Answer 1

所以你想UIActivityIndicator在访问服务器时使用它.

首先在连接调用时创建指示符,并在连接didfinishloading时删除活动指示符

//call this when connection start
UIActivityIndicator *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.frame = CGRectMake(140, 236, 37, 37);
[activityIndicator startAnimating];
[self.view addSubview:activityIndicator];
self.view.userInteractionEnabled = NO;

//remove activity indicator while connection did finish loadin
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    [activityIndicator stopAnimating];
    [activityIndicator removeFromSuperview];
    self.view.userInteractionEnabled = YES;
}
