所以我正在尝试将 GameKit 与 Cocos2D 一起使用，这样当用户单击多人菜单项时，它将显示 GKPeerPickerController。然而，我遇到了一些障碍。它似乎不想编译。但是，它不会在我的选择器中的代码中给我一个错误。无论如何，这是代码...

@implementation GameOverLayer
- (id) init 
{
    self = [super init];
    if (self != nil) 
    {
        [CCMenuItemFont setFontSize:20];
        [CCMenuItemFont setFontName:@"Helvetica"];
        CCMenuItem *start = [CCMenuItemFont itemFromString:@"Play Again!" target:self selector:@selector(startGame:)];
        CCMenuItem *connect = [CCMenuItemFont itemFromString:@"Multiplayer" target:self selector:@selector(connect:)];
        CCMenu *menu = [CCMenu menuWithItems:start,connect, nil];
        [menu alignItemsVertically];
        [self addChild:menu];
    }
    return self;
}
-(void)startGame: (id)sender 
{
    [[CCDirector sharedDirector] replaceScene: [HelloWorld scene]];
}

-(void)connect: (id)sender
{
    GKPeerPickerController *peerPicker;
    peerPicker = [[GKPeerPickerController alloc] init];

    peerPicker.delegate = self;
    peerPicker.connectionTypesMask = GKPeerPickerConnectionTypeOnline | GKPeerPickerConnectionTypeNearby;

    [peerPicker show];
}
@end

我收到的错误消息是...

".obj_class_name_GKPeerPickerController", referenced from:
Literal-Pointer@_OBJC@_cls_refs@GKPeerPickerController in GameOverScene.o
Symbol(s) not found
Collect2: id returned 1 exit status

有任何想法吗？

将 GameKit 框架添加到您的项目中，或者如果它已经存在，请确保选中其目标复选框。
