uiwebview shadow

duplicate with this answer, but not working for me the code accepted as aswer there:

for (UIView* subView in [webView subviews])
{
    if ([subView isKindOfClass:[UIScrollView class]]) {
        for (UIView* shadowView in [subView subviews])
        {
            if ([shadowView isKindOfClass:[UIImageView class]]) {
                [shadowView setHidden:YES];
            }

  • that shadow is from pdf. you cant get rid of it. see my comment below. otherwise both code snippte are to get rid of uiwebview shadows. you will still have pdf shadow inside the view. – Hashmat Khalil Mar 12 '12 at 16:14

There a several threads around here with this topic …

Try this: 

for(UIView *wview in [[[webView subviews] objectAtIndex:0] subviews]) { 
  if([wview isKindOfClass:[UIImageView class]]) { wview.hidden = YES; } 
}

It should work and pass App Store submission, because it's not using any private APIs.

  • yeah i have tried it's working to get rid of shadows from uiwebviews. but i was confused when tried to display pdf. so that shadow in the screen shot is pdf shadow. i found it later. so i ended up not using uiwebview, but quartz. and that was another long story. thanks anyway! – Hashmat Khalil Mar 12 '12 at 16:12
