Question

我正在尝试在Swift中创建一个WebView，并在class AppDelegate: UIResponder, UIApplicationDelegate {行上获取错误代码“Thread 1：signal SIGABRT”

我的代码如下（变量“theURL”确实有一个真实的URL）：

    import UIKit

class ViewController: UIViewController {


    @IBOutlet var Webview: UIWebView!

    var theURL = "URL"

    func loadWebPage() {
        let theRequestURL = NSURL (string: theURL)
        let theRequest = NSURLRequest(URL: theRequestURL!)
        Webview.loadRequest(theRequest)

    }

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



    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

提前致谢！

Answer 1

您必须将此页面链接到Main.Storyboard。您可以使用Main.Storyboard中的Web View。

Answer 2

其中一个原因 -

在打开它之前检查有效的url对象

if let theRequestURL = NSURL (string: theURL) {
    let theRequest = NSURLRequest(URL: theRequestURL!)
    Webview.loadRequest(theRequest)
}

或者从故事板中未正确连接Webview，也未在代码中初始化

Answer 3

我理解这个问题是从一段时间以来我只是遇到了完全相同的问题，我通过检查main.storyboard文件中的插座连接解决了这个问题。我从代码中删除了一个插座，但没有从main.storyboard删除。点击所有视图并检查他们的插座连接。

我希望这可以解决问题：）

while True:
        if args.connect:
            server_socket.send(bytes(" success ".join([args.interface, args.device]), 'utf-8'))
            recived_response=server_socket.recv(1048)
            d_rec= recived_response.decode("utf-8")
            msg_array=d_rec.split(" ")
            if 'connect' in msg_array:
                connect(relayboards.get(devices[args.device][args.interface].get("board")) ,int(PORT))
                digital_command(args.device, args.interface, "connect")
                print("ready to connect...%s" % d_rec)
                print("~~CONNECTED~~")
                #server_socket.close()
                break
            else:
                continue
                #print("oops")

        elif args.disconnect:
            connect(relayboards.get(devices[args.device][args.interface].get("board")) ,int(PORT))
            server_socket.send(bytes(" failure ".join([args.interface, args.device]), 'utf-8'))
            if  server_socket.recv(30)== b'disconnect':
                digital_command(args.device, args.interface, "disconnect")
                print("~~DISCONNECTED~~")
                #server_socket.close()
                break
            else:
                print("the device was not connected at the first place")
                #server_socket.close()
                break
