Question

我的viewController中有一些代码

 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))
    }

但是我收到错误：＆＃39; ViewController.Type＆＃39;没有名为＆＃39; URL＆＃39;的成员。如果我将代码放在ViewDidLoad中，它适用于应用程序启动。

如何通过点击按钮运行代码？我尝试将@IBAction放在ViewDidLoad函数中，但这也不起作用：/

@IBOutlet var serverLabel: UILabel!

@IBAction func serverButton(sender: AnyObject) {


}


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


}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

}

}

您的所有代码都不在方法中，将其包装在方法中并在适当时调用该方法。

Swift：'ViewController.Type'没有名为'URL'的成员
