EUnsupportedPlatformService with message 'Unsupported platform service: Terminate'

[at3s 4]

Delphi 11.2 patch 2.

iOS application raises "EUnsupportedPlatformService with message 'Unsupported platform service: Terminate'" error upon

Application.Terminate;

or

MainForm.Close;

There is no problem with Android application.

Actually it's [Exit] button functionality in the application.

Can someone help?

iOS does not support terminating application, so Delphi does not have that support either.  If Delphi previously implemented Terminate on iOS it was most likely removed as such functionality would cause rejection on the AppStore. See https://stackoverflow.com/questions/355168/proper-way-to-exit-iphone-application

Yup, I already found the source where it raises.

So how close\hide iOS application using Delphi?

I'm new with it.

Yes.

Yes.

But is there a way to move an application at least in background mode like [Home] iPhone hardware button does?

Sure, the easest way will be to hide those [Exit] button from the application in case it doesn't work in iOS.

Why? iOS users know how to move application to the background using Home button. Such functionality does not belong in the iOS application.  Just remove the Exit button or hide it on the iOS and avoid calling problematic code on iOS with compiler directives.

The question is: why do you want your app to be able to do this? As Dalija mentioned, users can easily go to the home screen anyway.

 

Even if you were able to achieve it, if you submit it to the App Store it's highly likely that the app will be rejected. I suggest reading this: https://developer.apple.com/library/archive/qa/qa1561/_index.html

I will do as you mentioned, it sounds correct.
