1.隐藏上下滚动时出边界的后面的黑色的阴影

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

 

2. 禁用拖拽时的反弹效果

[(UIScrollView *)[[webView subviews] objectAtIndex:0] setBounces:NO];

 

3. 判断用户点击类型

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{    switch (navigationType)     {        //点击连接        case UIWebViewNavigationTypeLinkClicked:        {            NSLog(@"clicked");        }            break;        //提交表单        case UIWebViewNavigationTypeFormSubmitted:        {            NSLog(@"submitted");        }        default:            break;    }    return YES;}
