我正在使用新版Swift为我的Soap服务做更新，但我不知道如何解决这些错误：
class ViewController: UIViewController, UITextFieldDelegate, NSURLConnectionDelegate, NSXMLParserDelegate {
var mutableData: NSMutableData = NSMutableData.alloc()
var currentElementName: NSString = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
var soapMessage = "<?xml version='1.0' encoding='UTF-8'?> ...</SOAP-ENV:Envelope>"
var urlString = "https://..."
var url = NSURL(string: urlString)
var theRequest = NSMutableURLRequest(URL: url!)
var msgLength = String(count(soapMessage))
theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
theRequest.addValue(msgLength, forHTTPHeaderField: "Content-Length")
theRequest.addValue("urn:ResponseAction", forHTTPHeaderField: "SOAPAction")
theRequest.HTTPMethod = "POST"
theRequest.HTTPBody = soapMessage.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
var connection = NSURLConnection(request: theRequest, delegate: self, startImmediately: true)
connection?.start()
if(connection == true) {
var mutableData : Void = NSMutableData.initialize()
}
}
func connection(connection: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
mutableData.length = 0;
}
func connection(connection: NSURLConnection!, didReceiveData data: NSData!) {
mutableData.appendData(data)
}
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
{
challenge.sender.useCredential(NSURLCredential(forTrust: challenge.protectionSpace.serverTrust), forAuthenticationChallenge: challenge)
challenge.sender.continueWithoutCredentialForAuthenticationChallenge(challenge)
}
func connectionDidFinishLoading(connection: NSURLConnection!) {
let xmlParser = NSXMLParser(data: mutableData)
xmlParser.delegate = self
xmlParser.parse()
xmlParser.shouldResolveExternalEntities = true
}
func parser(parser: NSXMLParser,
didStartElement elementName: String,
namespaceURI: String?,
qualifiedName qName: String?,
attributes attributeDict: [NSObject : AnyObject]) {
currentElementName = elementName
}
func parser(parser: NSXMLParser, foundCharacters string: String) {
if currentElementName == "LoginReturn" {
print(string)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
错误：

我对代码进行了更正：
import UIKit
class ViewController: UIViewController, UITextFieldDelegate, NSURLConnectionDelegate, NSXMLParserDelegate {
var mutableData: NSMutableData = NSMutableData()
var currentElementName: NSString = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let soapMessage = "..."
let urlString = "https://..."
let url = NSURL(string: urlString)
let theRequest = NSMutableURLRequest(URL: url!)
let msgLength = String(soapMessage.characters.count)
theRequest.addValue("text/xml; charset=utf-8", forHTTPHeaderField: "Content-Type")
theRequest.addValue(msgLength, forHTTPHeaderField: "Content-Length")
theRequest.addValue("urn:ResponseAction", forHTTPHeaderField: "SOAPAction")
theRequest.HTTPMethod = "POST"
theRequest.HTTPBody = soapMessage.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
let connection = NSURLConnection(request: theRequest, delegate: self, startImmediately: true)
connection?.start()
if(connection == true) {
let mutableData : Void = NSMutableData.initialize()
}
}
func connection(connection: NSURLConnection!, didReceiveResponse response: NSURLResponse!) {
mutableData.length = 0;
}
func connection(connection: NSURLConnection!, didReceiveData data: NSData!) {
mutableData.appendData(data)
}
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge)
{
challenge.sender!.useCredential(NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!), forAuthenticationChallenge: challenge)
challenge.sender!.continueWithoutCredentialForAuthenticationChallenge(challenge)
}
func connectionDidFinishLoading(connection: NSURLConnection!) {
let xmlParser = NSXMLParser(data: mutableData)
xmlParser.delegate = self
xmlParser.parse()
xmlParser.shouldResolveExternalEntities = true
}
func parser(parser: NSXMLParser,
didEndElement elementName: String,
namespaceURI: String?,
qualifiedName qName: String?,
attributes attributeDict: [NSObject : AnyObject]) {
currentElementName = elementName
}
func parser(parser: NSXMLParser, foundCharacters string: String) {
if currentElementName == "LoginReturn" {
print(string)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
但是，当我运行我的应用程序时，我什么都没得到
