Swift crash wen tapping “Open in Instagram” while using UIDocumentInteractionController
I think your are right.I have the same problem.
before begin the share function, you must create a global variable from UIDocumentInteractionController:
var interactionController: UIDocumentInteractionController?@IBAction func instagramShareButton(sender: AnyObject) { ... interactionController = UIDocumentInteractionController(URL: fileURL) interactionController!.UTI = "com.instagram.exclusivegram" let msgBody = "My message" interactionController!.annotation = NSDictionary(object: msgBody, forKey: "InstagramCaption") interactionController!.presentOpenInMenuFromRect(rect, inView: self.view, animated: true)}This works for me!
