PhotoLibrary未打开

Question

图片库没有打开。相机工作正常，但从照片库获取的图像却没有显示空白屏幕。昨天很好，但今天不开。请帮助任何帮助将学徒。我是Ios系统的新成员

 @IBAction func uploadImageClick (sender : UIButton){
        let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .ActionSheet)
        let deleteAction = UIAlertAction(title: "Choose From Gallery", style: .Default, handler: {
            (alert: UIAlertAction!) -> Void in
            self.picker.allowsEditing = true
            self.picker.sourceType = .PhotoLibrary
            self.presentViewController(self.picker, animated: true, completion: nil)

        })


        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: {
            (alert: UIAlertAction!) -> Void in

        })
        optionMenu.addAction(deleteAction)

        optionMenu.addAction(cancelAction)
        self.presentViewController(optionMenu, animated: true, completion: nil)
    }
 extension NewsViewController : UIImagePickerControllerDelegate,UINavigationControllerDelegate{

    func imagePickerController(
        picker: UIImagePickerController,
        didFinishPickingMediaWithInfo info: [String : AnyObject]){
        let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage

        dismissViewControllerAnimated(true, completion: nil)
    }
}
