iPhone 5 simulator - screen size issue??

I have iPhone 4 (real one) to test my application. So far everything is fine. But I tried it with iPhone 5/5S simulator (iOS7.1), my app has some vertical margins and this code:

CGRect screenRect = [[UIScreen mainScreen] bounds];
NSLog(@"%f , %f", screenRect.size.width, screenRect.size.height);

still shows 320x480 resolution. Does it mean, that with real iPhone 5/5S I will get the same gap between the top and bottom edges and my app??

How can I set dynamically my UIViewControllers' width and height to fit the screen? (I am using storyboard just to set the UIView classes to them)

Are you setting the frame explicitly to specific points? If you want your view controller's view to take of the full screen you either need to use autoresize masks or AutoLayout.

Using resize masks:

self.view.frame = 
CGRectMake(0,  0,  CGRectGetWidth(parentView.bounds),  CGRectGetHeight(parentView.bounds);
self.view.autoresizeMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[parentView addSubview:self.view];

This will make the view controller's view always resize to match the parents size. If you're using a Storyboard then the masks can be set in the inspector.


The same can be done with AutoLayout.
