去掉UIWebView底部的阴影

#iOS #UIWebView

上下滑动UIWebView的时候, 会发现底部带有黑色的阴影.

下面是去掉阴影的代码片段:

- (void)viewDidLoad
{
  [super viewDidLoad];

  [webView setBackgroundColor:[UIColor clearColor]];
  [webView loadHTMLString:@"This is a completely transparent UIWebView." baseURL:nil];
  [self hideGradientBackground:webView];
}

- (void) hideGradientBackground:(UIView*)theView
{
  for (UIView * subview in theView.subviews)
  {
    if ([subview isKindOfClass:[UIImageView class]])
      subview.hidden = YES;
 	  
	[self hideGradientBackground:subview];
  }
}
