Allocation using temp, why is this way better?

Question

//.h file
@property(nonatomic, retain) NSMutableDictionary *data;

//.m file
NSMutableDictionary *temp = [[NSMutableDictionary alloc] init];
self.data = temp;
[temp          


        

Answer 1

The second way leaks the newly-created dictionary. You could use:

self.data = [NSMutableDictionary dictionary];

And it would be as safe as your first example.
