iOS Facebook分享视频Swift

Question

我正在寻找一种在Facebook上分享我的应用程序视频的方法。 我将SDK安装到了Facebook，并按照说明进行操作，但是我不明白为什么我不能分享我的视频。

let fbVideo:FBSDKShareVideo = FBSDKShareVideo()
fbVideo.videoURL = url
let content: FBSDKShareVideoContent = FBSDKShareVideoContent()
content.video = fbVideo
FBSDKShareDialog.showFromViewController(self, withContent: content, delegate: self)

我有一个参数委托错误：

Cannot convert value of type 'ShareViewController' to expected argument type 'FBSDKSharingDelegate!'

请注意，我在我的类ShareViewController中。

有没有其他方法可以在Facebook上分享视频？ 谢谢

Answer 1

方法showFromViewController:withContent:delegate:期望委托参数的类型为FBSDKSharingDelegate 。 您提供的是ShareViewController类型的值， ShareViewController不是FBSDKSharingDelegate ，这意味着所述视图控制器不符合该类型。 您需要使您的视图控制器符合FBSDKSharingDelegate类型。 举个例子：

class ShareViewController: UIViewController, FBSDKSharingDelegate {
    // code
}

或传入另一个符合FBSDKSharingDelegate类型的FBSDKSharingDelegate 。

Answer 2

您必须实现FBSDKSharingDelegate协议及其方法。

    class ViewController: UIViewController ,FBSDKSharingDelegate{

    //add following methods to the class:
func sharer(_ sharer: FBSDKSharing!, didCompleteWithResults results: [AnyHashable : Any]!) {
            print("Completed");
        }


        func sharer(_ sharer: FBSDKSharing!, didFailWithError error: Error!) {
            print("Failed with error : \(error.localizedDescription)");
        }

        func sharerDidCancel(_ sharer: FBSDKSharing!) {
            print("Cancelled")
        }

    }
