未在手机上安装Facebook应用程序时，如何在iOS应用程序中将照片共享到Facebook？

Question

Im using FBSDKShareKit (4.22.1), i'm trying to share photo with the following code:

let photo = FBSDKSharePhoto()
photo1.imageURL = URL(string: "sample url")
photo.isUserGenerated = false  
let photoContent = FBSDKSharePhotoContent()
photoContent.photos = [photo]
FBSDKShareDialog.show(from: self, with: photoContent, delegate: nil)

but it only works when the native Facebook app is installed on the phone. I also tried to show the content with Share Button instead of Share Dialog like:

var shareButton = FBSDKShareButton()
shareButton.shareContent = photoContent
shareButton.center = self.view.center
self.view.addSubview(shareButton)

it didn't work, if app was not installed either.

i want the FBSDK i used in my app, opens Safari when Facebook app is not installed, it opens safari by default for FBSDKShareLinkContent , but not working for FBSDKSharePhotoContent . does anyone know what is the problem?

Answer 1

I have implemented another way to share photos using Graph API . It was very helpful. Here is a link . Just what you need is to take the permissions from the user to publish_actions before posting. Also there is no native facebook app installed. Just got logged in through Browser. I hope this is helpful to you.

Answer 2

Well, I found the answer in Facebook developer website , which is:

Photos

People can share photos from your app to Facebook with the Share Dialog or with a custom interface:

Photos must be less than 12MB in size

People need the native Facebook for iOS app installed, version 7.0 or higher

you can also ask for "publish_actions", you need to login twice, first with readPermission for email, then when user wants to share a post loginWithPublishPermission for "publish_actions". the point is that you have to add "publish_actions" first of all in your Facebook developer account.
