在导出的Unity Xcode项目上显示Gamecenter

Question

I have an iOS Unity project which has been built and now I have a Xcode project. Now I want to Implement Gamecenter but I just can't seem to find the rootviewcontroller to show the GKLeaderboardViewController. On a native app, I would simply do the following:

#import "AppDelegate.h"

AppDelegate *_delegate = [UIApplication sharedApplication].delegate;
[_delegate.viewController presentModalViewController: leaderboardController animated: YES];

But Unity messes up the code and I only have an AppController.h and an AppController.mm

Anyone has managed to resolve this?

Answer 1

Looking inside the AppController.mm you can find:

if( [_window respondsToSelector:@selector(rootViewController)] )
    _window.rootViewController = controller;

So you can get root view controller by calling

[[UIApplication sharedApplication].keyWindow rootViewController]
