autoresize of uiview - objective-c

Question

I have a UIView in a UITabController.
And there is a UITableView in it.
When toggling in call status bar it doesn't do anything and the view is not automatically resized.
It assumes the right size based on whether the in call UIStatusBar was toggled when the app starts but if the UIStatusBar is toggled whilst the app is running nothing changes.
Another tab view with a UINavigationController seems to resize fine.
Here is the code
if ([indexPath indexAtPosition:0] == 0 || [indexPath indexAtPosition:0] == 1) {
if (!airportChooser) {
airportChooser = [[AirportChooserController alloc] init];
airportChooser.targetController = self;
airportChooser.view.autoresizesSubviews = YES;
airportChooser.view.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[airportChooser.view setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth];
}
airportChooser.target = [indexPath indexAtPosition:0];
[self.parentViewController.parentViewController.view addSubview:airportChooser.view];
self.parentViewController.parentViewController.view.autoresizesSubviews = YES;
self.parentViewController.parentViewController.view.contentMode = UIViewContentModeRedraw;
[self.parentViewController.parentViewController.view setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth];
airportChooser.view.contentMode = UIViewContentModeRedraw;
//[airportChooser open];
}

Answer 1

Did you set the resizing mask of the UIView correctly? You can set it in Interface Builder in the size tab, it's the red lines that you can click.
You can also set it in code using something like:
[view setAutoresizingMask:UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleHeight];
Also make sure the superview has set autoresizesSubviews to YES.
You can find more information about this in the UIView documentation.

Whilst klaaspeiter's answer makes sense and in some cases may be the right answer
in my specific case it was because I was adding a sub view to a UINavigationController's view with addSubview instead of pushViewController:view animated:NO;
