适用于iOS的Facebook SDK：未显示FBSDKShareDialog

我是iOS的新手，我想使用Facebook SDK for iOS共享链接。 我的代码如下：

@IBAction func shareVoucherUsingFacebook(sender: UIButton) { print("Facebook") let content : FBSDKShareLinkContent = FBSDKShareLinkContent() content.contentURL = NSURL(string: "www.google.com") content.contentTitle = "Content Title" content.contentDescription = "This is the description" let shareDialog: FBSDKShareDialog = FBSDKShareDialog() shareDialog.shareContent = content shareDialog.delegate = self shareDialog.fromViewController = self shareDialog.show() } 

我也实现了FBSDKSharingDelegate方法，但是当我按下这个按钮时，我无法接收共享对话框，并且正在执行方法func sharer(sharer: FBSDKSharing!, didFailWithError error: NSError!) ，这意味着要进行一些操作错了，但我无法弄明白。

提前致谢。

Answer 1

改变这条线

 content.contentURL = NSURL(string: "www.google.com") 

成

 content.contentURL = NSURL(string: "https:\\www.google.com") 

和我一起工作

这是我使用的委托方法

 func sharer(sharer: FBSDKSharing!, didCompleteWithResults results: [NSObject: AnyObject]) { print(results) } func sharer(sharer: FBSDKSharing!, didFailWithError error: NSError!) { print("sharer NSError") print(error.description) } func sharerDidCancel(sharer: FBSDKSharing!) { print("sharerDidCancel") }

如果您在代码中使用NSURL(string:"") ，请记住将http://添加到contentURL 。

 let content : FBSDKShareLinkContent = FBSDKShareLinkContent() content.contentURL = NSURL(string: "http://www.google.com") content.contentTitle = "Content Title" content.contentDescription = "This is the description" FBSDKShareDialog.showFromViewController(self, withContent: content, delegate: self)
