iOS aspect fit and center

Question

I'd like to call

[self.view setContentMode:UIViewContentModeScaleAspectFit | UIViewContentModeCenter];

where self is an instance of UIViewController. This doesn't seem to work; what are the direct alternatives, if any?

why do you say that it does not work? what is the content of the view that you expect to be scaled? — sergio, Aug 13 '11 at 07:17

The contentMode is not a mask; you can't use | to combine values, you'll have to pick one. UIViewContentModeScaleAspectFit should center the content if it doesn't fit the view.

You will need to set contentMode once when the view loads and then center it in viewWillLayoutSubviews which is called upon device rotation.

override func viewDidLoad() {
  super.viewDidLoad()
  //additional code to instantiate and setup image
  imageView.contentMode = .ScaleAspectFit
  self.view.addSubview(profileImageView)
}

override func viewWillLayoutSubviews() {
    imageView.center.x = view.center.x
    //or imageView.center = view.center
    //or imageView.center.y = view.center.y
}
