iOS回收键盘的几种方法

//1.这个方法可以让整个view取消第一响应者，从而让所有控件的键盘隐藏。

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

//2.创建点击方法,从而实现键盘回收

-(void)TapAction:(UITapGestureRecognizer *)sender
{
    [userNameTextField resignFirstResponder];
    [passWordTextField resignFirstResponder];
}
