適用於iOS的Facebook SDK：未顯示FBSDKShareDialog

Question

我是iOS的新手，我想使用iOS版Facebook SDK共享鏈接。 我的代碼如下：

@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()

}

我還實現了FBSDKSharingDelegate方法，但是當我按下此按鈕時，我無法接收到共享對話框，並且正在執行方法func sharer(sharer: FBSDKSharing!, didFailWithError error: NSError!) ，這意味着有事情要發生了。錯了，但我不知道。

提前致謝。

Answer 1

改變這條線

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

成

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

和我一起工作

這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")
}

Answer 2

如果您在代碼中使用NSURL(string:"") ，只需記住將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)

Answer 3

實現委托方法對我有用
