Question

我有一个问题。

当我print("Video URL: \(self.videoUrl.description)")时，我在输出中得到了这个：

Video URL: file:///var/mobile/Containers/Data/Application/92BDA035-131C-4FD2-A176-25F77C1D295B/Documents/video.mp4

我使用它将文件上传到服务器：

func uploadVideo(){
        let currentUploads = PFObject(className: "myClassOne")
        currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
            if error == nil{
                //**Success saving, now save video.**//

                currentUploads["userFile"] = try! PFFile(name: "video.mp4", contentsAtPath: self.videoUrl.description)
                currentUploads.saveInBackgroundWithBlock({ (success: Bool, error: NSError?) -> Void in
                    if error == nil{
                        // Take user home
                        print("Successfully uploaded")
                        })
                    }
                    else{
                        print(error, terminator: "")
                    }
                })
            }
            else{
                print(error, terminator: "")
            }
        })
    }

我收到此错误：

致命错误：＆＃39;尝试！＆＃39;表达式意外地引发了错误：错误 Domain = NSCocoaErrorDomain Code = 4＆＃34;无法在路径上创建PFFile ＆＃39;文件：///var/mobile/Containers/Data/Application/92BDA035-131C-4FD2-A176-25F77C1D295B/Documents/video.mp4' ;: 文件不存在。＆＃34; UserInfo = {NSLocalizedDescription =失败在路径上创建PFFile ＆＃39;文件：///var/mobile/Containers/Data/Application/92BDA035-131C-4FD2-A176-25F77C1D295B/Documents/video.mp4' ;: 文件不存在。}：file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-703.0.18.1/src/swift/stdlib/public/core/ErrorType.swift，第54行

有什么问题？当我从println成功获取网址时，为什么会出现“文件不存在”？有什么想法/建议吗？

NSURL错误 - 文件不存在
