Question

is it allowed to override the setContentOffset method of an UIScrollView while subclassing?? Is this AppStore save?

sample:

-(void)setContentOffset:(CGPoint)contentOffset {
    [super setContentOffset:contentOffset];
    NSLog(@"co: %@",NSStringFromCGPoint(contentOffset));

    if(_willScroll)
        [_svDelegate setContentOffset:CGPointMake(contentOffset.x, contentOffset.y *2)];
}

thanks,

Yes. Lots of iPhone programmers subclass UIScrollView and then replace or extend functionality of public API’s like setContentOffset.

The only correction I would make for you is to use the correct API. It’s not:

setContentOffset:

but instead it’s

setContentOffset: animated:

(i.e. with an animated parameter — Apple’s documentation is linked for you there).
