iOS应用添加Google广告

关于广告（5步）
google admob广告
第一要注册一个google ID for self.adBanner.adUnitID
创建ID具体操作介绍：

进apps.admob.com注册admob账号:账号由AdSense账号和AdWords账号组成

第二要下载adk
https://developers.google.com/mobile-ads-sdk/docs/admob/ios/download

第三是引入这个framework到工程中
然后引入头文件#import 到viewcontroller上

第四 见代码：
示例代码github地址:https://github.com/googleads/googleads-mobile-ios-examples
官方说明文档：https://developers.google.com/mobile-ads-sdk/docs/admob/ios/quick-start#_adc=ww-zh-Hans-et-HC

一般会在table的footer上加上这个广告
@property (nonatomic, strong) GADBannerView *adBanner;

• (void)resetTableFootView {

  UIView * view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];

  [self showiAdViewIfNeed:view];

  self.table.tableFooterView = view;

}

• (void)showiAdViewIfNeed:(UIView *)containerView {

  if (containerView == NULL) {

    return;
  

  }

  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

  [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

  NSString *dateString =@"2019-04-01 00:00:00”;//在这个时间之前的就显示广告，否则不显示

  NSDate *validDate = [dateFormatter dateFromString:dateString];

  BOOL isHideiAd = [DateUtil dateCalendarBeforeToday:validDate];

  if (!isHideiAd) {

    CGPoint origin = CGPointMake(0.0, 0.0);
  
    self.adBanner = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner origin:origin];
  
    self.adBanner.adUnitID = @"ca-app-pub-5056085843442632/2662170106";
  
    self.adBanner.delegate = self;//GADBannerViewDelegate
  
    [self.adBanner setRootViewController:self];
  
    [self.view addSubview:self.adBanner];
  
    [self.adBanner loadRequest: [GADRequest request]];
  
    containerView.frame = CGRectMake(containerView.frame.origin.x,
  
                                     containerView.frame.origin.y,
  
                                     containerView.frame.size.width,
  
                                     containerView.frame.size.height + self.adBanner.frame.size.height+5);
  
    [containerView addSubview:self.adBanner];
  

  }

}

第五实现两个delegate方法，在请求google广告之后的成功&失败回调

• (void)adViewDidReceiveAd:(GADBannerView *)view {

  self.adBanner.hidden = NO;

}

• (void)adView:(GADBannerView *)view didFailToReceiveAdWithError:(GADRequestError *)error {

  self.adBanner = nil;

  self.table.tableFooterView = nil;

}
