在游戏中我们经常会为游戏添加广告，但是有时候cocos2dx 添加admob广告会出现错误，那么我们怎样才能解决cocos2dx 添加admob广告错误呢？请看下面。

依照官方教程添加文件及其 frameWork后 发现运行报错 错误如下

clang: error: linker command failed with exit code 1 (use -v to see invocation)

最终通过添加 frameWork搞定  添加了 StoreKit.framework    AdSupport.framework  CoreData.framework .

运行继续报错

clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决方案 add -ObjC to the Other Linker Flags of your application target's build setting。

PS：要弄个全屏的Admob 看了下SDK 似乎没有 就自己动手写

[[GADBannerView alloc] initWithFrame:self.view.bounds];  结果报错 errors = "Ad size will not fit on screen"

但是改为 [[GADBannerView alloc] initWithFrame:CGRectMake(0,0,320,480)];  就可以。 但是同时写了下半屏的CGRect，发现半屏的 frame 显示的不完全，左右被压缩得很厉害，造成了只显示了一个icon和一个按钮。不知道怎么解决。

1. [plain] view plaincopy
2. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
3.  // Override point for customization after application launch.
4. // Add the view controller's view to the window and display.
5. window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];
6. EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]
7. pixelFormat: kEAGLColorFormatRGBA8
8. depthFormat: GL_DEPTH_COMPONENT16
9. preserveBackbuffer: NO
10. sharegroup: nil
11. multiSampling: NO
12. numberOfSamples:0 ];
13.  // Use RootViewController manage EAGLView
14. viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
15. viewController.wantsFullScreenLayout = YES;
16. viewController.view = __glView;
17.  //------------------- Add Admob
18. GADBannerView * bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];
19. bannerView_.rootViewController = viewController;
20. bannerView_.adUnitID = @"a1517648ecd9c44";
21. GADRequest *request = [GADRequest request];
22. request.testing = NO;
23.  //    request.testDevices = [NSArray arrayWithObjects:

25. //                           GAD_SIMULATOR_ID,
26. //
27. //                           @"YOU IPAD IDF",
28. //
29. //                           nil];
30. //----------------------------
31. // Set RootViewController to window
32. if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)
33. {
34.  // warning: addSubView doesn't work on iOS6
35. [window addSubview: viewController.view];
36. }
37. else
38. {
39.  // use this method on ios6
40. [window setRootViewController:viewController];
41. }
42. [viewController.view addSubview: bannerView_];
43. [viewController.view bringSubviewToFront:bannerView_];
44. [window makeKeyAndVisible];
45. [[UIApplication sharedApplication] setStatusBarHidden: YES];
46. [bannerView_ loadRequest: request];
47. cocos2d::CCApplication::sharedApplication()->run();
48. return YES;
49. }

定义一个OC类:

1. [plain] view plaincopy
2. #include <iostream>
3. class AdBridge{
4. public:
5. static void showAdAtTop();
6. static void showAdAtBottom();
7. };
8. [plain] view plaincopy
9. #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
10. #include "MyAdManager.h"
11. #endif
12. void AdBridge::showAdAtTop(){
13. #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
14. [MyAdManager showAddAtTop];
15. #endif
16. }
17. void AdBridge::showAdAtBottom(){
18. #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
19. [MyAdManager showAddAtBottom];
20. #endif
21. }
