I am using SenTest in XCode for my unit tests. I must run a command-line task for my unit tests to test. I can do that in the +initialize method of my test class (subclass of SenTestCase, of course). I would like to terminate the command-line task when the tests are done. Since there's not an opposite of +initialize, I'm stumped. Is th...
I don't develop in XCode very often, and recently MacPorts told me I needed to get 3.1 in order for a package to work. I went to apple, and they offered me the latest version, which turns out only to work for OSX 6. Since I have OSX 5, it doesn't help me any. Is there any way to get xcode 3.1.* from apple at this point? ...

I've been following a tutorial using Cocos2d and I've been learning a lot. I got to the part inserting a "Game over" bit. Previously it would just NSLog "You lose". I went over to a different project and started something else. Then I came back and removed the NSLog line and changed it for the GameOverScene (replaceScene). However, ...

I have an iPhone app that I would like to port over to the iPad, but I would like to have as little duplication as possible. How do people usually go about doing this? In xcode can you have different targets for iPhone and iPad and perhaps do some pre-processor checks? Or is it best to simply have two separate projects altogether? Not...

Hi. Being new to Xcode and Objective-C I find it hard to get my head around the Interface builder and Objective-C when doing things that are following the basic pattern. I have created a subclass of UIViewController that I want to instantiate several times to make a grid with each row being controlled by an instance of this class. So the...
Hi. What is the best way to handle this situation on an iPhone device: My program ramps the pitch of a sound between two values. A button pressed calls a method that has a while loop that does the ramping in small increments. It will take some time to finish. In the meantime the user has pressed another button calling the same method. No...
