尝试一下：

    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)

我假设您点击一个按钮以启动UIImagePickerController。我怀疑如果您是使用界面生成器设计的，则可能会将您的按钮连接到多个IBAction方法上。

转到情节提要，然后右键单击按钮。如果按钮连接到多个“已发送事件”，那就是您的问题。删除不相关的内容（也许您在代码中删除的旧内容仍处于连接状态）。
