Question

这是我要将数据发布到我的网站页面的代码，但我得到了错误：

objc [17272]：类PLBuildVersion在两者中实现 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices （0x1193af998）和 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices （0x1191d4d38）。将使用两者之一。哪一个未定义。错误 /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit_Sim/VectorKit-1230.31.8.23.3/GeoGL/GeoGL/GLCoreContext.cpp 1763：InfoLog SolidRibbonShader：错误 /BuildRoot/Library/Caches/com.apple.xbs/Sources/VectorKit_Sim/VectorKit-1230.31.8.23.3/GeoGL/GeoGL/GLCoreContext.cpp 1764：警告：未读取顶点着色器'v_gradient'的输出片段着色器

func senddata(_ submit:String, username:String,password:String, email:String, jobtype:String, pay:String){


        let myUrl = URL(string: "http://localhost/halloffame/php/senddata.php");
        let request = NSMutableURLRequest(url:myUrl!);
        request.httpMethod = "POST";

        let postString = "submit=\(submit)&jobtype=\(jobtype)&pay=\(pay)";

        request.httpBody = postString.data(using: String.Encoding.utf8);

        let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data:Data?, response:URLResponse?, error:NSError?) -> Void in
            DispatchQueue.main.async
            {

                // if there is an error throw an alert message
                if(error != nil)
                {
                    //Display an alert message
                    let myAlert = UIAlertController(title: "Alert", message: "something wrong", preferredStyle: UIAlertControllerStyle.alert);
                    let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler:nil)
                    myAlert.addAction(okAction);
                    self.present(myAlert, animated: true, completion: nil)
                    return
                }
                // get feedback from the website
                do {
                    let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
                    if let parseJSON = json {
                        // if status is 200
                        let status = parseJSON["status"] as? String
                        if(status! == "200")
                        {
                            // show the result of the data
                            let status = parseJSON["status"]
                        }else {
                            // display an alert message
                            let myAlert = UIAlertController(title: "Alert", message: status, preferredStyle: UIAlertControllerStyle.alert);
                            let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler:nil)
                            myAlert.addAction(okAction);
                            self.present(myAlert, animated: true, completion: nil)
                        }

                    } // end of parseJSON
                } catch
                {
                    print(error)
                }
            }// dispatch
            } as! (Data?, URLResponse?, Error?) -> Void).resume() // nsurlsession

源代码是代码的最后一行，我试图将该行删除为！ (Data?, URLResponse?, Error?) -> Void)但是XCODE给了我错误并建议再次添加它。如果我用代码构建一个模拟器，它显示没有问题，直到我调用该函数，然后它冻结并给了我这个错误。这不会发生在swift 2中，但只有在升级后才会发生。

Answer 1

我在iPhone应用程序中遇到了类似的错误。重置iOS模拟器为我修复了它。模拟器 - ＆gt;重置内容和设置。

Answer 2

我找到了解决方案：

in

   let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data:Data?, response:URLResponse?, error:NSError?) -> Void in
            DispatchQueue.main.async

我将其改为

let task = URLSession.shared.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
            DispatchQueue.main.async

然后我删除底部的数据，响应，错误从这个

 } as! (Data?, URLResponse?, Error?) -> Void).resume() // nsurlsession

进入这个

 }).resume() // nsurlsession

我得到了这个错误objc [17272]：类PLBuildVersion在两者中实现
