IOS版Cocos2d-x2.2使用移動廣告聚合平臺集成插屏廣告教程

一、版本
Cocos2d-x 2.2  
GoogleAdMobAdsSdkiOS-6.5.1

二、導入
2.1 導入頭文件和.a文件
並在Librabry Search Paths中添加.a文件的路徑

2.2 導入所需IOS框架
AdSupport.framework
StoreKit.framework
AudioToolbox.framework
MediaPlayer.framework
MessageUI.framework
SystemConfiguration.framework

2.3 Linking中添加Other Linker Flags
不然會遇到-[GADObjectPrivate  changeState:]: unrecognized selector sent to instance的問題。

三、編碼
首先要導入GADInterstitila.h頭文件，實現GADInterstitialDelegate委託，並定義一個GADInterstitila屬性。showInterstitial方法供外部調用用來顯示廣告。
#import <UIKit/UIKit.h>
#import "GADInterstitial.h"

@class RootViewController;

@interface AppController : NSObject <UIApplicationDelegate,GADInterstitialDelegate> {  
UIWindow *window;  
RootViewController         *viewController;  
GADInterstitial                *interstitial_;
}
@property(nonatomic, retain) GADInterstitial *interstitial;

- (void)showInterstitial;

@end

.m文件中主要是delegate函數的實現，interstitial初始化，廣告預先請求和廣告顯示等方法
#pragma mark -#pragma Interstitial Delegate
- (void)interstitial:(GADInterstitial *)interstitial
didFailToReceiveAdWithError:(GADRequestError *)error {
 
}

- (void)interstitialDidReceiveAd:(GADInterstitial *)interstitial {  

}

- (void)interstitialDidDismissScreen:(GADInterstitial *)ad
{  

[self preloadRequest];

}

}
#pragma mark GADRequest generation
{
// 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;

}
-(void)preloadRequest
{  
CCLOG("pre load");   
[self initInterstitial];   
[self.interstitial loadRequest: [self createRequest]];

}

// Here we're creating a simple GADRequest and whitelisting the application
// for test ads. You should request test ads during development to avoid
// generating invalid impressions and clicks.

- (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;
}

跟android不一樣的是，interstitial對象每次request時都必須從新初始化。
完整的.m文件：
#import "AppController.h"
#import "EAGLView.h"#import "cocos2d.h"
#import "AppDelegate.h"
#import "RootViewController.h"

#define INTERSTITIAL_AD_UNIT_ID @"YOUR_OWN_ID"
@implementation AppController
@synthesize interstitial = interstitial_;
#pragma mark -
#pragma mark Application lifecycle
// cocos2d application instancestatic AppDelegate s_sharedApplication;

- (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]];    

// Init the EAGLView  
EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]                   
pixelFormat: kEAGLColorFormatRGB565

// Use RootViewController manage EAGLView   
viewController=[[RootViewController alloc] initWithNibName:nil bundle:nil];  
viewController.wantsFullScreenLayout = YES;  
viewController.view = __glView;

// 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];
//[self initInterstitial];//每次request都要從新初始化  

[self preloadRequest];  cocos2d::CCApplication::sharedApplication()->run();
  return YES;

四、調用
