Question

1. What is the correct place to call the clean up code like the following if ARC is enabled?

   if ([EAGLContext currentContext] == mContext)    
       [EAGLContext setCurrentContext:nil];
   

2. In ARC, since memory is managed by the LLVM, can we still override the dealloc method
      without any caveats?

Answer 1

1. You can still call this code in the dealloc, but depending on the structure of your code, there may be a better point for it. Perhaps viewDidUnload

2. You can still override dealloc with the following caveats:

   • You can’t call [super dealloc];
   • You can’t call release, you should only do nil assignments, remove listeners and such in here.
