Problems setting dimensions of UIImageView

The code below does as follows:

  • detects width and height of screen
  • sets the dimensions of the screen to a UIImageView
  • sets position of the UIImageView to 0,0

Code (being run in viewDidLoad):

NSUInteger widthOfScreen = [UIScreen mainScreen].bounds.size.width;
NSUInteger heightOfScreen = [UIScreen mainScreen].bounds.size.height;
self.background.frame = CGRectMake(0, 0, widthOfScreen, heightOfScreen);

This is being tested in the Simulator on a iPhone 6.

When the code is run, the debugger says the dimension of the screen and UIImageView are 337x568 which is correct (When I implement the correct NSLog statements). But, the simulator shows a UIImageView that does not fit the screen properly. (It is too big). How can I get this to work?

I think it would be important to note that the original dimensions of the image being showed by the UIImageView are 768x1408.

    According to that website, it seems as if you can't resize a UIImageView in viewDidLoad. It worked when I programmatically created the UIImageView
