我无法在Stack Overflow上关注其他教程和答案,那么如何在我的游戏中实现GameCenter Leaderboards,在
Swift的SpriteKit中呢？一个人会使用什么代码,它会进入GameScene或GameViewController吗？我已经在iTunes Connect上设置了排行榜.我该怎么做？谢谢！
解决方法
首先,您必须验证播放器：
var localPlayer = GKLocalPlayer.localPlayer()
localPlayer.authenticateHandler = {(viewController : UIViewController!,error : NSError!) -> Void in
if ((viewController) != nil) {
self.presentViewController(viewController,animated: true,completion: nil)
}else{
println((GKLocalPlayer.localPlayer().authenticated))
}
}
然后你可以打开排行榜：
func showLeaderboard() {
var gcViewController: GKGameCenterViewController = GKGameCenterViewController()
gcViewController.gameCenterDelegate = self
gcViewController.viewState = GKGameCenterViewControllerState.Leaderboards
gcViewController.leaderboardIdentifier = "YOUR_BOARD_NAME"
self.showViewController(gcViewController,sender: self)
self.navigationController?.pushViewController(gcViewController,animated: true)
}
func gameCenterViewControllerDidFinish(gcViewController: GKGameCenterViewController!)
{
self.dismissViewControllerAnimated(true,completion: nil)
}
我建议你在视图控制器中做这些.在viewDidAppear上验证播放器,但不是viewDidLoad
