Answer 1

嘗試這個：

    let imagePicker = UIImagePickerController()
    imagePicker.delegate = self

    let cameraAction = UIAlertController(title: "Title", message: "Choose to upload a picture", preferredStyle: .alert)
    cameraAction.addAction(UIAlertAction(title: "Camera", style: .default, handler: {(action) in

        imagePicker.sourceType = UIImagePickerController.SourceType.camera
        self.present(imagePicker, animated: true){

        }
    }))
    cameraAction.addAction(UIAlertAction(title: "Photo Library", style: .default, handler: {(action) in

        imagePicker.sourceType = .photoLibrary
        self.present(imagePicker, animated: true){

        }
    }))
    imagePicker.allowsEditing = true
    self.present(cameraAction, animated: true)

我假設您點擊一個按鈕來啟動UIImagePickerController 。 我懷疑如果您使用界面構建器設計了按鈕，則可能會將按鈕連接到多個IBAction方法。

轉到情節提要，然后右鍵單擊按鈕。 如果按鈕連接到多個“已發送事件”，那就是您的問題。 刪除不相關的內容（也許您在代碼中刪除的舊內容仍處於連接狀態）。
