1. 在.h中聲明變量 GADBannerView *adBanner_;

2. 導(dǎo)入框架MessageUK.framework, AudioToolbox.framework, systemConfiguration.framework

3. 在viewDidAppear(或者其他地方）加入如下代碼：

　CGPoint origin = CGPointMake(0.0, 0.0);

　// Use predefined GADAdSize constants to define the GADBannerView.

　self.adBanner = [[[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner

　origin:origin] autorelease];

　// Note: Edit SampleConstants.h to provide a definition for kSampleAdUnitID

　// before compiling.

　self.adBanner.adUnitID = kSampleAdUnitID;

　self.adBanner.delegate = self;

　[self.adBanner setRootViewController:self];

　[self.view addSubview:self.adBanner];

　[self.adBanner loadRequest: [GADRequest request]];

4. 如果有必要實現(xiàn)起delegate方法

　#pragma mark GADBannerViewDelegate impl

　// We've received an ad successfully.

　- (void)adViewDidReceiveAd:(GADBannerView *)adView {

　NSLog(@"Received ad successfully");

　}

　- (void)adView:(GADBannerView *)view

　didFailToReceiveAdWithError:(GADRequestError *)error {

　NSLog(@"Failed to receive ad with error: %@", [error localizedFailureReason]);

　}

5. 在build Setting中，將 Other Linker Flags, add -ObjC to both Debug and Release.
