Have a look at the following code -(void) test { testString = NULL; dispatch_async(dispatch_get_global_queue(0, 0), ^{ dispatch_async(dispatch_get_main_queue(), ^{ NSString* aString = [[NSMutableString alloc] init]; NSLog(@"retainCount: %d",[aString retainCount]); testString = [aString retain]; [aString release]; dispatch_async(dispatch_get_main_queue(), ^{ NSLog(@"retainCount: %d",[testString retainCount]); }); }); }); }
As expected the output is: retainCount: 1 retainCount: 1 However when I change [aString release] to [aString autorelease] the output shows: retainCount: 1 retainCount: 2 Why? BTW I first noticed this behavior when my application started leaking the QTMovie objects I was creating in a block. - Henk_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
