Is it possible to pin a UIView's top to the bottom of the navigation bar?

Question

I'm trying to position my UIView to be 20pt under the navigation bar, but when I set it relative to the view on the view controller it's still under the navigation bar at 20pt, and I don't want to hardcode it.

Is it possible to position it away from the navigation bar?

Answer 1

To do this programmatically use the topLayoutGuide of your view controller:

override func viewDidLoad() {
    ...
    myView.topAnchor.constraint(equalTo: self.topLayoutGuide.bottomAnchor).isActive=true
    ...
}

Answer 2

Try adding contraint with TopLayoutGuide,

The main difference between TopLayoutGuide and self.view is, top layout guide starts with bottom of status bar + bottom of navigation bar(if exist), but self.view always start from (0,0) coordinate in iOS 7 for translucent navigation bar.

So in your case you should try pinning from top layout guide.
