第一步，在storyboard中拖入一个iAd BannerView控件，做好布局就ok了。

第二步，将控件引用到viewController中

第四步，代码部分。

import UIKit
import iAd
class ViewController: UIViewController,ADBannerViewDelegate {

    @IBOutlet weak var MyAd: ADBannerView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        self.canDisplayBannerAds = true
        self.MyAd.delegate = self
        self.MyAd.hidden = true    
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    func bannerViewWillLoadAd(banner: ADBannerView!) {
        NSLog("bannerViewWillLoadAd")
    }

    func bannerViewDidLoadAd(banner: ADBannerView!) {
        NSLog("bannerViewDidLoadAd")
        self.MyAd.hidden = false //now show banner as ad is loaded
    }

    func bannerViewActionDidFinish(banner: ADBannerView!) {
        NSLog("bannerViewDidLoadAd")
        //optional resume paused game code 
    }

    func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
        NSLog("bannerViewActionShouldBegin")   
        //optional pause game code
        return true
    }

    func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
        NSLog("bannerView")
    }
    //... your class implementation code
}

注意：

需要import iAd

以及接口ADBannerViewDelegate

运行之后不会马上显示，与你当前的网络状况有关，有可能会等待一段时间，祝成功！

这是成功后应该出现的情况
