Extra bottom space/padding on iPhone X?

Question

On the iPhone X in portrait mode, if you set a bottom constraint to safe area to 0, you will end up with an extra space at the bottom of the screen. How do you get programma

Answer 1

use this line to become your bottom value for iPhoneX

if #available(iOS 11.0, *) {
            let bottomPadding = view.safeAreaInsets.bottom
  }

and don't forget to add this in layoutSubviews() because safeAreaInsets has the correct size in layoutSubviews() otherwise you will become wrong values.

Answer 2

In iOS 11, views have a safeAreaInsets property. If you get the bottom property of these insets you can get the height of the bottom padding while on iPhone X:

if #available(iOS 11.0, *) {
    let bottomPadding = view.safeAreaInsets.bottom
    // ...
}

(likewise for the top padding with status bar)

Answer 3

In Objective-C

if (@available(iOS 11.0, *)) {
   UIWindow *window = UIApplication.sharedApplication.keyWindow;
   CGFloat bottomPadding = window.safeAreaInsets.bottom;
}

Answer 4

UIApplication.shared.windows.first?.safeAreaInsets.bottom ?? 0.0

iOS 13 and up

Answer 5

var bottomPadding: CGFloat = 0.0
if #available(iOS 11.0, *) {
     let window = UIApplication.shared.keyWindow
     bottomPadding = window?.safeAreaInsets.bottom ?? 0.0
}

Now you can use bottomPadding as per your needs.

Answer 6

iOS 11 (a mix from answers above)

let padding = UIApplication.shared.keyWindow?.safeAreaInsets.bottom ?? 0
