我有一个错误说 Redundant Conformance to Protocol UINavigationControllerDelegate
所以这是我的独立代码。
class DelegateProfileViewController: FormViewController, MFMailComposeViewControllerDelegate, UINavigationControllerDelegate {
class ChatViewController: JSQMessagesViewController, UIActionSheetDelegate, UIImagePickerControllerDelegate,
UINavigationControllerDelegate {
class EditSubGroupViewController: FormViewController, SelectUsersFromSubGroupDelegate, SelectSingleFromSubGroupDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
extension CreateEngagementViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
class FeedViewController: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate, DZNEmptyDataSetSource, DZNEmptyDataSetDelegate, UITextFieldDelegate {
你明白了。这些错误中的每一个都会出现 Redundant Conformance of BLANK to protocol UINavigationControllerDelegate。
如果有人能告诉我为什么这些错误会破坏我的项目，我会很高兴。谢谢
最佳答案
如果子类声明符合已从父类(super class)继承的协议(protocol)，您将收到该错误消息
举个例子:如果在你的情况下 FormViewController 已经符合 UINavigationControllerDelegate
class FormViewController: UINavigationControllerDelegate
那么就不需要通过这样做再次符合它:-
class DelegateProfileViewController: FormViewController, MFMailComposeViewControllerDelegate, UINavigationControllerDelegate
应该改为:-
class DelegateProfileViewController: FormViewController, MFMailComposeViewControllerDelegate
这将删除您的冗余一致性。希望您明白我在说什么。
关于swift - 与 NavigationControllerDelegate 的冗余一致性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44856466/
