How to get the status code from HTTP Get in swift?

Question

I have try the following code to implement HTTP Get in IOS Swift.

NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler: {(response: NSURLResponse!, data: NSData!,error: NSError!) -> Void in

            var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
            println("response = \(response)")
        })

It success and show the following response:

response = <NSHTTPURLResponse: 0x155xxxxx> { URL: http://xxx.xx.xxx.xxx:38080/getid/user-wiced1 } 
{ status code: 200, headers {
    "Content-Length" = 111;
    "Content-Type" = "application/json; charset=UTF-8";
    Date = "Thu, 08 Jan 2015 07:31:21 GMT";
    Server = "spray-can/1.3.2-20140909";
} }

How to get the status code from NSURLResponse ?

Thanks in advance.

Solution

NSURLResponse do not have status code, but NSHTTPURLResponse does. So cast it:

let httpResponse = response as NSHTTPURLResponse
httpResponse.statusCode

Is it mean change the type of response to the NSHTTPURLResponse , and get the statusCode?

You do not "change" the type by casting. As your print show the type is already NSHTTPURLResponse, but your are using it superclass interface NSURLResponse. You need to change interface by casting to access status code.
