ios - 对成员 'dataTask(with:completionHandler:)' 的模糊引用

Question

您好，我刚刚完成了到 Swift 3.0 的转换，并且返回了很多错误。第一个是:

Ambiguous reference to member 'dataTask(with:completionHandler:)'

找到这个候选人

有没有人有解决办法？

给出这个的代码是:

let task = session.dataTask(with: request) {
        (
        data, response, error) in

        guard let _:Data = data, let _:URLResponse = response  , error == nil else {
            print(data)
            print("error")
            return
        }

        _ = NSString(data: data!, encoding: String.Encoding.utf8)

        //print(dataString)
    }

Answer 1

尝试这样的事情

 guard let requestUrl = URL(string:yourUrlString) else { return }
 let request = URLRequest(url:requestUrl)
 let task = session.dataTask(with: request) {
    (data, response, error) in
    if error == nil {
        //JSONSerialization
    }
 }
