您需要实现revMobDelegate并使用revmobAdDidReceive:

You need to implement the revMobDelegate and use revmobAdDidReceive:

@interface MyAdClass : NSObject <RevMobAdsDelegate>
...

@implementation MyAdClass
-(void) prepare {
    ...
    ad = [[[RevMobAds session] bannerView] retain];
    ad.delegate = self;
    [ad loadAd];
    ...
} 

- (void)revmobAdDidReceive {
    NSLog(@"ad received");
    ...
}

您可以在 http://sdk.revmob.com/上找到RevMobAdsDelegate文档.ios-api/Protocols/RevMobAdsDelegate.html
