Is calling super in a category the same as calling it in a subclass?

Question

Does calling [super init] do the same thing in a category as a subclass? If not, what\'s the difference?

Answer 1

Given the below example, super will call UIView init (not UINavigationBar init method)

@implementation UINavigationBar (ShadowBar)
- (void)drawRect:(CGRect)rect {
    //draw the shadow ui nav bar
    [super init];
}
@end

If you subclass it, [super init] will call UINavigationBar init method.

So yes, if there are additional things you will do in UINavigationBar init (extra from UIView) they do different things.
