I'm currently setting up this view to be swapped with another in an iPhone game. When I use this code... - (void)viewDidLoad { menuViewController = [[menuViewController alloc] initWithNibName:@"SomeViewController" bundle:nil]; self.menuViewController = menuViewController; [self.view insertSubview:menuViewController.view a...
Alright, I'll try to explain this the best I can. I have an iPhone app and it has a text field which the user can only input Numbers. Not a problem there. However, there is no done button on the numpad, so I can't make it disappear. I could make a button that the user presses to dismiss the keyboard, but I'd rather have a done button...

So how...

I have a UIWebView in my app that shows some html-formatted text (loaded from a .plist file from my bundle). The UIWebView takes about 1 second to render the text on the screen and during that second the whole UIWebView is white.

Hi, I'm developing a CoreData non-document-based app. The SQLite store size is regularly of order ~60MB, and it's cumbersome that Time Machine backs up the entire database once per hour. Is there a way to make Time Machine back up only the changes? I'm thinking of abusing the CoreData external records API for spotlight and let the mach...

I am trying to create a UIBarButtonItem that looks like the normal Apple ones, but I'd like to include an image and a piece of text. As far as I can tell, you can't specify both an image and a title (the image shows but the title doesn't if you set both). Also, if you use a customView, then you lose the BarButtonItem look and feel. Wh...
I'm trying to get a NSString broken into lines to fit a desired width (as it would happen inside sizeWithFont:constrainedToSize:). Is there a better way to do this than guessing where the breaks would happen in sizeWithFont? ...

Let's have one project idea per answer. If you have multiple ideas to suggest, post multiple answers. It'll help for you to also list what Cocoa concepts your pr...
Is there a way for xcode to launch an application with an app URL? I've read the answer to this question http://stackoverflow.com/questions/1239000/debugging-app-when-launched-by-push-notification, and it works great for single tests. I'm trying to write unit tests for launching the app with lots of different URLs, and using the previo...
Are there any standard objects or functions to parse an NSURL's components? Clearly I could write one, but why re-invent the wheel? [NSURL path] will return an NSString like "argX=x&argY=y&argZ=z" What I would rather get back is a dictionary populated with {@"argX" => @"x", @"argY" => @"y", @"argZ" = @"z"} For the path, which returns ...

Sorry for long description, however the questions aren't so easy... My project written without GC. Recently I found a memory leak that I can't find. I did use new Xcode Analyzer without a result. I did read my code line by line and verified all alloc/release/copy/autorelease/mutableCopy/retain and pools... - still nothing. Preamble: St...
I have an array of CGPoints (basic struct with two floats: x and y). I want to use OpenGL ES to draw a textured curve using these points. I can do this fine with just two points, but it gets harder when I need to make a line from several points. Currently I draw a line horizontally, calculate its angle from the points given, and then ro...
Hi, well the question is the one I put in the title: "Should I define overloaded inherited method in the header file in ObjC?" Thanks UPDATE: I was wondering this because I will make my project's documentation using Doxygen, and maybe is better to declare overloaded inherited method because of the documentation. For example for method ...
Hi, I was designing a class and I realize that I've got several methods that the only parameter they have is the output parameter for errors. The problem is how should I name this methods, because they can get very confusing. I've been reading the Apple's Code Guidelines and it saids nothing about this. Here is an example: -(BOOL)loginE...
