UIAlertController is Crashed (iPad)

Question

I am using Xcode 6 to develop an iOS Application.

When I used UIAlertController, it can be worked well on iPhone 6 simulator, but crashes on iPad simula

Answer 1

To keep it device independent, rather use it as shown in the snippet below. This code will return nil for popoverPresentationController on an iPhone / compact size device, so you can safely use it in universal projects.

if let popoverPresentationController = shareMenu.popoverPresentationController {
    popoverPresentationController.sourceView = self.view
    popoverPresentationController.sourceRect = sender.bounds
}
self.presentViewController(shareMenu, animated: true, completion: nil)
