活动指标

Question

我想在我的应用中使用活动指示器.

我在我的应用程序中使用JSON解析.首先,当我显示数据下载活动指示器时单击同步按钮,下载完成时停止.

同样isuue在这里,当应用程序启动数据下载时,我也在应用程序中放置活动指示器.

我正在使用以下方法进行连接...

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{

}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{

}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{

}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{

}

Answer 1

 UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
 [indicator setCenter:CGPointMake(YourXPoint, YourYPoint)];
 [self.view addSubview:indicator];
 [indicator startAnimating];   

当你想要停止指标使用这个

  [indicator stopAnimating];
