Question

If I have a variable in my view controler

viewcontroller.m

@interface MemoryTestViewController : UIViewController
{
    NSMutableArray *array;
}

@end

in my implementation

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSMutableArray *aux = [[NSMutableArray alloc] initWithCapacity:1];
    array = aux;
    [aux release];
    // Do i have to do array release?
}

Do i have to release my variable array somewhere? Theoricaly i havent allocated that variable…
I testes the memory leaks and even if i dont release anything the instruments doesn’t detect any leak.

No, you don’t need to release. All you do is assign the pointer of aux to your array variable.
array is invalid at the moment where you release aux.
This is probably not as intended. If you want to work with array, you’ll have to retain it.
