键盘的隐藏事件

viewDidLoad方法里加载隐藏方法：

{

UserName(UITextField类型)

}

［self hiddenKeyBoard］；

-(void)hiddenKeyBoard

{

    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizeralloc] initWithTarget:selfaction:@selector(keyboardHide:)];

    //设置成NO表示当前控件响应后会传播到其他控件上，默认为YES。

    tapGestureRecognizer.cancelsTouchesInView =NO;

    //将触摸事件添加到当前view

    [self.viewaddGestureRecognizer:tapGestureRecognizer];

}

-(void)keyboardHide:(UITapGestureRecognizer*)tap{

    //UserName的键盘隐藏事件

    [UserNameresignFirstResponder];

    

}
