增加点击事件

    UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hiddenKey)];
    [_myTableView addGestureRecognizer:tap];

触发方法

- (void)hiddenKey {
   [self.view endEditing:YES];
}

防止键盘被覆盖

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

偏移

#pragma mark - keybord(监测键盘响应方法)
- (void)keyboardWillShow:(NSNotification *)notification {
    [UIView animateWithDuration:0.25 animations:^{
        [_myTableView setContentOffset:CGPointMake(0, 300)];
    } completion:nil];
}
- (void)keyboardWillHide:(NSNotification *)notification {
    [UIView animateWithDuration:0.25 animations:^{
        [_myTableView setContentOffset:CGPointMake(0, 0)];
    } completion:nil];
    
    
}
