IOS中UIWebView加载Loading的实现方法

                                                                delegate: self
                                                 cancelButtonTitle: nil
                                                 otherButtonTitles: nil]; 
     UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
     activityView.frame = CGRectMake(120.f, 48.0f, 38.0f, 38.0f);
     [myAlert addSubview:activityView];
     [activityView startAnimating];
     [myAlert show];
     }
}
- (void)webViewDidFinishLoad:(UIWebView *)webView{
      [myAlert dismissWithClickedButtonIndex:0 animated:YES];
}

 

方法三：使用UIWebView来加载gif图片，除非你要用到webView,不然就不要使用这种方式来实现

 

复制代码
NSData *gif = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"1" ofType:@"gif"]];  
// view生成  
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(100, 100, 70, 30)];  
webView.userInteractionEnabled = NO;//用户不可交互  
[webView loadData:gif MIMEType:@"image/gif" textEncodingName:nil baseURL:nil];  
[self.view addSubview:webView];
