点击view或者tableview隐藏键盘

一般view

```

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

[textFiled resignFirstResponder];

}

```

tableView里面添加手势

#pragma 添加手势

UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];

[self.tableview addGestureRecognizer:gestureRecognizer];

gestureRecognizer.cancelsTouchesInView = NO;       //很关键,如果没有这个,tableView的cell的点击事件不会响应。
