GameCenterManager（ios 第三方框架）----

1、启动GameCenter

1.1、初始化GameCenterManager

#import "GameCenterManager.h"
 [GameCenterManager sharedManager] setupManagerAndSetShouldCryptWithKey：@“YourKey”];  

1.2、设置GameCenter代理

@interface XGSDKImpl ()<GameCenterManagerDelegate>{
   }

[[GameCenterManager sharedManager] setDelegate:self];

#pragma gamecenter delegate
//要求调用代理时，用户需要使用GameCenter登录视图控制器认证
- (void)gameCenterManager:(GameCenterManager *)manager authenticateUser:(UIViewController *)gameCenterLoginController
{
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:gameCenterLoginController animated:YES completion:nil];
}

2、获取登陆GameCenter产生的playerId

- (NSString *)getTempAccountWithGameCenter
{
    BOOL available = [[GameCenterManager sharedManager] checkGameCenterAvailability];
    NSString *playid = nil;
    if (available) {
        playid = [[GameCenterManager sharedManager] localPlayerId];
    }
    return [[NSString stringWithFormat:@"%@",playid] md5];
;
}

3、总结

这只是启用GameCenterManager登陆以及获取其登陆id的基本步骤，当然那GameCenterManager中还有其它许多的功能，所以附上GameCenterManager源文档.
