Get safe area inset top and bottom heights
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 and above
// 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
}
To get the height between the layout guides you just do
let guide = view.safeAreaLayoutGuide
let height = guide.layoutFrame.size.height
So full frame height = 812.0
, safe area height = 734.0
Below is the example where the green view has frame of guide.layoutFrame
