Swift: 'ViewController.Type' does not have

问题:

I have some code in my viewController

 var URL: NSURL = NSURL(string: "http://someurl.com")!
 var request : NSMutableURLRequest = NSMutableURLRequest(URL:URL)

 request.HTTPMethod = "POST"

 var bodyData = "data=something"


 NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue())
    {
        (response, data, error) in
        println(NSString(data: data, encoding: NSUTF8StringEncoding))
    }

However I get the error: 'ViewController.Type' does not have a member named 'URL'. If I put the code in the ViewDidLoad it works on app launch.

How do I get the code to run on the click of a button? I tried putting the @IBAction in the ViewDidLoad func but that doesnt work either :/

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

None of your code is in a method, wrap it up in a method and call the method when appropriate.
