performSelector may cause a leak because its selector is unknown

Question

I\'m getting the following warning by the ARC compiler:

\"performSelector may cause a leak because its selector is unknown\".

Answer 1

Because you are using ARC you must be using iOS 4.0 or later. This means you could use blocks. If instead of remembering the selector to perform you instead took a block, ARC would be able to better track what is actually going on and you wouldn't have to run the risk of accidentally introducing a memory leak.
