如何在swift 3中实现iOS应用程序链接Facebook功能？ [英] How to implement iOS app link Facebook functionality in swift 3?

问题描述

我试过很多方法来实现这一点，但是失败了。

我必须在Facebook上与网址分享信息，点击网址后，将重定向到我的应用的特定页面。

步骤＃1

 让内容：FBSDKShareLinkContent = FBSDKShareLinkContent（）
 content.contentURL = NSURL （string：linkUrl）作为URL！ 
 content.contentTitle =Test
 content.quote =game
 content.contentDescription =这是一个测试游戏来测试Fb共享功能
 content.imageURL = NSURL（string：imgUrl）作为URL！ 
 
 let对话框：FBSDKShareDialog = FBSDKShareDialog（）
 dialog.mode = FBSDKShareDialogMode.native 
 dialog.fromViewController = vc 
 dialog.shareContent = content 
 / /如果没有在CanShow调用之前设置，canShow总是返回YES 
如果！dialog.canShow（）{
 //当没有FB应用程序
时，回退演示文稿dialog.mode = FBSDKShareDialogMode.feedBrowser 
} 
 
 dialog.show（）
  

正在工作并成功分享这个职位。当我点击链接时，它正在重定向到应用程序，没有太多的信息重定向到特定的ViewController。

步骤＃2

  let properties = [
fb：app_id：Fb_id，
og：type：article，
og：title：Test，
og：description：这是一个测试游戏来测试Fb共享功能，
og：image：urlImg，
og：url：linkUrl，
] 
 let对象：FBSDKShareOpenGraphObject = FBSDKShareOpenGraphObject.init（properties：properties）
 
 //创建一个动作
让动作：FBSDKShareOpenGraphAction = FBSDKShareOpenGraphAction（）
 action.actionType =news.publishes
 action.setObject（object，forKey：article）
 
 //创建内容
 let content：FBSDKShareOpenGraphContent = FBSDKShareOpenGraphContent（）
 content.action = action 
 content.previewPropertyName =article
 
 FBSDKShareDialog.show（from：vc，with：content，代表：nil）
  

这里我使用Open Graph发布并成功发布信息。但是，当点击链接时，不要重定向到我的应用程序。

注意：

我没有Web应用程序。

我的目标是通过应用链接分享一篇文章。当点击该链接时，它会打开应用程序，并重定向到特定页面，如果安装了应用程序，否则重定向到AppStore。那么应该是什么样的链接格式，或者如何建立链接来实现这个功能？

请帮忙。

提前感谢

I have tried many ways to achieve this but failed.

I have to share info on facebook with a URL and when clicked on the url, it will redirect to my app's specific page.

step# 1

let content: FBSDKShareLinkContent = FBSDKShareLinkContent()
content.contentURL = NSURL(string: linkUrl) as URL!
content.contentTitle = "Test"
content.quote = "game"
content.contentDescription = "This is a test game to test Fb share functionality"
content.imageURL = NSURL(string: imgUrl) as URL!

let dialog: FBSDKShareDialog = FBSDKShareDialog()
dialog.mode = FBSDKShareDialogMode.native
dialog.fromViewController = vc
dialog.shareContent = content
// if you don't set this before canShow call, canShow would always return YES
if !dialog.canShow() {
    // fallback presentation when there is no FB app
    dialog.mode = FBSDKShareDialogMode.feedBrowser
}

dialog.show()

It is working and successfully sharing the post. When I clicked on the link, it is redirecting to the app, not much info to redirect to a particular ViewController.

Step# 2

let properties = [
    "fb:app_id": "Fb_id",
    "og:type": "article",
    "og:title": "Test",
    "og:description": "This is a test game to test Fb share functionality",
    "og:image" : urlImg,
    "og:url" : linkUrl,
]
let object : FBSDKShareOpenGraphObject = FBSDKShareOpenGraphObject.init(properties: properties)

// Create an action
let action : FBSDKShareOpenGraphAction = FBSDKShareOpenGraphAction()
action.actionType = "news.publishes"
action.setObject(object, forKey: "article")

// Create the content
let content : FBSDKShareOpenGraphContent = FBSDKShareOpenGraphContent()
content.action = action
content.previewPropertyName = "article"

FBSDKShareDialog.show(from: vc, with: content, delegate: nil)

Here I am using Open Graph to post and successfully posted the Info. But con't redirecting to my app when clicked the link.

NB:

I don't have web Application.

My goal is to share a post with a app link. When clicked on that link it will open the app and redirect to a specific page if app is installed, otherwise redirect to the AppStore. So what should be the link format or how can I build the link to achieve this functionality?

Please help.

Thanks in advance

解决方案

Yes, I achieved this functionality by setting up the metadata in the server end.
