Get safe area inset top and bottom heights


What would be the most proper way to get both top and bottom height for the unsafe areas?

Solution

  • 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

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

    In Swift - iOS 13.0+

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

    if #available(iOS 13.0, *) {
        let window = UIApplication.shared.windows.first
        let topPadding = window.safeAreaInsets.top
        let bottomPadding = window.safeAreaInsets.bottom
    }
    

    In Swift - iOS 15.0+

    // Use the keyWindow of the currentScene

    if #available(iOS 15.0, *) {
        let window = UIApplication.shared.currentScene?.keyWindow
        let topPadding = window.safeAreaInsets.top
        let bottomPadding = window.safeAreaInsets.bottom
    }
