IOS FacebookShare 返回错误“保留”

我尝试过搜索但找不到答案。我已经编写了一个应用程序，我正在尝试将内容分享到 Facebook。基本上我想分享一个网址，也许还有一个引言或标题。

我不断收到一个名为“保留”的错误，但我不确定它的含义或如何修复它。任何帮助都会很棒！

func fbClick() {

    let content = LinkShareContent(url: URL(string: "www.google.com")!)
    showShareDialog(content, mode: .native)

}

func showShareDialog<C: ContentProtocol> (_ content: C, mode: ShareDialogMode = .automatic) {
    let dialog = ShareDialog(content: content)
    dialog.presentingViewController = self
    dialog.mode = mode

    do {
        try dialog.show()
    } catch (let error) {
        self.view.makeToast("Invalid share content. Failed to present share dialog with error \(error)", duration: 3.0, position: .top)
    }
}

弄清楚了。

这条线...

let content = LinkShareContent(url: URL(string: "www.google.com")!)

本来应该是这样的...

let content = LinkShareContent(url: NSURL(string: "https://www.google.com")! as URL)

或者像这样

let content = LinkShareContent(url: NSURL(string: "https://www.google.com")! as URL, quote: quote)
