Adding activity indicator to alert view

Question

I want to add an activity indicator to alert view, so that the user waits while file download operation is in progress.

I checked one of the post, it says addSubView doesn't work on UIAlertView in iOS 7 and above, so someone suggested using:

[alertView setValue:indicator forKey:@"accessoryView"]

So, is it the correct way, does it go with HIG of iOS. If not, what is the correct way to do it?

Answer 1

Using UIAlertView for displaying progress of file download itself is not a proper design decision. Ideally you should use alert view only to display alerts or prompts? People use it for user input as well but not really recommended.

I would either use plain UIActivityIndicatorView or UIProgressView to display your actual download progress.

Answer 2

It's not typical to add subviews to UIAlertView I would rather use one of the library to present alert and activity indicator.

MBProgressHUD or SVProgressHUD
