问题：在UITableViewController里使用IQKeyboardManager点击textfield键盘不上移。

法1.

- (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];
    [[IQKeyboardManager sharedManager] setEnable:YES];

去掉

//    if (@available(iOS 11.0, *)) {
//
//        self.tableView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
//
//        self.topOffset.constant = Base_NavbarHeight-30;
//
//    }else {
//        self.automaticallyAdjustsScrollViewInsets = NO;
//    }

法2.

- (void)addNotice {
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

#pragma mark 键盘出现
-(void)keyboardWillShow:(NSNotification *)note
{
    CGRect keyBoardRect=[note.userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
    self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyBoardRect.size.height, 0);
}
#pragma mark 键盘消失
-(void)keyboardWillHide:(NSNotification *)note
{
    self.tableView.contentInset = UIEdgeInsetsZero;
}

法3.

- (void)addNotice {
 [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWasShown:)
                                             name:UIKeyboardDidShowNotification object:nil];
    
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(keyboardWillBeHidden:)
                                             name:UIKeyboardWillHideNotification object:nil];}

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    
    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
    self.tableView.contentInset = contentInsets;
    self.tableView.scrollIndicatorInsets = contentInsets;
    
    CGRect aRect = self.view.frame;
    aRect.size.height -= kbSize.height;
    if (!CGRectContainsPoint(aRect, self.InvestInfocell.activityNumber.frame.origin) ) {
        [self.tableView scrollRectToVisible:self.InvestInfocell.activityNumber.frame animated:YES];
    }
}

- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    self.tableView.contentInset = contentInsets;
    self.tableView.scrollIndicatorInsets = contentInsets;
}
