UIActivityIndicatorView not displaying in UIAlertView - iOS7 [duplicate]

问题

I need to UIActivityIndicatorView in UIAlertView when loading. But UIActivityIndicatorView is not displaying when I add this with UIActivityIndicatorView not displaying in UIAlertView - iOS7 in iOS 7. And this is working good in iOS 6 & lowest versions. Below is my code.

Is there any solution ? . thanks.

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:nil message:@"\n\n\n\nloading.." delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
[alertView show];

UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
activityIndicator.frame= CGRectMake(50, 10, 37, 37);
activityIndicator.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleLeftMargin;

[alertView addSubview:activityIndicator];

[activityIndicator startAnimating];

回答1:

Apple deprecated addSubview method in case of UIAlertView. So you can't add any subviews any more to AlertView, for example : activity indicator or some progress bar.

Here you can look at my question where people share custom Alerts which will support adding controls

UIAlertView addSubview in iOS7

You can not do customization with UIAlertView

Read this documentation

Best way is create custom UIView which look/feature like UIAlertView and add your activity indicator on this view.
