使用Swift

Question

我正在使用框架RebekkaTouch将文件从我的Swift应用程序上传到FTP服务器，就像：

if let URL = NSBundle.mainBundle().URLForResource("myFile", withExtension: "txt") {
    let path = "myFile.txt"
    session.upload(URL, path: path) {
        (result, error) -> Void in
        print("result:\n\(result), error: \(error)\n\n")
    }
}

这适用于我通过Xcode手动上传的文件。但我似乎无法找到我在Documents目录上本地下载和存储的文件的文件路径。

说，我知道我有这个文件：/private/var/mobile/Containers/Data/Application/3D92EA55-01E0/Documents/SomeFile.txt

我知道它就在那里因为我在循环NSFileManager.defaultManager()之后得到了路径但是我无法将其转换为NSURL所以我可以上传它。

有什么想法吗？

//// UPDATE

这就是死亡的地方：

let file = "myFile.txt"
if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
    //path will be stored here
    let sPath = dir.stringByAppendingPathComponent(file);
    print(sPath) //  printing the file path

    let url: NSURL = NSURL(string: sPath)!

    let destinationFile = "myFile.txt"
    FTPSession.upload(url, path: destinationFile) { // <-- Dies here
        (result, error) -> Void in
        print("- Result:\n\(result), error: \(error)\n\n")
    }
}

以下是示例

  

此代码在Swift 2.0上进行了全面测试

 let file = "SomeFile.txt"
        if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
           //path will be stored here
            let sPath = dir.stringByAppendingPathComponent(file);

      print(sPath) //  printing the file path
        }

比你可以执行上传

  

编辑关于将字符串转换为NSURL的评论

let URL: NSURL = NSURL(string: stringofURL)! //replace stringofURL to sPath

  

更新了您的代码

let file = "myFile.txt"
if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {
    //path will be stored here
    let sPath = dir.stringByAppendingPathComponent(file);
    print(sPath) //  printing the file path

    let url: NSURL = NSURL(string: sPath)!

    let destinationFile = "myFile.txt"
    session.upload(url, path: destinationFile) { // here was the error it should be session not FTPsession
        (result, error) -> Void in
        print("- Result:\n\(result), error: \(error)\n\n")
    }
}
