1. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

   {

       [super touchesBegan:touches withEvent:event];

       [self.view endEditing:YES];

       //隐藏键盘

       [_descrViewa resignFirstResponder];

       

       

       //    [self.editingTextField  resignFirstResponder] ;

       

   }

2. 第二种方式

3.  

       UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@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.view addGestureRecognizer:tapGestureRecognizer];

4. //隐藏键盘

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

       [_nameField resignFirstResponder];

   }
