Question

I have a setter like this:

- (UIImagePickerController *) foto {

    if (_foto == nil) { 
        _foto = [[UIImagePickerController alloc] init];
        _foto.delegate = self;
    }
    return _foto;
}

it is declared like

@property (nonatomic, retain) UIImagePickerController *foto;

with

@synthesize foto = _foto;

on my dealloc I have

[_foto release];

At some point in my code I want to do this

self.foto = nil;

but something in my soul says the object assigned to self.foto previously will leak, because it was alloc on the setter… how do I make it right?

thanks.

Edit: No, that should be fine. As long as you don’t assign something else to _foto before you release, it should work.

Yup. You create an object, then loose the pointer to it. If you throw an autorelease on the init line, that will fix it. You could also use ARC.

The init line doesn’t actually do anything… You assign the pointer to an object you create, then assign it to something else.
