What is the top bar height of iPhone X?

Question

I would like to know exact height of top bar of iPhone X. Could you please mention the status bar and navigation bar height of iPhone X. Please help me.

Answer 1

You can use the navigation bar's .frame property to figure out the overall height of the top bar area:

Swift 5.0:

let xBarHeight = (self.navigationController?.navigationBar.frame.size.height ?? 0.0) + (self.navigationController?.navigationBar.frame.origin.y ?? 0.0)

ObjC:

CGRect navbarFrame = self.navigationController.navigationBar.frame;
float topWidth  = navbarFrame.size.width;
float topHeight = navbarFrame.size.height + navbarFrame.origin.y;

I suppose this is a bit of a cheat, but adding the navbar's height with its y origin seems to give the correct total height regardless of device.

Use it if you want to know where need start content

extension UIViewController {
  var navigationBarbarContentStart: CGFloat {
    return self.navigationBarTopOffset + self.navigationBarHeight
  }
  var navigationBarTopOffset: CGFloat {
    return self.navigationController?.navigationBar.frame.origin.y ?? 0
  }

  var navigationBarHeight: CGFloat {
    return self.navigationController?.navigationBar.frame.height ?? 0
  }
}
