Force Subview to fill parent

Question

I have some subviews that I place inside each of my tab bar's view controllers. Right now I'm sizing it with a pixel count but it only works on the iPhone 4 and 4s and not the iPhone 5 because of the longer screen size. I could check for the device and then size it that way but I feel like there has to be an easier way to do this.

viewController1.view.frame = CGRectMake(0, 0, 320, 460);

I colored the subview yellow so it's easier to see.

1. You should NOT change frame of tabbar's content view controller's view. UITabBar takes itself care of sizing the child view controller's frame properly.
2. If you want to add subview to content view controller (controller under some tab) and make that view to always automatically resize with the controllers main view (self.view), you can use combination of superviews frame and autoresizing.

Example code (you can do this in - (void)viewDidLoad for example):

UIView *view = [[UIView alloc] initWithFrame:self.view.bounds];
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:view];

Answer 2

If you want to do this by setting frame than DO this:

[childView setFrame:childView.superview.bounds];
