[IOS开发] Cocos2d-x2.2使用Admob插屏广告教程(一)：iOS篇

?1、版别

Cocos2d-x 2.2  
  GoogleAdMobAdsSdkiOS-6.5.1

2、导入

2.1导入头文件和.a文件

并在Librabry Search Paths中添加.a文件的路径 
2.2导入所需iOS构造

AdSupport.framework 
   StoreKit.framework 
   AudioToolbox.framework 
   MediaPlayer.framework 
   MessageUI.framework 
   SystemConfiguration.framework

2.3Linking中添加Other Linker Flags

否则会遇到-[GADObjectPrivate  changeState:]: unrecognized selector sent to instance的疑问 
3、编码完结

自个直接在AppController中参加代码，建议从头封装一个object-c的类，但是完结方法是一样的。
首先要导入GADInterstitila.h头文件，完结GADInterstitialDelegate托付，并定义一个GADInterstitila特色。showInterstitial方法供外部调用用来闪现广告。

1. #import
2. #import "GADInterstitial.h"
3. @class RootViewController;
4. @interface AppController : NSObject  {        UIWindow *window;        RootViewController        *viewController;        GADInterstitial *interstitial_;
5. }
6. @property(nonatomic, retain) GADInterstitial *interstitial;
7. - (void)showInterstitial;
8. @end

拷贝代码

.m文件中主要是delegate函数的完结，interstitial初始化，广告预先请求和广告闪现等方法

1. #pragma mark -
2. #pragma Interstitial Delegate
3. - (void)interstitial:(GADInterstitial *)interstitial
4. didFailToReceiveAdWithError:(GADRequestError *)error {
5. }
6. - (void)interstitialDidReceiveAd:(GADInterstitial *)interstitial {
7. }
8. - (void)interstitialDidDismissScreen:(GADInterstitial *)ad
9. {        [self preloadRequest];
10. }
11. - (void)showInterstitial{        if (self.interstitial.isReady) {        CCLOG("ready");        [self.interstitial presentFromRootViewController:viewController];        } else { CCLOG("not ready"); [self preloadRequest]; }
12. }
13. #pragma mark GADRequest generation
14. -(void)initInterstitial
15. {        // Create a new GADInterstitial each time. A GADInterstitial        // will only show one request in its lifetime. The property will release the        // old one and set the new one.        self.interstitial = [[[GADInterstitial alloc] init] autorelease];        self.interstitial.delegate = self;        // Note: Edit InterstitialExampleAppDelegate.m to update        // INTERSTITIAL_AD_UNIT_ID with your interstitial ad unit id.        self.interstitial.adUnitID = INTERSTITIAL_AD_UNIT_ID;
16. }
17. -(void)preloadRequest
18. {        CCLOG("pre load"); [self initInterstitial]; [self.interstitial loadRequest: [self createRequest]];
19. }
20. // Here we‘re creating a simple GADRequest and whitelisting the application
21. // for test ads. You should request test ads during development to avoid
22. // generating invalid impressions and clicks.
23. - (GADRequest *)createRequest {        GADRequest *request = [GADRequest request];        // Make the request for a test ad. Put in an identifier for the simulator as        // well as any devices you want to receive test ads.        request.testDevices =        [NSArray arrayWithObjects: // TODO: Add your device/simulator test identifiers here. They are // printed to the console when the app is launched. nil];        return request;
24. }

跟android不一样的是，interstitial目标每次request时都必须从头初始化。 
完好的.m文件：

1. #import "AppController.h"
2. #import "EAGLView.h"
3. #import "cocos2d.h"
4. #import "AppDelegate.h"
5. #import "RootViewController.h"
6. #define INTERSTITIAL_AD_UNIT_ID @"YOUR_OWN_ID"
7. @implementation AppController
8. @synthesize interstitial = interstitial_;
