iPhone memory management: a release after setting self.someProperty = nil
- by ddawber
I am reading the LazyTableImages code that Apple have released and they do something to this effect (in an NSOperation subclass):
- (void)dealloc {
[myProperty release];
[myProperty2 release];
}
- (void)main {
//
// Parse operation undertaken here
//
self.myProperty = nil;
self.myProperty2 = nil;
}
My thinking is that they do this in case dealloc is called before setting properties to nil.
Is my thinking correct here? Are the releases unnecessary, as self.myProperty = nil effectively releases myProperty?
One thing I have noticed in this code is that they don't release all retained objects in dealloc, only some of them, which is really the cause for my confusion.
Cheers
