Going through the Game Center / GameKit docs, I could not find any information on specifying game configuration variables for a match. Let's say that you want to specify certain features a match should have to qualify for match making (e.g. you want to exclude certain weapons from the game, want to specify a length for the match etc.). ...
Hey Guys, So I have a simple split view that functions great except when the view loads. For some reason if it loads in landscape mode, it only loads on ~half the screen (it seems like it is the width of the portrait mode). Does anyone know what may be causing this behavior? I am using the default split view controller provided by th...

I am trying to achieve an effect similar to the globe of the ABC News iPad app. (Google Images Examples) Is it possible to get this effect by transforming CALayers?

Hi all, I'm trying to use the Skype SMS URI from an iOS (iPhone/iPod Touch) app, i.e. opening the skype:+33123456789?sms URI.

However, it fails miserably on the iPh...

Guys, I am a newbee for iOS. I need to create dynamic layout since the GUI will be generated according to the data. I checked the UIView references, it seems the standard way to add subview is like: CGRect rect = CGRectMake(0, 0, width, height); UILabel *label = [[UILabel alloc] initWithFrame: rect]; [someView addSubView: label]; But...
I have an error similar to the one in this post. Now, I'm sure I've made some stupid error somewhere, probably related to releasing an object or an observer or what-not, but since I can't seem to find a way to debug the code I thought I could use the NSDebugEnabled, NSZombieEnabled and MallocStackLogging (as shown here). Can it be done...
I have to do this: 1:CGRect originalSubviewFrame = subview.frame; 2:view.frame = (CGRect)newFrame; 3:subview.frame = originalSubviewFrame; I think instructions 1 and 3 shouldn't be there but if I don't restore the subview shape, it change for some reason!?!? I read the documentation but it's unclear. ...
I am trying to have some controls appear when you push a button and have it disappear when you press a different button. Right now the HUD is comprised of an image view, and some custom buttons in a UIView called "credits". I've managed to have it disappear using: [credits removeFromSuperview]; How do I have it reappear? ...

I'm working with some Core Animation for the first time and in the process of implementing a playing card that I can flip around, I've decided to use a CALayer to display the contents (not sure how I'm going to get two sides, but that's another question) and I need to be able to flip it over, move it, etc...

I'd like to use iOS device as a TCP client, but I can't find an understandable API/guide/sample of how to do that. I tried SimpleNetworkStreams and PictureSharing, but they are both using Bonjour.
