Swift 2.0 Facebook Friend Friend的代码
我一直在寻找Facebook的朋友邀请iOS应用程序的等效Swift代码示例。 但我找不到它们
我明白在Facebook页面上有Objective-C版本https://developers.facebook.com/docs/app-invites/ios 。 不过，因为我从Swift开始，我觉得很难翻译。
有人能指出我的来源吗？ 谢谢。
代码工作：
-In viewDidLoad：
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. 在你的viewController来符合协议委托：
extension InviteFriendsViewController: FBSDKAppInviteDialogDelegate{ func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) { //TODO } func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) { //TODO } }
Facebook Friend邀请Swift 3.0
首先导入FBSDKCoreKit ， FBSDKShareKit并添加委托FBSDKAppInviteDialogDelegate 。 然后，在邀请朋友button点击，添加下面的代码：
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)") }
Benobab的解决scheme是完美的，我只是想补充说，在我的情况下试图运行FBSDKAppInviteDialog.showFromViewController上viewDidAppear工作得更好。
