Swift Game Center身份驗證

Question

我在Game Center中驗證有問題。我看不出我的代碼有什麼問題。

func authenticateLocalPlayer(){ 
    var localPlayer = GKLocalPlayer() 
    localPlayer.authenticateHandler = {(viewController, error) -> Void in 
     if (viewController != nil) { 
      self.presentViewController(viewController, animated: true, completion: nil) 
     }else{ 
      println((GKLocalPlayer().authenticated)) 
     } 
    } 
} 

我調用這個函數在側面GameViewController

self.authenticateLocalPlayer() 

我每次運行應用程序時，我得到一個錯誤的回報。我的設備上有Settings> Game Center> Developer> SandBox> ON ，但仍然無法在我的應用內進行身份驗證。

Answer 1

這個問題與GKLocalPlayer（）和Swift中的錯誤有關。請看到我從幾個星期前給這個很詳細的解答：

Swift - Game Center not available

Answer 2

您可以使用，我在github上來自法國製作iOS遊戲中心的簡單類 https://github.com/DaRkD0G/Easy-Game-Center-Swift

消息，聖誕快樂

開始

（1）添加的FrameWork GameKit.framework

（2）創建兩個文件：

GKLocalPlayerHack.h

#import <GameKit/GameKit.h> 
@interface GKLocalPlayerHack : NSObject 
GKLocalPlayer *getLocalPlayer(void); 
@end 

GKLocalPlayerHack.m

#import "GKLocalPlayerHack.h" 
@implementation GKLocalPlayerHack 
GKLocalPlayer *getLocalPlayer(void) { 
    return [GKLocalPlayer localPlayer]; 
} 
@end 

（3）在您的斯威夫特橋接報.h（Objectic-c import）

#import "GKLocalPlayerHack.h"
