Question

I have a scrollview inside which i have 20 UItextviews. The scrollview is not working. I have set the following in viewdidload.

self.MainScroll.contentSize =          


        

Answer 1

Update the content size after some delay as below.

- (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));
}
