Swift Facebook 好友邀请 2.0 代码

Question

我一直在为 iOS 应用的 Facebook 好友邀请寻找等效的 Swift 代码示例。但是我找不到。

我了解到 Facebook 页面 https://developers.facebook.com/docs/app-invites/ios 上有 Objective-C 版本。但是，因为我是从 Swift 开始的，所以我觉得很难翻译。

有人可以给我指出来源吗？谢谢。

Answer 1

代码有效：

-在 viewDidLoad 中：

let content = FBSDKAppInviteContent()
content.appLinkURL = NSURL(string: "https://test/myapplink")
content.appInvitePreviewImageURL = NSURL(string: "https://test/myapplink")
// Old Way, now depreciated :
//FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
//New way : 
        FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
// Do any additional setup after loading the view.

-在您的 viewController 中遵守协议委托：

extension InviteFriendsViewController: FBSDKAppInviteDialogDelegate{
    func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
        //TODO
    }
    func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
        //TODO
    }
}

Benobab 解决方案是完美的，我只是想补充一点，在我的案例中尝试运行 FBSDKAppInviteDialog.showFromViewController 在 viewDidAppear 上效果更好。

Facebook 好友邀请 Swift 3.0

首先，导入FBSDKCoreKit、FBSDKShareKit并添加委托FBSDKAppInviteDialogDelegate。然后，点击邀请好友按钮，添加以下代码：

let inviteDialog:FBSDKAppInviteDialog = FBSDKAppInviteDialog()
if(inviteDialog.canShow()){
    let appLinkUrl:NSURL = NSURL(string: "http://yourwebpage.com")!
    let previewImageUrl:NSURL = NSURL(string: "http://yourwebpage.com/preview-image.png")!

    let inviteContent:FBSDKAppInviteContent = FBSDKAppInviteContent()
    inviteContent.appLinkURL = appLinkUrl as URL!
    inviteContent.appInvitePreviewImageURL = previewImageUrl as URL!

    inviteDialog.content = inviteContent
    inviteDialog.delegate = self
    inviteDialog.show()
}

然后，添加FBSDKAppInviteDialogDelegate下面的方法：

func appInviteDialog (_ appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [AnyHashable : Any]!) {
    let resultObject = NSDictionary(dictionary: results)

    if let didCancel = resultObject.value(forKey: "completionGesture")
    {
        if (didCancel as AnyObject).caseInsensitiveCompare("Cancel") == ComparisonResult.orderedSame
        {
            print("User Canceled invitation dialog")
        } 
    } 
} 
func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: Error!) {
    print("Error tool place in appInviteDialog \(error)")
}
