UITableView can't scroll bottom after didselectRowAtIndexPath - ipad

Question

I have a UITableViewController in iPAD, when I first load the tableview, I can scroll to the bottom, but if select one cell with didSelectRowAtIndexPath, I can't scroll anymore to the bottom, the tableView keep bouncing back, it is a really weird behaviour.I've put some logs to get all the frame/bounds/contentSize/contentInset/contentOffset.
At every click the table height keeps growing, I can't understand how to fix this problem.
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);
}
This are the logs I get :

Answer 1

[self.tableView scrollToRowAtIndexPath:cellAtIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
might be the culprit.

Answer 2

I have found a solution.I don't know if it is the right way to fix the problem, but it works.
I have added in didSelectRowAtIndexPath after NSIndexPath *cellAtIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section];[self.tableView scrollToRowAtIndexPath:cellAtIndexPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES];
CGRect tbFrame = [self.tableView frame];
if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation))
{
tbFrame.size.height = 910; }
else {
tbFrame.size.height = 655;
}
[self.tableView setFrame:tbFrame];
Hope to help someonelse
