ios - 为什么 FBSDK 共享对话框不适用于图像附件？

Question

我想在 Facebook 上分享图片，为此我这样做了:

let photo: FBSDKSharePhoto = FBSDKSharePhoto()
photo.image = croppedImage
photo.userGenerated = true
photo.caption = "Add Your caption"

let content: FBSDKSharePhotoContent = FBSDKSharePhotoContent()
content.photos = [photo]

FBSDKShareDialog.showFromViewController(self, withContent: content, delegate: nil)

但它没有向我显示 ShareViewController。但是当我尝试这段代码时:

let content: FBSDKShareLinkContent = FBSDKShareLinkContent()
content.contentURL = NSURL(string: "http://")
content.contentTitle = "App Testing"
content.contentDescription = "I'm working over the app!"

如何修复第一个代码段？

Answer 1

我知道这是一个老问题，但以防万一有人遇到同样的问题:

根据documentation ，您需要安装 native Facebook 应用程序才能使用 FBSDKSharePhotoContent，在这种情况下您不能使用 FBSDKShareDialog。

实现几乎相同结果的解决方法是使用 FBSDKShareDialog(仅支持 FBSDKShareLinkContent)，如下所示:

let content: FBSDKShareLinkContent = FBSDKShareLinkContent()
content.imageURL = URL(string: "www.example.com/my_image.jpg")
content.contentURL = URL(string: "www.example.com/target_url")
content.contentTitle = "My Title"
content.contentDescription = "My Description"

let dialog: FBSDKShareDialog = FBSDKShareDialog()
dialog.fromViewController = self
dialog.delegate = self      // make sure to conform to FBSDKSharingDelegate protocol
dialog.shareContent = content
if !dialog.canShow() {
    // fallback to non-native mode
    dialog.mode = .feedBrowser
}
dialog.show()
