UITableView not scrolling enough after expanding subview

I have a UITableViewController with a UIView at the bottom. (using storyboard). My UIView is set to hidden and changes state afterwards on click of button. First, I was trying to resize (increase height basically) my UIView on IBAction(buttonClick) using self.concluidoView.frame = CGRectMake(0, 0, 320, 50); but UIView was disappearing instead.

Now, it is correctly expanding UIView with the following code inside IBAction:

[UIView animateWithDuration:1.0
                     animations:^{
                         CGRect frame = self.concluidoView.frame;
                         frame.size.height += 100.0;
                         self.concluidoView.frame = frame;

                     }
                     completion:^(BOOL finished){
                         // complete

                     }];

The problem is that my UITableViewController is not scrolling enough to the new size, since the UIView is the last item in my tableView.

I've tried a few things to solve this problem, including manually trying to resize tableview to increase it's height to the same value of the UIViewincrease. I used the following code:

CGRect tableFrame = self.tableview.frame;
        tableFrame.size.height += 100;
        self.tableView.frame = tableFrame;
        [self.tableview layoutIfNeeded];

The scrolling capacity of my tableviewwas actually smaller after this code. I would like to resize tableviewand allow scrolling, either manually, since I know how much my subviewwill increase, or automatically.

If you change the UITableView's frame, all you'll do is make it extend off screen most likely. What you want to do is get the table view to recognize that the UIView is larger. I'm assuming this UIView is the tableFooterView of your UITableView. Try doing the following:

UIView *footerView = self.tableView.tableFooterView;
self.tableView.tableFooterView = nil;
self.tableView.tableFooterView = footerView;

That will force the UITableView to reexamine the size of the footer view. I've had to do this before when changing the size of a footer view before.
