iOS notifications sporadic (FMX)

  

Following the Embarcadero docs at this link i’m testing notifications on iOS (in FMX app built with C++). I’ve done the follownig:

Added #include <System.Notification.hpp> to the header file
Set FMLocalNotificationPermission to true
Dropped TNotificationCenter component on the form

Then, i put the following code in a button click:

void __fastcall TForm1::ScheduleNotificationClick(TObject *Sender)
{
if (NotificationCenter1->Supported()) {
TNotification *myNotification = NotificationCenter1->CreateNotification();
__try {
myNotification->Name = “MyNotification”;
myNotification->AlertBody = “C++ for your mobile device is here!”;
// Fire in 10 seconds
myNotification->FireDate = Now() + EncodeTime(0, 0, 10, 0);
// Send notification to the notification center
NotificationCenter1->ScheduleNotification(myNotification);
}
__finally {
myNotification->DisposeOf();
}
}
}

Once in a while it works…but rarely and never more than once. Most of the time it doesn’t at all (repeated deleting and reinstall of app).

Next, i tried the “Present the Notification Message Immediately” code they provide:

void __fastcall TForm1::PresentNotificationClick(TObject *Sender)
{
if (NotificationCenter1->Supported()) {
TNotification *myNotification = NotificationCenter1->CreateNotification();
__try {
myNotification->Name = “MyNotification”;
myNotification->AlertBody = “C++ for your mobile device is here!”;
// Set Icon Badge Number (for iOS) or message number (for Android) as well
myNotification->Number = 18;
myNotification->EnableSound = False;
// Send notification to the notification center
NotificationCenter1->PresentNotification(myNotification);
}
__finally {
myNotification->DisposeOf();
}
}
}

Nothing happens at all with this code. I’ve tried this from scratch several times and i’m as sure as i can be that i’m coding it per their examples. I’m using 10.3 (Embarcadero® C++Builder 10.3 Version 26.0.32429.4364). I would think my code has a problem except once in blue moon it works.

My target is iPhone running 12.1.4 and i’ve tried building with SDK11.4 and SDK12.0, no difference. When i first run app i get the “allow or don’t allow” popup and my app subsequently shows up in the Notification settings – just doesn’t work.
