swift - swift3 上的 Facebook OpenGraphContent

Question

我尝试将 Open Graph Story 与最新的 Facebook SDK for Swift 集成，但收到错误“无法推断通用参数“内容””

let object: OpenGraphObject = [
    "og:type": "books.book",
    "og:title": "A Game of Thrones",
    "og:description": "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
    "books:isbn": "0-553-57340-3"
]
// Create an action
var action = OpenGraphAction(type: "book.reads")
action["books:book"] = object
// Create the content
var content = OpenGraphShareContent()
content.action = action
content.previewPropertyName = "books:book"
try ShareDialog.show(from: self, content: content) //Here i'm getting "generic parameter 'Content' could not be inferred" 

有人知道解决办法吗？

据我从 commit log 中了解到的，该模块不再维护。相反，请使用 FBSDKShareKit 模块(例如来自 Cocoapods 的 use_frameworks!)。那么你应该能够做到

import FBSDKShareKit

...

// Create an object
let object = FBSDKShareOpenGraphObject.init(properties: [
    "og:type": "books.book",
    "og:title": "A Game of Thrones",
    "og:description": "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.",
    "books:isbn": "0-553-57340-3"
    ])

// Create an action
let action = FBSDKShareOpenGraphAction.init()
action.actionType = "books.reads"
action.setObject(object, forKey: "books:book")

// Create the content

let content = FBSDKShareOpenGraphContent.init()
content.action = action
content.previewPropertyName = "books:book"

FBSDKShareDialog.show(from: self, with: content, delegate: self)
