I'm finding a few open source projects, mostly older, that lack an .xcodeproj directory hierarchy. It seems like all other crucial files are there. Curiously enough, I'm wondering how these projects are even accessed via Xcode? I'd like to compile them, break them, fix them etc. Is there a way to open these more legacy projects? Here'...
I'm working on an iphone app that needs to display superscripts and subscripts. I'm using a picker to read in data from a plist but the unicode values aren't being displayed corretly in the pickerview. Subscripts and superscripts are not being recognized. I'm assuming this is due to the encoding of the plist as utf-8, so the question ...
Greetings everyone! I have a function that has an array pointer passed it to modify stuff in an array: (void) arrayFunction:(Byte[])targetarray { // do stuff to targetarray } It's an array of type Byte, but I don't think that I've put the right thing in the round brackets. What should it be instead of (Byte[])? There may be several...

I am playing MP3 audio via a URL using the MPMoviePlayer. But when it plays, it flips to Landscape layout, and I would like it to remain in portrait layout. Any ideas? Thanks, John ...
I am streaming an MP3 file using MPMoviePlayer, and I would like to have an image displayed instead of the default Quicktime logo in the background. I found out a way to have an image overlay the player, but the problem with that, is you have to tap outside the image to get the player controls to appear. And when they do appear, they a...

The array controller contains Core Data objects that have a "name" field. I have setup the NSSearchField like this: Bind To: the array controller Controller Key: filterPredicate Pre...
I am trying to set an image as the background of a custom UIButton. I was able to set a background image for the "rounded rect" UIButton in interface builder, but now the borders have vanished. Is there any way to retain the borders? Also, I would like to make the borders show up rectangular instead of rounded. ...
I have a mac mini on which I do some iphone and other experimental development. It is hideously slow to build some of the larger projects I have tried out (like 3d engines and such). There are some support for distributed builds with distcc and I have a quad core linux box just standing idle beside it. The question is: is it possible to...
I thought I had a pretty good handle on memory management for objective-c, but I can't figure out the following situation: @protocol MyProtocol @end @interface MyObject : NSObject { id<MyProtocol> reference; } @property (nonatomic, retain) id<MyProtocol> reference; @end @implementation MyObject @synthesize reference; -(vo...
In iPhoneOS, I want to create a UITabBarController for global app navigation (like the 'Phone' app and many others) whose tabbar items have text labels, but no icons. I would therefore also like the height of the tabbar to be much shorter. The tabbar should only be tall enough to accomodate the text labels or Apple's minimum recommende...

So, a long long time ago I used to program procedurally initially with Basic on my first BBC Model B and then a small amount of Pascal at university as well as assembly along the way. Then along came OO which seemed much more sensible all round and that was all I used with C++, Perl, Java, Ruby..... Coming back to programming non web s...
Hi there, I've got an iPhone app I'm developing and when the app launches I open an SQLite database connection, and I close it when the application terminates. The database is correctly in the applications documents folder. During the lifetime of the app I run several INSERT and UPDATE statements. However, for some reason my UPDATE sta...
I am using a UIWebView to display HTML formatted text. I am not loading a webpage, just supplying a string of HTML to the UIWebView. Now I want to animate this UIWebView on screen, actually several of them (2-10 at a time). UIWebView is a little heavy, and although I haven't attempted it yet, I am planning for the worst. (I don't think...
I made a little library for the IPhone that I would like to redistribute, but I cannot find how to compile it to work on both the simulator and the iphoneos. I know there is a way to build a lib.a for both architecture, but I cannot figure it out. ...
I am wondering what kind of methods are "helper methods". Where do we have to draw te border to say that an specific method is a "helper method"? Actually, I consider any method to be a "helper method" if it's not an initialization method, a method implemented for conforming to an protocol or delegation response methods. Any other method...
I need to get bitrate information from audio files, for some reason AudioFileGetProperty function with kAudioFilePropertyBitRate constant always returns 0 for me. The same with kAudioFilePropertyInfoDictionary, the resulting dictionary doesnt contain bitrate info. I would try to manualy get this from raw data in case of mp3, but I need t...
