Sometimes i saw this type of codeing in objective-c. Why set _imageView to nil after releasing.
- (void)dealloc {
[_imageView release];
_imageView = nil;
[super dealloc];
}
It’s to ensure that you don’t try to reuse the object that you’ve just released.
By setting it to
nil, you ensure that any future messages to it will be tossed away (the behaviour for the standardnilobject) rather than causing a problem.
