I'll try to describe it again. I have NIB, NSObject-based owner of
this nib and NSView + NSArrayController in that NIB.
Let's name owner of this NIB MyViewController. It has -init and -dealloc methods
-(id) init
{
self = [super init];
[NSBundle loadNibNamed:@"MyView1" owner:self];
return self;
}
- (void) dealloc
{
// next two lines added after your comment
[pView release];
[pArrayController release];
[super dealloc];
}
In the main window controller I do the following:
- (void) windowDidLoad
{
pViewController = [[MyViewController alloc] init];
pCustomView = [pViewController view]; // I will use this view on
the main window
}
- (void) dealloc
{
[pViewController release]; // this should call -dealloc method of
MyViewController, but it doesn't
// if I call [pViewController retainCount] here, it returns "1"
[super dealloc];
}
Hope, you got the idea of the code.
Array controller is bound to file's owner in NIB, so it holds
reference to it and -release doesn't call -dealloc that should release
array controller that holds a reference... etc....
If I remove binding in NIB file, MyViewController's -dealloc is called
after -release. I added method to MyViewController that breaks binding
and call this method before releasing MyViewController. This helps,
but I think there is a better way to do this.
