I need the name of the class that owns a method, as NSString. Example: There's a -fooBar method inside a SomeClass, and that -fooBar method runs some code. This code must print out what class "owns" it, I mean: What class that method belongs to. So I can't hard-type the class name in a NSString because I need that for debugging purposes,...
Hi everyone, I am trying to find my way into Obj-C for iPhone programming using this tutorial. In the end, what ever menu point you choose, SubViewOne was displayed. I want to change this and in the end SubViewTwo(.xib) should appear when tapping the menu point "Sub View Two" So what i did was changing the second repeat of SubViewOn...
I want to make a macro which will inject some code, like: if (foo) { [Bar fooBar]; } and then, where ever I need that, I put FOOBAR in the code.

Hey guys, I've seen apps on the iPhone that if running on 3.0 will use 3.0 features/APIs such as the in-app email composer, and if running on 2.x not using those features, and exiting the app to launch Mail instead. How is this done? My initial thoughts were to use #ifdef __IPHONE_3_0 but that will only work if I actually build the...

I'm using some semi-transparent PNGs as background-images on various websites. These are usually something like a 1x1 image with a 30-percent opaque white layer.
