我正在努力在现场实施横幅广告，但它总是报告“线程1：EXC_BREAKPOINT（代码= EXC_ARM_BREAKPOINT，子代码=
Oxdefe），程序停止运行。我在有关iAd（）的另一个问题中引用了T先生的回答。 Swift-ADBannerView“），但仍然无法实现。

代码如下：

 import UIKit
 import SpriteKit
 import iAd
 class GameViewController: UIViewController, ADBannerViewDelegate {

@IBOutlet var adBannerView: ADBannerView
override func viewDidLoad() {
    super.viewDidLoad()
    println("view loaded")

    //iAd
    self.canDisplayBannerAds = true
    self.adBannerView.delegate = self
    self.adBannerView.alpha = 0.0 
     if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {
        // Configure the view.
        let skView = self.view as SKView
        skView.showsFPS = true
        skView.showsNodeCount = true

        /* Sprite Kit applies additional optimizations to improve rendering performance */
        skView.ignoresSiblingOrder = true

        /* Set the scale mode to scale to fit the window */
        scene.scaleMode = .AspectFill

        skView.presentScene(scene)
    }
}
 //iAd
func bannerViewWillLoadAd(banner: ADBannerView!) {


    println("sort of working1")

}

func bannerViewDidLoadAd(banner: ADBannerView!) {


    self.adBannerView.alpha = 1.0 
    println("sort of working2")

}

func bannerViewActionDidFinish(banner: ADBannerView!) {


    println("sort of working3")

}

func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {



    println("sort of working4")
    return true 
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {


}
}

我在Main.storyboard中创建了一个ADBannerView，并将其与@IBOutlet adBannerView链接。

有人帮我弄清楚吗？
