如何上传录制的音频文件进行解析？

Question

在这里发布我的代码,被截取到下面.

根据上面的代码,我正在创建一个sound.caf在已知文件路径位置调用的音频文件soundfileURL.

我的问题是如何将此文件上传到Parse？如何从路径中获取代码中的文件对象soundfileURL.

我在下面的尝试显然需要工作.我没有运行它,因为我不知道如何转换sound.caf为PFFile并上传到Parse.

func addNamestoParse(obj: Music) {
    println("Doing Parse Stuff now")
    self.showActivityIndicatory(true)

    var className = PFObject(className: "musicrecording")
    className.setObject(obj.name, forKey: "nameofmusic")
    className.setObject(obj.createdOn, forKey: "datcreated")

如何转换SOUND.CAF文件来支持这里并上传游戏？

    className.saveInBackgroundWithBlock {
        (success: Bool, error: NSError?) -> Void in

        if success == true {



        } else {

            println(error)

        }
    }

}

感谢David Jirman的Objective-C等价能够推断出Swift Equivalent.下面是代码.

func addNamestoParse(obj: Name) {
    println("Doing Parse Stuff now")

    var className = PFObject(className: "namerecordings")
    className.setObject(obj.name, forKey: "babyname")
    className.setObject(obj.nameSubmitter, forKey: "submittedby")
    className.saveInBackgroundWithBlock {
        (success: Bool, error: NSError?) -> Void in

        if success == true {
            let audioFile = PFFile(name: "mysound.caf", data: NSData(contentsOfURL: self.soundFileURL)!)
            className["audioFile"] = audioFile

            className.saveInBackgroundWithBlock{(success: Bool, error: NSError?) -> Void in

                if success == false {
                    println("error in uploading audio file")
                } else {
                    println("posted successfully")

                }
            }

        } else {

            println(error)

        }
    }

}

在https://www.youtube.com/watch?v=4qj1piMAPE0这个很棒的教程之后,我的解决方案是在Swift中:

    let path = getCacheDirectory().stringByAppendingPathComponent(fileName)
    let filePath = NSURL(fileURLWithPath: path)

    var dataToUpload : NSData = NSData(contentsOfURL: filePath!)!

    let soundFile = PFFile(name: fileName, data: dataToUpload)
    var userSound = PFObject(className:"upload")
    userSound["name"] = "Sara"
    userSound["sound"] = soundFile
    userSound.saveInBackground()

其中getCacheDirectory()是本教程中使用的函数
