分享视频到Facebook

Question

我正在编写一个简单的测试应用程序,用于将视频从iOS上传到Facebook.

我发现很难在线找到关于如何使用Swift执行此操作的示例/教程,因为FacebookSDK的所有文档都在Objective-C中.

到目前为止我有这个在我的UI上放置一个共享按钮,但它看起来已禁用,从我读到的这是因为没有内容设置,但我看不出这是怎么可能的.

    let video_content : FBSDKShareVideoContent = FBSDKShareVideoContent()

    video_content.video = FBSDKShareVideo(videoURL: getVideoURL())

    let button : FBSDKShareButton = FBSDKShareButton()
    button.shareContent = video_content

    button.frame = CGRectMake((UIScreen.mainScreen().bounds.width - 100) * 0.5, 50, 100, 25)
    self.view.addSubview(button)

我的getVideoURL()函数返回一个NSURL,它肯定包含视频的url(我已经将它打印到控制台并检查它指向我之前存储在文件夹中的视频).

我查看了社交框架,遗憾的是我无法使用它,因为它似乎只用于分享照片而无法分享视频.

我正在使用最新版本的Xcode,Swift和Facebook SDK.

转换成swift 3和4: - 试试这个

func uploadVideoOnFacebook() {
        var pathURL: URL
        var videoData: Data
        pathURL = URL(string: "Your video url string")!
        do {
            videoData = try Data(contentsOf: URL(string: "Your video url string")!)
            print(videoData)
            var strDesc : String
            strDesc = ""
            let videoObject: [String : Any] = ["title": "application Name", "description": strDesc, pathURL.absoluteString: videoData]
            let uploadRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me/videos", parameters: videoObject, httpMethod: "POST")
            self.view!.isUserInteractionEnabled = false
            uploadRequest.start(completionHandler: {(connection: FBSDKGraphRequestConnection, result: AnyObject, error: NSError) -> Void in
                if error == error {
                    NSLog("Error")

                }
                else {
                    NSLog("Success")
                }
            } as! FBSDKGraphRequestHandler)
        } catch {
            print(error)
        }

    }

@愤怒的鸭子

尝试这个代码它会工作

func uploadVideoOnFacebook() {
    var pathURL: NSURL
    var videoData: NSData
    pathURL = NSURL(string: self.strUploadVideoURL)!
    videoData = NSData.dataWithContentsOfURL(NSURL(string: self.strUploadVideoURL)!)
    NSString * strDesc
    strDesc = txtCaption.text!
    var videoObject: [NSObject : AnyObject] = ["title": "application Name", "description": strDesc, pathURL.absoluteString(): videoData]
    var uploadRequest: FBRequest = FBRequest(graphPath: "me/videos", parameters: videoObject, HTTPMethod: "POST")
    self.view!.userInteractionEnabled = false
    uploadRequest.startWithCompletionHandler({(connection: FBRequestConnection, result: AnyObject, error: NSError) -> Void in
        if !error {
            NSLog("Success")
        }
        else {
            NSLog("Error")
        }
    })
}
