UIWebView相关设置

让UIWebView的背景透明:

1
2
self.webView.backgroundColor = [UIColor clearColor];
self.webView.opaque = NO

这样就可以背景透明了,如果还是无效的话,那么需要在html里面加入:

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

去掉uiwebview滚动到边缘时的阴影效果:(不要重复对一个uiwebview调用这个方法,会导致滚动条消失)

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

去除copy/paste的响应:

1
[webView stringByEvaluatingJavaScriptFromString:@"var css = document.createElement(\"style\");css.type = \"text/css\";css.innerHTML = \"* {-webkit-touch-callout: none;-webkit-user-select: none;}\";document.body.appendChild(css);"];
