I am trying to convert this to Arc:

- (BOOL)doSomethingWithSelector: (SEL)aSelector 
{
        [...]
        NSNumber *status = [ self performSelector: aSelector  withObject: a  
withObject: b ];
        [...]
}


Xcode 5.0 complains: "PerformSelector may cause a leak because its selector is 
unknown"

Is there a way to tell the compiler that "aSelector" returns an object which 
does NOT need to get released by the caller ? 
I saw something like "__autoreleasing", but don't know how to apply this in my 
case.

Gerriet.
