SafeAreaInsets Not Returning Safe Area on App Start; iPhone SE, 7 & 8

[Calum Anderstrem 1]

Hi,

 

The following code is used in an app to retrieve the safe area on iOS:

 

  function GetSafeAreaLayout: TRectF;
  var
    App: UIApplication;
    Win: UIWindow;
    Guide: UILayoutGuide;
  begin
    App := TUIApplication.Wrap (TUIApplication.OCClass.sharedApplication);
    Win := TUIWindow.Wrap (App.windows.objectAtIndex (0));
    Guide := Win.safeAreaLayoutGuide;
    Result := Guide.layoutFrame.ToRectF;
  end;

 

It is triggered in Resize, and worked for all iPhones when compiled under RAD 11.1. However, compiling under 11.2 and 11.3 patch 1, while the above function completes successfully on iPhone SE, 7 & 8, Result.Top returns as 0 when the app first starts (i.e. causes app to overlay system menu at top of phone). Either calling the function again after app start, or re-orientating the phone fixes the issue. This start-up problem does not happen on the iPhoneX.

 

Has anyone else encountered this issue and know of a fix, or is there a better, more reliable way to access the safe area?

 

Please accept my thanks in advance.

Have you tried to use it in/after FormShow?

Hi Rollo62,

 

Retrieving the Safe Area in FormShow worked. Very grateful, thank you!
