Hi, after pulling my hair out for a few days, I finally figured it out. These instructions will also work for the Storekit as well. For the StoreKit, you would just use storekit delegates like the leaderboard delegate.
Get the example native code sample from the resources here and do the following. This isn’t the most elegant code, but it does the job. One thing I did notice is, the leaderboard will not work when debugging. But works just fine when launched on its own.
Add the GameKit framework.
The next part is the key to adding subviews.
In AppController.mm
controller.view = view;
//[_window addSubview:view];
//CUSTOM VIEW CONTROLLER UIViewController
UIViewController *vc = [[UIViewController alloc] init];
[vc.view addSubview:view];
[vc.view setTag:999];
[_window addSubview:vc.view];
Next I made a class to deal with game center functions, in this case I’m only working with the leaderboard.
