使用iOS9应用程序openURL:sourceApplication:不推荐使用注释

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

所以现在我们应该使用;

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {}

FBSDKApplicationDelegate为sourceApplication参数设置的内容(String)
