ios - 将字符串转换为 plist - swift

Question

看来我可能是唯一一个尝试这样做的人，或者说这很简单，除了我之外每个人都已经知道怎么做了!

网站请求返回一个 plist 响应，响应以字符串形式接收。然后如何将该 plist“字符串”放入字典中？

let url = NSURL(string: "http://...")
let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 2.0)
request.HTTPMethod = "POST"

let boundaryConstant = "----------V2ymHFg03esomerasdfsalfkjlksjdfy"
let contentType = "mulutipart/form-data; boundary=" + boundaryConstant
NSURLProtocol.setProperty(contentType, forKey: "Content-Type", inRequest: request)
var dataString = ""
let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
request.HTTPBody = requestBodyData

var response: NSURLResponse? = nil
var error: NSError? = nil
let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)

let results = NSString(data: reply!, encoding: NSUTF8StringEncoding)

results 是一个 plist 字符串，带有 xml 头和 plist 结构后的数据。如果我使用

，plist 返回效果很好

NSDictionary(contentsOfURL: NSURL(string: path)!)!

但是，我是在发布，而不是“获取”，所以据我所知我不能使用 NSURL 路径。

提前致谢!

NSPropertyListSerialization 是你的 friend ，只要你真正得到 plist 数据:

if let plistData = results.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true) {
    var format = NSPropertyListFormat.XMLFormat_v1_0
    let options = NSPropertyListMutabilityOptions.Immutable
    if let dict = NSPropertyListSerialization.propertyListWithData(plistData, 
                                      options: NSPropertyListReadOptions(options.rawValue),
                                       format: &format, 
                                        error: nil) as? NSDictionary {
        println(dict)
    }
}
