iOS How to get Firebase Device Token

[Lena]

Hi.
In Android project all fine but in IOS FDeviceToken always empty.
Where could be the problem?

Code: Select all

#include <System.PushNotification.hpp>
//***
private:   // User declarations
   String FDeviceID;
   String FDeviceToken;

   TPushService * FPushService;
   TPushServiceConnection * FPushServiceConnection;

   void __fastcall OnReceiveNotificationEvent(TObject *Sender, TPushServiceNotification* const ANotification);
   void __fastcall OnServiceConnectionChange(TObject *Sender, TPushService::TChanges AChange);
   void __fastcall PushServiceRegister();
   void __fastcall RegisterDevice();


Code: Select all

#if defined(__APPLE__) && (defined(__arm__) || defined(__arm64__))
#include <FMX.PushNotification.IOS.hpp>

namespace Fmx {
 namespace Pushnotification {
  namespace Ios {
   _INIT_UNIT(Fmx_Pushnotification_Ios);
   }
  }
}

#endif

__fastcall TForm1::TForm1(TComponent* Owner) : TForm(Owner)
{
  PushServiceRegister();
}

void __fastcall  TForm1::PushServiceRegister()
{

    FPushService = nullptr;
    FPushServiceConnection = nullptr;

   #if defined(__ANDROID__)
    FPushService = TPushServiceManager::Instance->GetServiceByName(TPushService_TServiceNames_GCM);
    if(FPushService)
      FPushService->AppProps[TPushService_TAppPropNames_GCMAppID] = FAndroidServerKey;
   #endif
   #if defined(__APPLE__) && (defined(__arm__) || defined(__arm64__))
      FPushService = TPushServiceManager::Instance->GetServiceByName(TPushService_TServiceNames_APS);
   #endif

   if(FPushService)
     {

      FPushServiceConnection = new TPushServiceConnection(FPushService);
      FPushServiceConnection->OnChange = &OnServiceConnectionChange;
      FPushServiceConnection->OnReceiveNotification = &OnReceiveNotificationEvent;
      FPushServiceConnection->Active = true;

      FDeviceID = FPushService->DeviceIDValue[TPushService_TDeviceIDNames_DeviceID];// OK!
      FDeviceToken = FPushService->DeviceTokenValue[TPushService_TDeviceTokenNames_DeviceToken];//Problem in IOS!

      if(FDeviceID != "" && FDeviceToken != "")
       {
        RegisterDevice();
       }

     }
}

I found this:

https://community.embarcadero.com/answe ... nvey-parse

On iOS, the first time i call function below, I get a empty string. If I wait a second and try again, I get the right device token. So apparently, on iOS, activating PushServiceConnection (for the first time) will start a background process that takes some time before it results in a device token. This is a little bit mystic.

So, try calling FPushService->DeviceTokenValue[DeviceToken] in a loop until it returns a non-blank string, or until a few seconds have elapsed, whichever occurs first.

or until a few seconds have elapsed

I use for this OnServiceConnectionChang:

Code: Select all

void __fastcall TForm1::OnServiceConnectionChange(TObject *Sender, TPushService::TChanges AChange)
{
   Label2->Text = L"Bihgo!";
   if (AChange.Contains(TPushService::TChange::DeviceToken) && (FPushServiceConnection))
   {
    Label2->Text = L"Again Bingo...";
    FDeviceID = FPushService->DeviceIDValue[TPushService_TDeviceIDNames_DeviceID];
    FDeviceToken =   FPushService->DeviceTokenValue[TPushService_TDeviceTokenNames_DeviceToken];

      if(FDeviceID != "" && FDeviceToken != "")
       {
        Label2->Text = L"Problem! I do not get here.";
        RegisterDevice();
       }

   }
}

FDeviceToken in ios is empty.

[rlebeau]

All my code:

Did you verify that the OnServiceConnectionChange event is being fired at all?

Did you try what I suggested earlier (using a simple loop instead of the event)? For example:

Code: Select all

FDeviceToken = FPushService->DeviceTokenValue[TPushService_TDeviceTokenNames_DeviceToken];

#if defined(__APPLE__) && (defined(__arm__) || defined(__arm64__))
if (FDeviceToken == _D(""))
{
    for (int i = 0; i < 5; ++i)
    {
        Sleep(1000); // <-- or whatever the iOS equivalent is...
        FDeviceToken = FPushService->DeviceTokenValue[TPushService_TDeviceTokenNames_DeviceToken];
        if (FDeviceToken != _D(""))
            break;
    }
}
#endif

...


FDeviceToken in ios is empty.

If you can't get the token to work, then you will have to take up the issue with Embarcadero directly. File a bug report or open a Support case.

Yes. I see text in Label2:

Code: Select all

void __fastcall TForm1::OnServiceConnectionChange(TObject *Sender, TPushService::TChanges AChange)
{
   if (AChange.Contains(TPushService::TChange::DeviceToken) && (FPushServiceConnection))
   {
    FDeviceID = FPushService->DeviceIDValue[TPushService_TDeviceIDNames_DeviceID];
    FDeviceToken =   FPushService->DeviceTokenValue[TPushService_TDeviceTokenNames_DeviceToken];
    Label2->Text = L"TEST before if";//OK
      if(FDeviceID != "" && FDeviceToken != "")
       {
        Label2->Text = L"TEST in if";//problem not fired
        RegisterDevice();
       }

   }
}

Thank you I try but FDeviceToken still blank.

If you can't get the token to work, then you will have to take up the issue with Embarcadero directly. File a bug report or open a Support case.

Thank you. I will post in support and in Embarcadero forum. Maybe idera staff there read.

С++ Buillder still dead product to use notifications in IOS 10.
They do not work basic functions.

[Lena]

I set correct provisioning profile and got FDeviceToken.
Now FDeviceToken is not NULL.
But when I try send push from Firebase to my IOS10 devise notthing happens.
Can sombody show how get push from FCM to IOS10 devise?
