Question

I’ve got one question about the memory management of the NSMutableArray. I create an object of my custom class and add this object to a NSMutableArray. Is this automatically retained, so that I can release my created object?

Thanks!

Yes, it is automatically retained. You should release your object after adding it to the array (or use autorelease)

For example:

NSMutableArray *array = [[NSMutableArray alloc] init];

[array addObject:[[[MyClass alloc] init] autorelease]];

// or

MyClass * obj = [[MyClass alloc] init];

[array addObject:obj];

[obj release];
