UIVideoEditorController委托方法被调用两次

Question

我正在使用UIVideoEditorController，但是成功委托方法为我调用了两次。但是，所有传递的对象的所有指针都告诉它发送完全相同的数据。

let editor = UIVideoEditorController()
editor.videoMaximumDuration = 10.0
editor.videoQuality = .typeIFrame1280x720
editor.delegate = self
editor.videoPath = // some path goes here
self.present(editor, animated: true, completion: nil)

然后，以下方法将“ here”打印两次。

func videoEditorController(_ editor: UIVideoEditorController, didSaveEditedVideoToPath editedVideoPath: String) {
    print("here")
    self.dismiss(animated: true, completion: nil)
}

Answer 1

func videoEditorController(_ editor: UIVideoEditorController, didSaveEditedVideoToPath editedVideoPath: String) {
    editor.delegate = nil
    editor.dismiss(animated: true)
}

Answer 2

是的，我知道，这是不好的方式，但工作:)

var isSaved:Bool = false

func videoEditorController(_ editor: UIVideoEditorController, didSaveEditedVideoToPath editedVideoPath: String) {
   if(!isSaved) {
      print("here")
      self.isSaved = true
   }
       self.dismiss(animated: true, completion: nil)
   }
