Question

我在swift工作，最初收到警告＆＃34;＆＃39; stringByAddingPercentEscapesUsingEncoding＆＃39;被弃用...＆＃34;所以我改变了我的代码

    let url = NSURL(string: (urlString as NSString).stringByAddingPercentEscapesUsingEncoding(NSASCIIStringEncoding)!)

到

    var url = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

但现在我收到了错误＆＃34;无法转换类型＆＃39; String＆＃39;预期参数类型＆＃39; NSURL＆＃39;。

    let urlRequest = NSURLRequest(URL: url!)

我目前的代码：

    private func handleTextFieldInterfaces(){
    autocompleteTextField.onTextChange = {[weak self] text in
        if !text.isEmpty{
            if self!.connection != nil{
                self!.connection!.cancel()
                self!.connection = nil
            }
            let urlString = "\(self!.baseURLString)?key=\(self!.googleMapsApiKey)&input=\(text)"
            //let url = NSURL(string: (urlString as NSString).stringByAddingPercentEscapesUsingEncoding(NSASCIIStringEncoding)!)

           var url = urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

            if url != nil{
                let urlRequest = NSURLRequest(URL: url!) //Error on this line
                self!.connection = NSURLConnection(request: urlRequest, delegate: self)
            }
        }
    }


}

尝试将其投射到NSURL，看看它是否有效

var url = NSURL(urlString.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet()))

无法转换类型＆＃39; String＆＃39;的值到＆＃39; NSURL＆＃39;
