WKWebView无法加载(NSViewController，OS X) [英] WKWebView Won't Load (NSViewController, OS X)

问题描述

我正在尝试构建一个简单的WKWebView应用程序，该应用程序将在WebView中显示Google.该应用程序运行正常；但是，在实现WKWebView之后，该应用将不再显示窗口.它只是在看不到NSView的情况下(在扩展坞中)启动应用程序.

I am trying to build a simple WKWebView application that will display Google in the WebView. The app works perfectly fine; however, upon implementing the WKWebView, the app no longer shows a window. It just simply launches the app (in the dock) with no NSView in sight.

ViewController.swift

import Cocoa
import WebKit

class ViewController: NSViewController {

    var webView: WKWebView?

    override func loadView() {
        self.webView = WKWebView()
        self.view = self.webView!

        let url = NSURL(string:"http://www.google.com/")
        let req = NSURLRequest(URL: url!)
        self.webView!.loadRequest(req)
    }

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

似乎没有更多的在线示例，或者GitHub上也没有任何项目.

There doesn't seem to be any further examples online, nor does there seem to be any projects on GitHub.

谢谢.我以前没有遇到过.

Thanks. I haven't come across this before.

推荐答案

我想Xcode设置背后有一些限制，那些隐藏的设置使您的WKWebView无法正常工作！
