问题 My application icon's work fine when displaying on iPad and iPhone, however after I build for archive, and create the archive, there is no icon shown. Any ideas?

问题 I am working with several NSManagedObject types with several relationships. How can I tell Core Data to automatically populate object IDs for me? I'm looking for something like an index key in SQL, so that no two instances of a given object are allowed to have the same ID.

问题 I'm trying to Launch an application within my App. For example: If I press a Button in my testApp1, it should Open up testApp2. Is there any Way to do this with the App Identifier?? I heard something about a undocumented method called launchApplicationWithIdentifier: suspend: but that doesn't work for me, or i'm using it wrong.

问题 Before I spend time and money downloading Xcode 4, can anyone tell me whether it comes with a version of gcc (or any other compiler, e.g. LLVM) which supports the AVX instruction set on Sandy Bridge CPUs (i.e. gcc -mavx on mainstream gcc builds) ?
