ios - 快速发布到 Facebook 不起作用？

Question

我正在尝试将照片发布到 Facebook，使用以下代码可以正常工作:

   func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

        self.selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage

        var photo = FBSDKSharePhoto()
        photo.image = self.selectedImage
        photo.userGenerated = true

        var content = FBSDKSharePhotoContent()
        content.photos = [photo]


        self.dismissViewControllerAnimated(true, completion: nil)

        shareDialog.fromViewController = self
        shareDialog.shareContent = content
        shareDialog.show()

}

但是，这仅在用户下载了 facebook 应用程序时有效。否则它不会打开网络浏览器来分享照片，即使 facebook 声明:

The Share Dialog switches to the native Facebook for iOS app, then returns control to your app after a post is published. If someone doesn't have Facebook app installed it will automatically falls back to a web-based dialog.

有什么建议吗？感谢回答，谢谢。

你可以试试这个:

func postToFacebook(image: UIImage!) {
    var SocialMedia :SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
    SocialMedia.completionHandler = {
        result -> Void in
        var getResult = result as SLComposeViewControllerResult;
        switch(getResult.rawValue) {
        case SLComposeViewControllerResult.Cancelled.rawValue: println("Cancelled")
        case SLComposeViewControllerResult.Done.rawValue: println("It's Work!")
        default: println("Error!")
        }
        self.dismissViewControllerAnimated(true, completion: nil)
    }
    self.presentViewController(SocialMedia, animated: true, completion: nil)
    SocialMedia.setInitialText("...")
    SocialMedia.addImage(image)
}
