我目前在我的iOS目标中使用Game Center,但没有在tvOS目标中工作。
我已经添加了排行榜图像并将标识符放在Xcode中:
这是我用来调出排行榜并启动播放器的课程。它被称为GameKitHelper.swift:
import UIKit
import Foundation
import GameKit
let PresentAuthenticationViewController = "PresentAuthenticationViewController"
class GameKitHelper: NSObject {
static let sharedInstance = GameKitHelper()
var authenticationViewController: UIViewController?
var gameCenterEnabled = false
func authenticateLocalPlayer() {
//1
let localPlayer = GKLocalPlayer()
localPlayer.authenticateHandler = {(viewController, error) in
if viewController != nil {
//2
self.authenticationViewController = viewController
NSNotificationCenter.defaultCenter().postNotificationName(PresentAuthenticationViewController, object: self)
}
else if error == nil {
//3
self.gameCenterEnabled = true
}
}
}
func reportAchievements(achievements: [GKAchievement], errorHandler: ((NSError?)->Void)? = nil) {
guard gameCenterEnabled else {
return
}
GKAchievement.reportAchievements(achievements, withCompletionHandler: errorHandler)
}
func showGKGameCenterViewController(viewController: UIViewController) {
guard gameCenterEnabled else {
return
}
//1
let gameCenterViewController = GKGameCenterViewController()
//2
gameCenterViewController.gameCenterDelegate = self
//3
viewController.presentViewController(gameCenterViewController, animated: true, completion: nil)
}
func saveHighScore(identifier: String, score: Int) {
if (GKLocalPlayer.localPlayer().authenticated) {
let scoreReporter = GKScore(leaderboardIdentifier: identifier)
scoreReporter.value = Int64(score)
let scoreArray:[GKScore] = [scoreReporter]
GKScore.reportScores(scoreArray, withCompletionHandler: {
error -> Void in
if (error != nil) {
print("error")
}
else {
print("Posted score of \(score)")
}
})
}
}
}
extension GameKitHelper: GKGameCenterControllerDelegate {
func gameCenterViewControllerDidFinish(gameCenterViewController: GKGameCenterViewController) {
gameCenterViewController.dismissViewControllerAnimated(true, completion: nil)
}
}
NavigationController类:
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self,
selector: Selector("showAuthenticationViewController"),
name: PresentAuthenticationViewController,
object: nil)
GameKitHelper.sharedInstance.authenticateLocalPlayer()
}
func showAuthenticationViewController() {
let gameKitHelper = GameKitHelper.sharedInstance
if let authenticationViewController = gameKitHelper.authenticationViewController {
topViewController?.presentViewController(authenticationViewController,
animated: true,
completion: nil)
}
}
deinit {
NSNotificationCenter.defaultCenter().removeObserver(self)
}

确保您拥有" Apple TV Dashboard Image"在您应用的资产目录中。仪表板图稿应为923x150,透明度,并且不需要分层,因为用户无法选择它。
tvOS Human Interface Guidelines声称信息中心图稿是可选的,但根据我的经验GKGameCenterViewController
,如果您没有,则会拒绝显示。
