不知道该怎么做才能添加Game Center排行榜

Question

I tried to add a Game Center leaderboard, first setting it on iTunes Connect but when I have to write the code in Xcode I don't know what I have to do. I want to open the leaderboard with a shake gesture and for that I will use this code in the ViewController.m file:

-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if(event.subtype == UIEventSubtypeMotionShake) {
       // Code you want to run when the shake began
       }
}

Is that code right? And please can anyone help me what I have to do for appear the leaderboard when shaking?

Answer 1

1. Enable GameCenter in the Project's capabilities tab
2. Create a GKGameCenterViewController instance
3. Set the appropriate viewState property
4. If necessary, set the gameCenterDelegate property

5. Present the VC:

    GKGameCenterViewController *vc = [GKGameCenterViewController new]; vc.viewState = GKGameCenterViewControllerStateLeaderboards; vc.gameCenterDelegate = self; [self presentViewController:vc animated:YES];
