得到“线程1:EXC_BAD_ACCESS"；错误? [英] Getting "Thread 1:EXC_BAD_ACCESS" error?

问题描述

我正在使用WKWebView和Swift语言创建一个简单的Web查看器.这是我的代码.

I am creating a simple web viewer using WKWebView and the Swift language. Here is my code.

import Cocoa
import WebKit

@NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate {

    @IBOutlet var containerView : NSView! = nil
    @IBOutlet weak var window: NSWindow!


    func applicationDidFinishLaunching(aNotification: NSNotification) {
        // Insert code here to initialize your application
        var webView: WKWebView

        webView = WKWebView() //Thread 1:EXC_BAD_ACCESS (code=1,address=0x20)
        var url = NSURL(string:"http://www.google.com/")
        var req = NSURLRequest(URL: url!)
        webView.loadRequest(req)
    }

    func applicationWillTerminate(aNotification: NSNotification) {
        // Insert code here to tear down your application
    }

}

当我尝试运行应用程序时，在webView = WKWebView()行上出现"Thread 1:EXC_BAD_ACCESS"错误.我该如何解决?

I'm now getting a "Thread 1:EXC_BAD_ACCESS" error on the webView = WKWebView() line when I try to run the application. How can I fix this?

推荐答案

每当尝试使用全新的最小类作为委托时，都会出现此错误.例如:

I get this error whenever I try to use a brand new minimal class as a delegate. For example:

class MyDelegate: NSObject, UIWebViewDelegate { /* ... */ }

class MyDelegate: NSObject, UIWebViewDelegate { /* ... */ }

当我尝试使用默认的ViewController作为委托时，不会发生这种情况.例如:

This does not happen when I try to use the default ViewController as a delegate. For example:

class ViewController: UIViewController, UIWebViewDelegate { /* ... */ }

class ViewController: UIViewController, UIWebViewDelegate { /* ... */ }

我建议您使用ViewController作为委托，直到我们深入到此为止.

I would suggest using the ViewController as a delegate until we get to the bottom of this.
