Answer 1

Hope this helps.

- (void)viewDidLayoutSubviews {
    [self performSelector:@selector(updateContentSize)
               withObject:nil
               afterDelay:0.25];

}

-(void)updateContentSize{
    UIView *viewLast = [viewContent viewWithTag:100];
    scrollViewAd.contentSize = CGSizeMake([UIScreen mainScreen].bounds.size.width, CGRectGetMaxY(viewLast.frame));
}

With AutoLayout enabled, make sure Vertical Spacing (@"V:|-[subview]-|") is applied between the UIScrollView and its subview. If your scrollView is for horizontal scrolling, apply Horizontal Spacing (@"H:|-[subview]-|").
