Get safe area inset top and bottom heights

Question

On the new iPhone X, what would be the most proper way to get both top and bottom height for the unsafe areas?

Answer 1

Try this :

In Objective C

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

In Swift - iOS 13.0 and above

// Use the first element from windows array as KeyWindow deprecated

if #available(iOS 11.0, *) {
    let window = UIApplication.shared.windows[0]
    let topPadding = window.safeAreaInsets.top
    let bottomPadding = window.safeAreaInsets.bottom
}

In Swift

if #available(iOS 11.0, *) {
    let window = UIApplication.shared.keyWindow
    let topPadding = window?.safeAreaInsets.top
    let bottomPadding = window?.safeAreaInsets.bottom
}
