c++ - 在cocos2d-x项目中使用admob和objective-c时出现的问题

Question

我使用 pod 来初始化我的项目，并尝试在我的 cocos 游戏上添加横幅。我已经完成了游戏，但每当我在函数中使用“adBanner”时:didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

我遇到链接问题。谁能帮忙？

![在此处输入图片描述][1]

错误信息:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_GADBannerView", referenced from:
      objc-class-ref in AppController.o
  "_kGADAdSizeBanner", referenced from:
      -[AppController application:didFinishLaunchingWithOptions:] in AppController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

代码:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];

    // Use RootViewController to manage CCEAGLView
    _viewController = [[RootViewController alloc]init];
    _viewController.wantsFullScreenLayout = YES;


    // Set RootViewController to window
    if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)
    {
        // warning: addSubView doesn't work on iOS6
        [window addSubview: _viewController.view];
    }
    else
    {
        // use this method on ios6
        [window setRootViewController:_viewController];
    }

    [window makeKeyAndVisible];

    [[UIApplication sharedApplication] setStatusBarHidden:true];

    //==============================banner================================
    CGPoint origin = CGPointMake(0.0, _viewController.view.frame.size.height - kGADAdSizeBanner.size.height);
    self.adBanner = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner origin:origin];
    self.adBanner.adUnitID = @"ca-app-pub-3940256099942544/2934735716";

在 Build Settings -> Linking 中。找到“其他链接器标志”。为构建和发布设置 -Objc。

确保按照 admob 文档正确设置所有其他框架。
