iphone - Chartboost + Swift + Xcode 6.3：didFailToLoadInterstitial 给出语法错误

Question

我在 Xcode 6.3 中使用了下面的 chartboost swift 代码，并在 didFailToLoadInterstitial 行中出现错误。我在 Xcode 6.2 中没有这个问题。如何在 Xcode 6.3 中解决这个问题？

func applicationDidBecomeActive(application: UIApplication) 
{        
    let kChartboostAppID = "5472ef8f04b01601a1a5814c";
    let kChartboostAppSignature = "5b6222426e68cda48669a1d4d8246d4c3d20db9c";

    Chartboost.startWithAppId(kChartboostAppID, appSignature: kChartboostAppSignature, delegate: self);
    Chartboost.cacheMoreApps(CBLocationHomeScreen)
}

class func showChartboostAds()
{
     Chartboost.showInterstitial(CBLocationHomeScreen);
}

func didFailToLoadInterstitial(location :CBLocation, withError error: CBLoadError)
{

}

Answer 1

这是在 Chartbeat SDK 5.2.0 上为我构建的：

func didFailToLoadInterstitial(location: String!, withError error: CBLoadError) {

}
