ios - 完成社交分享后开始Segue

Question

我想让用户在社交框架的帮助下分享我的应用中的一些帖子。但是在社交框架中的发布按钮之后，segue 并没有开始。我该如何处理？

var shareToFacebook : SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
shareToFacebook.addImage(self.Img.image)
self.presentViewController(shareToFacebook, animated: true, completion: nil)
self.performSegueWithIdentifier("goToStarting", sender: self)

Answer 1

你必须在这个方法中呈现 View Controller

var completionHandler: SLComposeViewControllerCompletionHandler!

你可以像这样使用上面的方法

var shareToFacebook : SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
shareToFacebook.addImage(self.Img.image)
shareToFacebook.completionHandler = {
    (result:SLComposeViewControllerResult) in

    }
self.presentViewController(shareToFacebook, animated: true, completion: nil)
self.performSegueWithIdentifier("goToStarting", sender: self)
