Dismiss UIAlertView after 5 Seconds Swift


I've created a UIAlertView that contains a UIActivityIndicator. Everything works great, but I'd also like the UIAlertView to disappear after 5 seconds.

How can I Dismiss my UIAlertView after 5 seconds?

 var alert: UIAlertView = UIAlertView(title: "Loading", message: "Please wait...", delegate: nil, cancelButtonTitle: "Cancel");

 var loadingIndicator: UIActivityIndicatorView = UIActivityIndicatorView(frame: CGRectMake(50, 10, 37, 37)) as UIActivityIndicatorView
 loadingIndicator.center = self.view.center;
 loadingIndicator.hidesWhenStopped = true
 loadingIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.Gray
 loadingIndicator.startAnimating();

 alert.setValue(loadingIndicator, forKey: "accessoryView")
 loadingIndicator.startAnimating()

 alert.show()

Solution

  • You can dismiss your UIAlertView after a 5 second delay programmatically, like so:

    alert.show()
    
    // Delay the dismissal by 5 seconds
    let delay = 5.0 * Double(NSEC_PER_SEC)
    var time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
    dispatch_after(time, dispatch_get_main_queue(), {
        alert.dismissWithClickedButtonIndex(-1, animated: true)
    })
