iOS: GetUserId has Null Exception, Leads to Crash about play-games-plugin-for-unity HOT 6 CLOSED

FYI, also had this issue with the GetUserDisplayName function.

My workaround/hack at the moment is to cache the user ID and display name in Unity after retrieving them for the first time, instead of calling down to native each time. I'm not too happy about that solution, and it is a bit unsettling because the GPGPlayer instance being deallocated seems to occur just a couple seconds after log in...not sure why it is being deallocated.

I've also found that using the following sort of code in the "playerId" property in GPGSManager.m seems to work well:

- (NSString*) playerId
{
    GPGPlayerModel *playerModel = [[[GPGManager sharedInstance] applicationModel] player];
    GPGPlayer *localPlayer = playerModel.localPlayer;
    return localPlayer.playerId;
}

Is there a problem with doing it this way? It seems that GPGPlayer is deallocated after being created at sign in, so retrieving the player object again on demand might do the trick. But I'm not so hot with obj-c, so maybe this is a terrible way to do things.

I'm wondering if perhaps the right answer here would be to declare this as a "copy" style property. Seems odd that the playerID would be deallocated though, because you still have a strong pointer pointing to it (even if its parent object goes away.) But let me chat with Bruno and we can investigate...

I had this issue as well, your code seems to have moved the error elsewhere. The SDK still crashes on sign in though.

Will fix this soon! Thanks for reporting.
