Thanks for you answer, my code here: (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.textFeild resignFirstResponder]; } And I hook UIResponder, find resignFirstResponder return YES, but key board is still there, and can't get the UIKeyboardWillHideNotification.

Thanks for your answer. This problem exists in UIKit projects and devices. The keyboard is called up by the WKWebview input box, not the UITextField. Is there any idea to solve this problem? Javascript code like this： input.foucus
