Answer 1

它非常简单.只需创建一个UIActivityIndi​​catorView并将其作为子视图添加到UIAlertView.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@" " message:@" " delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
    UIActivityIndicatorView *progress= [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(125, 50, 30, 30)];
    progress.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
    [alert addSubview:progress];
    [progress startAnimating];

    [alert show];
