Swift:“ViewController.Type"没有名为“URL"的成员 [英] Swift: 'ViewController.Type' does not have a member named 'URL'

问题描述

我的 viewController 中有一些代码

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))
    }

但是我收到错误消息:ViewController.Type"没有名为URL"的成员.如果我将代码放在 ViewDidLoad 中，它可以在应用程序启动时运行.

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.

如何让代码在单击按钮时运行?我尝试将 @IBAction 放在 ViewDidLoad func 中，但这也不起作用:/

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 :/

推荐答案

你的代码都不在方法中，把它包装在一个方法中，并在适当的时候调用这个方法.

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