使用swift添加Facebook时出现ParseUI错误

Question

所以我按照解析网站(https://www.parse.com/docs/ios_guide#fbusers/iOS)上的步骤添加Facebook登录.但是Xcode给了我错误'() - > FBSDKApplicationDelegate!' 在我的app委托文件中没有名为"application"的成员用于以下代码行

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

我错过了什么？

Answer 1

看起来您缺少sharedInstance的括号.

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