How to make a transparent UIWebView

7 Solutions Collect From Internet About “How to make a transparent UIWebView”

I recommend:

webView.opaque = NO;
webView.backgroundColor = [UIColor clearColor];

(setting these properties in Interface Builder will work for iOS 5.0+, but for iOS 4.3 you must set the backgroundColor in code)

And include this into your HTML code:

<body style="background-color: transparent;">

Use the recursive method below to remove gradient from UIWebView:

[webView setBackgroundColor:[UIColor clearColor]];
[self hideGradientBackground:webView];

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

    [self hideGradientBackground:subview];

Swift update:

webView.opaque = true
webView.backgroundColor = UIColor.clearColor()

And again, don’t forget to set

<body style="background-color: transparent">

Or better still, instead of an inline style, in your style sheet:

body {
     background-color: transparent

In XCode 6.x uncheck Opaque and change Background’s opacity to 0%. I think other XCode versions will also work.enter image description here

I was able to make my UIWebView transparent by going to ‘Attributes Inspector’ and unchecking Drawing Opaque.

My HTML code just for reference.

    UIWebView* webView =(UIWebView *) [cell viewWithTag:100];
    NSString* htmlContentString = [NSString stringWithFormat:
                                   "<style type='text/css'>html,body {margin: 0;padding: 0;width: 100%%;height: 100%%;}</style>"
                                   "<table style='border:1px solid gray; border-radius: 5px; overflow: hidden;color:white;font-size:10pt' cellspacing=\"0\" cellpadding=\"1\" align='right'><tr>"
    [webView loadHTMLString:htmlContentString baseURL:nil];

For Swift 3 and Xcode 8

self.webView.isOpaque = false;
self.webView.backgroundColor = UIColor.clear

To remove the scrolls and make the UIWebView transparent, try this code below:

webView.opaque = NO;  
webView.backgroundColor = [UIColor clearColor];  

for(UIView *view in webView.subviews){   
     if ([view isKindOfClass:[UIImageView class]]) {  
          // to transparent   
          [view removeFromSuperview];  
     if ([view isKindOfClass:[UIScrollView class]]) {  
          UIScrollView *sView = (UIScrollView *)view;  
          //to hide Scroller bar 
          sView.showsVerticalScrollIndicator = NO;  
          sView.showsHorizontalScrollIndicator = NO;
          for (UIView* shadowView in [sView subviews]){  
               //to remove shadow  
               if ([shadowView isKindOfClass:[UIImageView class]]) {  
                    [shadowView setHidden:TRUE];
