我在调用游戏中心的成就屏幕时遇到了一些极端的困难。我已经在 iTunes connect 中设置了成就，如果我先通过排行榜访问成就屏幕，它会正常弹出。然而;我希望能够按下特定的成就按钮并直接进入成就屏幕。有人可以帮忙吗？我在互联网上搜索了很多(and read through all of the documentation)。我找到了很多用于实现排行榜的资源，但用于快速实现成就的资源并不多。我的代码如下。对我的最后两个功能有什么建议吗？
override func viewDidLoad() {
super.viewDidLoad()
login()
}
func login() {
println("Game Center Login Called")
let localPlayer = GKLocalPlayer.localPlayer()
// Handle the authentication
localPlayer.authenticateHandler = {(Home: UIViewController!, error: NSError!) -> Void in
if Home != nil {
println("Authentication is being processed.")
self.presentViewController(Home, animated: true, completion: nil)
} else {
println("Player has been successfully authenticated.")
}
}
}
func showLeaderboard() {
let gkScore = GKScore(leaderboardIdentifier: "high_Score_Leader_Board")
gkScore.value = Int64(highscore)
GKScore.reportScores([gkScore], withCompletionHandler: ( { (error: NSError!) -> Void in
if (error != nil) {
// handle error
println("Error: " + error.localizedDescription);
} else {
println("Score reported: \(gkScore.value)")
}
}))
var gcViewController: GKGameCenterViewController = GKGameCenterViewController()
gcViewController.gameCenterDelegate = self
gcViewController.viewState = GKGameCenterViewControllerState.Leaderboards
gcViewController.leaderboardIdentifier = "high_Score_Leader_Board"
self.showViewController(gcViewController, sender: self)
self.presentViewController(gcViewController, animated: true, completion: nil)
}
@IBAction func gameCenterButtoPressed(sender: AnyObject) {
showLeaderboard()
}
func gameCenterViewControllerDidFinish(gcViewController: GKGameCenterViewController!)
{
self.dismissViewControllerAnimated(true, completion: nil)
}
func showAchievements() {
// show Achievements screen
}
@IBAction func achievementButtonPressed(sender: AnyObject) {
// Call show achievements function when button pressed
}
最佳答案
而不是:
gcViewController.viewState = GKGameCenterViewControllerState.Leaderboards
我想你想要的是:
gcViewController.viewState = GKGameCenterViewControllerState.Achievements
