iOS开发中WebView的基本使用方法简介

    
    activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 32.0f, 32.0f)];  
    [activityIndicator setCenter:view.center];  
    [activityIndicator setActivityIndicatorViewStyle:UIActivityIndicatorViewStyleWhite];  
    [view addSubview:activityIndicator]; 

 

    [activityIndicator startAnimating];
   </strong>

加载完成或失败时，去掉loading效果
复制代码
<strong>- (void) webViewDidFinishLoad:(UIWebView *)webView
{
    [activityIndicator stopAnimating];
    UIView *view = (UIView*)[self.view viewWithTag:108];
    [view removeFromSuperview];
    NSLog(@"webViewDidFinishLoad");

 

}
- (void) webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
    [activityIndicator stopAnimating];
    UIView *view = (UIView*)[self.view viewWithTag:108];
    [view removeFromSuperview];
    </strong>
