adMob iAd整合，随机根据网络状况自动显示。

最近找整合的代码，找到的都不对，有个大概对的，但要奔溃退出，只要两个单独弄。

adMob 下载好sdk，导入进去，iAd的加入iad framework.

使用方法，在viewController viewDidAppear内添加

IADView* adView = [IADView sharedInstance];
    [adView createAdBannerView:self.view TOP:0];

IADView

#import "iAd/ADBannerView.h"

#import "GADRequest.h"

@interface IADView : UIViewController<ADBannerViewDelegate,GADBannerViewDelegate>{
    ADBannerView *adView;
    GADBannerView *adBanner;
    bool bShowAD;
