB, with no code in my app at all. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to animate an object in a circle, but preserve it's orientation
Thanks for the quick response! I've mostly been reading trying to see what would work. I did mess with changing the anchorPoint to get the initial animation route, but that didn't seem to suffice. The object I'm animating is a simple UIView containing an image. I thought about the timer approach like you mention, the reason I shy'd away from it was that it needs to stay in sync with another animating object (in my ferris wheel example this would be the wheel itself.) But now that I think of it I might be able to use the timer to animate that as well so they do stay in sync. Does that seem like the best and/or easiest approach?

Re: How to animate an object in a circle, but preserve it's orientation
On 05/06/2009, at 1:48 PM, Miles wrote: Thanks for the quick response! I've mostly been reading trying to see what would work. I did mess with changing the anchorPoint to get the initial animation route, but that didn't seem to suffice. The object I'm animating is a simple UIView containing an image. I thought about the timer approach like you mention, the reason I shy'd away from it was that it needs to stay in sync with another animating object (in my ferris wheel example this would be the wheel itself.) But now that I think of it I might be able to use the timer to animate that as well so they do stay in sync. Does that seem like the best and/or easiest approach? Well, I'd say it can be made to work, but I personally wouldn't do it this way. It's still a bit vague, but I'm visualising a Ferris Wheel with a number of (one or more) attached basket objects. To model this, I would define the angle and radius as properties of the wheel, and the position of the basket as a property in terms of its position relative to the wheel (a fixed angle, say). The basket objects could be owned by the wheel, which makes good sense to me. To animate the rotation of the wheel, simply increment the angle of the wheel. This in turn directly or indirectly updates the positions of its attached baskets. The whole thing is then redrawn in the new position. The absolute location of a basket can be simply calculated as needed when the basket is drawn, based on the wheel's angle, radius and relative position of the basket on the wheel. Any time I hear people talking about keeping things in sync alarm bells ring. Instead, make one property a derivative or dependency of the other, then there is nothing to 'sync', it's always in sync. In terms of visualising the wheel/basket model in a view, I'd just use a custom view and drawn the entire content. The wheel object could draw itself, which in turn calls on each of its basket objects to draw themselves, and so on. Trying to make each basket a separate view will be inefficient and more complicated than this. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: How to lock an object?
It's not just password. It can be any thing which is secure. Like file data, personal information, any thing user mark it as secure.

Re: How to lock an object?
On Jun 4, 2009, at 8:57 PM, cocoa learner wrote: I am writing an application which read an encrypted data from disk, decrypt it and display that in UI. Now the object that holds that decrypted data should not page out to swap area (for security reason). This is my need. Is there a better way to do this? If an attacker can get to the swap files, that means one of two things: (a) they have (or had) superuser on the machine (b) the attacker has physical possession of the machine (which has been rebooted or powered down; see (a)) If (a), you've already lost. With superuser, the attacker can capture events, inject code, commandeer the window server, and/or p0wnz3 your process just about anyway they want. So, really, you are defending against (b). In the case of (b), for defending the swapfile to even matter, there must be no other decrypted bits on disc anywhere else.Go that? Assuming you do, then the easiest way to secure the swapfile is to turn on swapfile encryption. Actually, it might be the only reasonable solution. There is no way you are going to be able to mlock() all of the random allocations associated with any particular sub-graph of objects in your application. The allocations are an implementation detail and may change at whim of update, architecture and/or OS release. You might be able to lock down your entire process, but that would be exceptionally rude as it is going to take away significant resources from other applications and, on a particularly resource constrained system, could lead to exhaustion of memory resources entirely. b.bum ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
