2019-在iOS里添加admob横幅广告示例

1. 下载sdk , 解压
   
   
   
2. 导入项目文件夹:
   
    
   
   
   
3. 在info.plist里加入应用id(不是广告单元id): GADApplicationIdentifier
   
   
   
   
   
4. 设置Build Settings选项
   
   
   
   
   
5. 设置appDelegate:
   

import GoogleMobileAds<br>
<br>
<br>
&nbsp; &nbsp; func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -&gt; Bool {<br>
&nbsp; &nbsp; &nbsp; &nbsp; // Override point for customization after application launch.<br>
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; &nbsp; &nbsp; GADMobileAds.sharedInstance().start(completionHandler: nil)<br>
<br>
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; &nbsp; &nbsp; return true<br>
&nbsp; &nbsp; }<br>
```<br>
6. 设置ViewController:<br>
```<br>
import UIKit<br>
import GoogleMobileAds<br>
<br>
<br>
class ViewController: UIViewController,GADBannerViewDelegate {<br>
&nbsp; &nbsp; var bannerView: GADBannerView!<br>
&nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; override func viewDidLoad() {<br>
&nbsp; &nbsp; &nbsp; &nbsp; super.viewDidLoad()<br>
<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView = GADBannerView(adSize: kGADAdSizeBanner)<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView.rootViewController = self<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView.load(GADRequest())<br>
<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView.delegate = self<br>
<br>
&nbsp; &nbsp; &nbsp; &nbsp; addBannerViewToView(bannerView)<br>
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; }<br>
&nbsp; &nbsp;&nbsp;<br>
&nbsp; &nbsp; func addBannerViewToView(_ bannerView: GADBannerView) {<br>
&nbsp; &nbsp; &nbsp; &nbsp; bannerView.translatesAutoresizingMaskIntoConstraints = false<br>
&nbsp; &nbsp; &nbsp; &nbsp; view.addSubview(bannerView)<br>
&nbsp; &nbsp; &nbsp; &nbsp; view.addConstraints(<br>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [NSLayoutConstraint(item: bannerView,<br>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; attribute: .bottom,<br>

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; relatedBy: .equal,<br>
