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. 通过navigationType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");
}
//点击返回按钮
case UIWebViewNavigationTypeBackForward
{
NSLog(@"back");
}
//点击重新加载按钮
case UIWebViewNavigationTypeReload
{
NSLog(@"reload");
}
//表单重新提交
case UIWebViewNavigationTypeFormResubmitted
{
NSLog(@"formResubmitted");
}
default:
break;
}
return YES;
}

@interface BaseViewController ()

UIScrollView *scollview=(UIScrollView *)[[webview subviews]objectAtIndex:0];
scollview.bounces=NO;
// Do any additional setup after loading the view.

[super didReceiveMemoryWarning];

-(void)viewDidUnload{
[super viewDidUnload];
self.requestUrl=nil;
