ios - Swift中的相机和库 Action

我在Swift编码方面很新，而且我对相机和库的使用有问题。我有这部分代码：

    @IBAction func camera(_ sender: Any) {

    if !UIImagePickerController.isSourceTypeAvailable(.camera) {
        return
    }

    let cameraPicker = UIImagePickerController()
    cameraPicker.delegate = self
    cameraPicker.sourceType = .camera
    cameraPicker.allowsEditing = false

    present(cameraPicker, animated: true)
}

@IBAction func openLibrary(_ sender: Any) {
    let picker = UIImagePickerController()
    picker.allowsEditing = false
    picker.delegate = self
    picker.sourceType = .photoLibrary
    present(picker, animated: true)
}

}
在cameraPicker.delegate=self和picker.delegate=self中，会抛出如下错误：
无法将“ViewController”类型的值赋给类型（UIImagePickerControllerDelegate和UINavigationControllerDelegate）
我真的不知道怎么解决这个问题。如果有人能帮我做这个我会很感激的，提前谢谢你！

最佳答案

你只需要像

class ViewConroller: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
   ...
}
