why my admob doesn't show? - c++

Question

There is no errors in console, and seems everything work. But the bannerView_ just didn't show.
here is my AdMobObject.h
#import "AdMobObject.h"
#import "RootViewController.h"
#import "GADBannerView.h"
#class RootViewController;
#class GADBannerView;
#interface AdMobObject : UIViewController{
RootViewController * viewController;
GADBannerView * bannerView_;
}
+ (AdMobObject *) shared;
- (void) addAdMob;
- ( void) hideAdMob;
#end
here is my AdMobObject.mm
#import "AdMobObject.h"
#import "AppController.h"
#import "RootViewController.h"
#import "EAGLView.h"
#import "cocos2d.h"
#implementation AdMobObject
static AdMobObject* instance;
+(AdMobObject *) shared{
#synchronized(self){
if( instance == nil ){
instance = [[self alloc] init];
}
}
return instance;
}
- (void) addAdMob{
NSLog(#"----------addAdMob");
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenHeight = screenRect.size.height;
CGFloat screenWidth = screenRect.size.width;
viewController.view.frame = CGRectMake(0,0,screenWidth,screenHeight);
[bannerView_ setFrame:CGRectMake(0,
screenHeight-bannerView_.bounds.size.height,
//0,
bannerView_.bounds.size.width,
bannerView_.bounds.size.height)];
bannerView_.adUnitID = #"myadmobid";
bannerView_.rootViewController = viewController;
[viewController.view addSubview:bannerView_];
GADRequest *request = [GADRequest request];
// For testing
request.testDevices = [NSArray arrayWithObjects:#"mydeviceid", nil];
[bannerView_ loadRequest:request];
[viewController.view addSubview:bannerView_];
}
- (void) showAdMob{
}
- (void) hideAdMob{
[bannerView_ setHidden:YES];
}
#end
Then i have a class to manage it:
#interface MyGameCenterManager : NSObject
{
}
+(MyGameCenterManager *) shared;
+(void) addAdMob;
+(void) hideAdMob;
#end
here is the class implementation:
#implementation MyGameCenterManager
static MyGameCenterManager *instance;
+(MyGameCenterManager*)shared{
#synchronized(self){
if(instance == nil){
instance = [[self alloc] init];
}
}
return instance;
}
+ (void) addAdMob
{
[[AdMobObject shared] addAdMob];
}
+ (void) hideAdMob{
[[AdMobObject shared] hideAdMob];
}
Finally, I have cpp class:
include "cocos2d.h"
#include "ScriptingCore.h"
namespace ls{
class GameCenterBridge: public cocos2d::CCObject{
public:
static cocos2d::CCScene* scene();
virtual bool init();
CREATE_FUNC(GameCenterBridge);
void addAdMob();
void hideAdMob();
};
}
I called my class:
ls::GameCenterBridge * class = new ls::GameCenterBridge();
class->addAdMob();
I can see the console log:
----------addAdMob
which means it enter into the addAdMob function. And there has no other errors.
But the banner view just didn't show.
the only way I make it show is to add codes into AppController.mm in didFinishLaunchingWithOptions. But I am just wondering why it won't work for my self created class.

When i was implementing AdMob i showed the ad only when it got loaded from the server. You can achieve this by implementing GADBannerViewDelegate, especially interesting methods are
- (void)adViewDidReceiveAd:(GADBannerView *)bannerView;
- (void)adView:(GADBannerView *)bannerView didFailToReceiveAdWithError:(GADRequestError *)error
This way you can be sure that you received the ad.
