ios - bloqueo al mostrar UIPopOverPresentationController

swift crash

Question

*** Aplicación de finalización debido a excepción no detectada ''NSGenericException'', razón por la cual: ''UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x1a56bd90>) debe tener un conjunto de fuentes no fuente o barButtonItem antes de que ocurra la presentación.''

Answer 1

Modifiqué con el código a continuación y encontré la solución.

if (DeviceType.IS_IPAD == false)
{
presentViewController(activityVC, animated: true, completion: nil)
}else {
// Change Rect to position Popover
let popUp = UIPopoverController(contentViewController: activityVC)
popUp.presentPopoverFromRect(CGRectZero, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}

Answer 2

self.dismissViewControllerAnimated(true, completion: nil)
let textToShare:String = "Lets have a chat!";
let activityVC:UIActivityViewController = UIActivityViewController(activityItems: [textToShare], applicationActivities: nil)
let excludeActivities = [UIActivityTypeAirDrop, UIActivityTypePrint, UIActivityTypeSaveToCameraRoll, UIActivityTypeAssignToContact, UIActivityTypePostToFlickr, UIActivityTypePostToTencentWeibo, UIActivityTypePostToVimeo, UIActivityTypePostToTencentWeibo]
activityVC.excludedActivityTypes = excludeActivities
activityVC.modalPresentationStyle = UIModalPresentationStyle.FormSheet
presentViewController(activityVC, animated: true, completion: nil)
