Question

Instruments is showing that i get a memory leak right there:

-(id) copyWithZone: (NSZone *) zone
{ 
    Layer *copy = [[Layer allocWithZone:zone]init];
    NSData *imageData = [[NSData alloc]initWithData:_image];
    copy.image = imageData;
    [imageData release];

    return copy;
}

The image property is declared as it follows:

@property (nonatomic, retain) NSData *image;

Here is a screenshot of instruments, to prove that i am not lying.

Anyone see a problem in there?

Here is how we solved it, following the instructions given here.

-(id) copyWithZone: (NSZone *) zone
{
    Layer *copy = [[Layer allocWithZone:zone]init];
    copy->_image=nil;
    [copy setImage:[self image]];
    return copy;
}
