ios - Facebook 分享行动 Swift

Question

我不确定我做错了什么。昨天还可以用，但是今天使用的时候就不行了。下面是代码:

        let facebookShareAction = UIAlertAction(title: "Facebook", style: UIAlertActionStyle.Default) { (action) -> Void in
            if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
                // good to go, let's show the twitter composer
                let facebookComposer = SLComposeViewController(forServiceType: ServiceTypeFacebook)
                facebookComposer.setInitialText(course.description)
                facebookComposer.addImage(course.image)
                facebookComposer.addURL(NSURL(string: course.programURL)!)

                self.presentViewController(facebookComposer, animated: true, completion: nil)
            } else {
                // twitter isn't available. alert an error
                self.alert("Facebook Unavaiable", msg: "Go to - Settings > Facebook to set up your Facebook account")
            }
        }

希望有人能帮忙。

服务类型应该是...= SLComposerViewController(forServiceType: SLServiceType....

请尝试以下操作:

    let facebookShareAction = UIAlertAction(title: "Facebook", style: UIAlertActionStyle.Default) { (action) -> Void in
        if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
            // good to go, let's show the twitter composer
            let facebookComposer = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
            facebookComposer.setInitialText(course.description)
            facebookComposer.addImage(course.image)
            facebookComposer.addURL(NSURL(string: course.programURL)!)

            self.presentViewController(facebookComposer, animated: true, completion: nil)
        } else {
            // twitter isn't available. alert an error
            self.alert("Facebook Unavaiable", msg: "Go to - Settings > Facebook to set up your Facebook account")
        }
    }

应该可以解决这个问题
