iAd和admob混用

iAd和admob混用，在收不到iAd广告的时候用admob，一旦收到iAd广告就把admob关闭。这样可以实现在不支持iAd的国家里，开启admob。并不需要判断国家。

判断方法有三点主要事项：
1，同时请求iAd和admob
2，如果收到iAd广告就把admob关了
3，收到admob广告5次了，说明到目前未知还是没有收到iAd，这样说明你收不到iAd广告就可以关闭iAd了

头文件：

#import#import "iAd/ADBannerView.h"#import "GADBannerViewDelegate.h"#import "GADRequest.h"@interface IADHelper : UIViewController{ADBannerView *adView;GADBannerView *adBanner;bool bShowIAD;bool bValidIAD;int receiveAdmob;}@property (retain) UIViewController *presentingViewController;+ (IADHelper *)sharedInstance;- (GADRequest *)createRequest;- (void) hideBannerView;- (void) unhideBannerView;- (void) receiveADmob;@end
