我有一个问题,没有调用didReceiveData和didCompleteWithError.这是我的代码:

class LoginViewController: UIViewController, NSURLSessionDataDelegate, NSURLSessionDelegate, NSURLSessionTaskDelegate {
.
.
.
}

@IBAction func loginAction(sender: AnyObject) {

    var sessionConfiguration = NSURLSessionConfiguration.defaultSessionConfiguration()

    var session = NSURLSession(configuration: sessionConfiguration, delegate: self, delegateQueue:nil)

    let postParams = "email="+"rabcd@gmail.com&password="+"abcd"

    let url = NSURL(string:"http://myurl.com/api/v1/user/login")
    let request = NSMutableURLRequest(URL: url!)

    request.HTTPMethod = "POST"

    request.HTTPBody = postParams.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)

    let task = session.dataTaskWithRequest(request)


    task.resume()


}

这些是我实施的代表

func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveResponse response: NSURLResponse, completionHandler: (NSURLSessionResponseDisposition) -> Void) {

}

func URLSession(session: NSURLSession, dataTask: NSURLSessionDataTask, didReceiveData data: NSData) { …
