Preventing iOS to lock screen

[erva 2]

Is there way to prevent iOS automatically lock screen?

 

I'am my self using one fitness app and it stays visible when doing workout, so it should be possible.

In Fmx this would look somewhat like this:

function  DoLocked(const ALock : Boolean) : Boolean;
var
    UIApp : UIApplication;
begin
    UIApp := TUIApplication.Wrap(TUIApplication.OCClass.sharedApplication);

    if ALock  then
    begin
        UIApp.setIdleTimerDisabled(True);    // aquire  wakelock
        Result := True;
    end
    else
    begin
        UIApp.setIdleTimerDisabled(False);  // release wakelock
        Result := False;
    end;
end;

I put some more functionality around that basic one, to make it workable on all platforms, and to avoid double-enabling,
but I removed that from the code above.
