Ipad UITableView无法在didselectRowAtIndexPath之后向下滚动

我在iPAD上有一个UITableViewController，当我第一次加载tableview时，我可以滚动到底部，但是如果用DidSelectRowatineXpath选择一个单元格，我就不能再滚动到底部了，tableview一直在反弹，这是一个非常奇怪的行为。我放了一些日志来获取所有帧/边界/contentSize/contentInset/contentOffset。 每次点击桌子高度都会不断增加，我不知道如何解决这个问题

 if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
            if ([self.navigationController.parentViewController isKindOfClass:[UISplitViewController class]]) {

            // iPad split view controller support
            UISplitViewController *split = (UISplitViewController *)self.navigationController.parentViewController;

            NSMutableArray *allControllers = [[NSMutableArray alloc] initWithArray:split.viewControllers];
            NSArray *allControllersCopy = [allControllers copy];

            for(int i = 0;i < allControllersCopy.count;i++)
            {
                UIViewController *s = [allControllersCopy objectAtIndex:i];
                if ([s isKindOfClass:[UINavigationController class]]) {
                    NSLog(@"UINavigationController at index : %d",i);
                }
                NSLog(@"custom split : %@", s.title);

            }
            UINavigationController *nav = [split.viewControllers objectAtIndex:1];

            allControllers = [[NSMutableArray alloc] initWithArray:nav.viewControllers];

            for(int i = 0;i < allControllers.count;i++)
            {
                UIViewController *s = [allControllers objectAtIndex:i];
                if(![s isKindOfClass:[MVPTaskViewController class]])
                {
                    [nav popViewControllerAnimated:NO];

                }
            }
            self.nTaskViewController = [nav.viewControllers objectAtIndex:0];
            self.nTaskViewController.selectedTask = selectedTask;
            [self.nTaskViewController updateTask:self.nTaskViewController.selectedTask];

            NSIndexPath *cellAtIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section];
            [self.tableView scrollToRowAtIndexPath:cellAtIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];

            NSLog(@"tableView frame height %f",self.tableView.frame.size.height);
            NSLog(@"tableView frame width %f",self.tableView.frame.size.width);

            NSLog(@"tableView contentSize height %f",self.tableView.contentSize.height);
            NSLog(@"tableView contentSize width %f",self.tableView.contentSize.width);

            NSLog(@"tableView content offset x %f - y %f",self.tableView.contentOffset.x, self.tableView.contentOffset.y);

        }

可能是罪魁祸首。

我找到了一个解决方案。我不知道这是否是解决问题的正确方法，但它确实有效

我在nsindepath*cellAtIndexPath=[nsindepath indexPathForRow:indepath.row-instation:indepath.section]之后添加了didselectrowatinexpath；[self.tableView ScrollToRowatineXpath:CellatineXpath atScrollPosition:UITableView ScrollPosition:是]

希望对其他人有所帮助我已经尝试过了，但没有成功。问题是，在第一次单击单元格后，uitableview高度会发生变化，并且我看不到列表的bootom，如果我尝试滚动，我会被反弹回来
