ios - 适用于 iOS 的 Facebook SDK : FBSDKShareDialog is not shown

Question

我是 iOS 新手，我想使用适用于 iOS 的 Facebook SDK 分享一个链接。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到共享对话框，并且方法 func sharer(sharer: FBSDKSharing!, didFailWithError error : NSError!) 正在执行，这意味着出了点问题，但我想不通。

提前致谢。

改变这一行

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

进入

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

和我一起工作

这是我使用的委托(delegate)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")
}
