Red recording bar distorting view - ios

Question

I'm having a heck of a time figuring this out.
I have a modal view that appears when tapping on one of the tabs of a tab bar. In the new view that takes over the whole screen, there is a button a user taps to start recording audio, and when they're finished recording audio, or if they cancel recording, the modal view is dismissed.
The problem is that, once they start recording, that red recording bar should appear on this new view. But it's not. And as soon as that view is dismissed, in the next view that is presented (a table view, which is found in one of the tabs), you can see the red recording bar at the top for a split second and it disappears BUT it shoves the tab bar down the screen and obscures part of the tab bar, which you can see in the third screenshot below.
Modal view pops up - recording is currently in progress, but red recording indicator is not showing at the top
Right when the recording is done and the view is about to disappear, the red bar appears
And once the view disappears and we're left with the table view that lives in one of the tabs, the tab bar is shoved down past the bottom of the screen :( It SHOULD look like this (with the fourth tab selected):
My questions:
1) What am I doing wrong that's causing the red recording bar to NOT show up in the modal view?
2) Is there a way to maybe refresh this view from the screenshot so that when it appears, it resizes properly?
Here's the code. I removed some of the non-important stuff that doesn't deal with the views.

Sorry for the wall of text and the length. I'm really stumped.

Answer 1

Solution : You have to reset frame for UITabBarController.
1. Initially frame for UITabBarController will be (0,0,screenWidth,screenHeight).
2. But when this recording red bar appear it becomes (0,20,screenWidth,screenHeight)
3. Here you are supposed to change height for UITabBarController
CGRect changedFrame = objMainTabBarController.view.frame;
changedFrame.size.height = [UIScreen mainScreen].bounds.size.height - CGRectGetMinY(changedFrame);
objMainTabBarController.view.frame = changedFrame;
That's it..
