If I create a view, and add it as a subview and also add it to an array, do I have to release it twice? UIView* cat = [[UIView alloc] initWithFrame:someFrame]; [self.view addSubview:cat]; [self.animals addObject:cat]; [cat release]; [cat release]; It just seems weird to me to have 2 release statements, and I haven'...

Hello, I'm having a weird issue, I know it's a bit futile if I don't paste the code here, but I think it would be overkill.

Instruments is pointing out that this is a memory leak, however I'm unsure how to release it properly, or when it should be released. Is there a better convention for assigning properties with new objects that are only needed inside a loop? The specific line is the "expense.addedDate = [NSDate new];". - (void) addObjects:(NSString *)it...

SO I already know about memory management in objective C, and I never had to know about it while programming in .net (C#). But i still have some questions about how everything is done. -Why does the code leak in objective c if we allocate an object and not release it? -Why doesn't this leak in C#? -What are some advantages and disadva...

For the app I'm currently working on, one of my main ViewControllers contains two UITableViews whose contents vary based on what's stored in my model (Core Data backed by SQL). Both tableviews set their delegate and datasource properties to the shared VC they're both subviews of, and I provide the necessary methods in the VC to respond ...

I will post code with my question but to keep it readable i'll get rid of some of the crap, let me know if you want more code posted!
