UIAlertController is Crashed (iPad)
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)
try this code:
shareMenu.popoverPresentationController.sourceView = self.viewshareMenu.popoverPresentationController.sourceRect = CGRectMake(self.view.bounds.size.width / 2.0, self.view.bounds.size.height / 2.0, 1.0, 1.0)self.presentViewController(shareMenu, animated: true, completion: nil)
Swift 4
popoverPresentationController.permittedArrowDirections = .init(rawValue: 0)popoverPresentationController.sourceView = self.viewpopoverPresentationController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
