单个视图控制器中的多个WKwebkit视图不起作用

Question

我无法加载我的子视图。我将它们定义为弱WKWebKit插座。如果我确实执行view = tickerView或view = graphView，它可以工作，但只加载其中之一。我要同时加载两者。我该怎么办？

    override func loadView() {

        tickerView = WKWebView()
        tickerView.navigationDelegate = self
        self.view.addSubview(tickerView)


        graphView = WKWebView()
        graphView.navigationDelegate = self
        self.view.addSubview(graphView)

    }

import UIKit
import WebKit

let SCREEN_WIDTH : CGFloat = UIScreen.main.bounds.width
let SCREEN_HEIGHT : CGFloat = UIScreen.main.bounds.height

class ViewController: UIViewController,WKNavigationDelegate{
  override func viewDidLoad() {
    super.viewDidLoad()

    let webView1 = WKWebView()
    webView1.frame = CGRect(x: 0, y: 0, width: SCREEN_WIDTH, height: 200)
    webView1.load(URLRequest(url: URL(string: "https://www.google.com/")!))
    self.view.addSubview(webView1)
    webView1.navigationDelegate = self

    let webView2 = WKWebView()
    webView2.frame = CGRect(x: 0, y: 250,width: SCREEN_WIDTH,height: 200)
    webView2.load(URLRequest(url: URL(string: "https://www.youtube.com/")!))
    self.view.addSubview(webView2)
    webView2.navigationDelegate = self
  }
}
