Question

I have a universal app, the code is the same. I have a UIScrollView in which has the scrollToTop working on the iPad but not on iPhone. I am pretty frustrated by this.

I know there’s a similar thread posted here, but that is not the case. I used to have the scrolling to work before this both on the iPad and iPhone. Any idea what to look for?

The structure of the code is like this. I have a mainVC called A. I then have a VC called B. There is also another VC called C, which has a UIScrollView. I added C as B’s child view controller. and then B as A’s child VC. Now the scroll view on C did not have the scrollToTop working.

The delegate scrollViewShouldScrollToTop is also called only in the iPad, not in the iPhone.

Take a look at my answer to the question you’ve talked about. I’ve just added it a moment ago.

EDIT

I don’t have the original code I’ve made, but it should be like that:

-(void)cleanUp:(UIScrollView*)view{
    if([view isKindOfClass:[UIScrollView class]]){
        view.scrollsToTop = NO;
    }else{
        for(UIScrollView* subview in view.subviews){
            if([subview isKindOfClass:[UIView class]]){
                [self cleanUp:subview];
            }
        }
    }
}

and you can call it like this:

[self cleanUp:self.view];

You may also need even more tough variant of that routine (sometimes you may have a tableView inside a scrollView or something like that):

-(void)cleanUp:(UIScrollView*)view{
    if([view isKindOfClass:[UIScrollView class]]){
        view.scrollsToTop = NO;
    }
    for(UIScrollView* subview in view.subviews){
        if([subview isKindOfClass:[UIView class]]){
            [self cleanUp:subview];
        }
    }
}
