Ios 从服务器Objective C或Swift下载文件

如何将音频文件从我的服务器下载到用户的手机，以便在应用程序中使用？当我转到网站链接时，JSON代码如下所示

        let urlPath = "http://www.domain.us/"

        let url = NSURL(string: urlPath)

        let session = NSURLSession.sharedSession()

        let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in

            if error != nil {
                println(error)
            } else {
                let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
                println(jsonResult)
            }

        })

        task.resume()
    }

[{“name”：“Lets Party”，“path”：“http:\/\/domain.us\/\/\/audios\/\/Lets Party.wav”}，
{“名称”：“让你知道”，“路径”：“http:\/\/domain.us\/\/\/audios\/\/Let You Know.wav”}，
{“name”：“OMG”，“path”：“http:\/\/domain.us\/\/\/audios\/\/OMG.wav”}]

我尝试获取JSON并在Swift中进行转换，但这使我的应用程序崩溃。但是当我把一个博客放在JSON上时，它工作得非常完美，没有崩溃。我怎样才能在Swift或Objective-C中做到这一点

        let urlPath = "http://www.domain.us/"

        let url = NSURL(string: urlPath)

        let session = NSURLSession.sharedSession()

        let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in

            if error != nil {
                println(error)
            } else {
                let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
                println(jsonResult)
            }

        })

        task.resume()
    }

编辑：我现在收到一条错误消息

        let urlPath = "http://www.domain.us/"

        let url = NSURL(string: urlPath)

        let session = NSURLSession.sharedSession()

        let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in

            if error != nil {
                println(error)
            } else {
                let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
                println(jsonResult)
            }

        })

        task.resume()
    }

当前代码：

        let urlPath = "http://www.domain.us/"

        let url = NSURL(string: urlPath)

        let session = NSURLSession.sharedSession()

        let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in

            if error != nil {
                println(error)
            } else {
                let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
                println(jsonResult)
            }

        })

        task.resume()
    }

错误消息：

        let urlPath = "http://www.domain.us/"

        let url = NSURL(string: urlPath)

        let session = NSURLSession.sharedSession()

        let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in

            if error != nil {
                println(error)
            } else {
                let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
                println(jsonResult)
            }

        })

        task.resume()
    }

您需要显示您的代码。这也是转义的JSON，因此如果您使用NSJSONSerialization解析它，它将无法工作。在我看来，这是一个传输错误-您尝试过调试请求吗？我的猜测仍然是服务器正在反馈转义（无效）json，它不应该这样做。对不起，我是一个初学者，所以我不太明白你刚才说的话。lol。我应该怎么做？你为什么要使用旧的Xcode？Xcode 6.1是最新版本。你应该从AppStorey下载是的，只是在学习swift，我完全忘了升级swift，现在将升级并测试代码，我会让你知道的。谢谢。非常感谢！你不知道你帮了我多少忙！你能改变答案中的网址吗？哈哈，再次感谢！
