When a UIActivityViewController is called on the iPhone in this app, it works perfectly, but when called on a iPad, the app crashes. Below is the code I used:
There are two option, the action came from a UIBarButtonitem or UIButton that is a UIView.
func shareButtonPress() {
...
if let actv = activityViewController.popoverPresentationController {
actv.barButtonItem = someBarButton // if it is a UIBarButtonItem
// Or if it is a view you can get the view rect
actv.sourceView = someView
// actv.sourceRect = someView.frame // you can also specify the CGRect
}
self.presentViewController(activityViewController, animated: true, completion: nil)
}
You may have to add a sender to your function like func shareButtonPress(sender: UIBarButtonItem) or func shareButtonPress(sender: UIButton)
