UITextField隐藏键盘的两种方法

1.绑定UITextField的DidEndOnExit事件:点击完成隐藏键盘

- (IBAction)backgroundRegisterKeybroad:(id)sender

{ 

    [textField resignFirstResponder];

}

2.将UITextField所在的View的Class改为UIControl,绑定control的touch down事件:点击背景隐藏键盘

- (IBAction)backdown:(id)sender

{

    [self.view endEditing:YES];

}
