Swift - Webview在实现Javascript后通过导航栏覆盖

Question

我正在使用swift在我的iOS应用程序中实现JavaScript功能，并且它有效。但Web视图大小由导航栏覆盖。在我实现Javascript之前，Web视图大小是正确的。如何解决？

我对此功能的参考：https://kinderas.com/technology/2014/6/15/wkwebview-and-javascript-in-ios-8-using-swift

@IBOutlet var containerView: UIView!

var availabilityWebview: WKWebView?
override func loadView() {
    super.loadView()

    let contentController = WKUserContentController();
    let userScript = WKUserScript(
        source: "redHeader()",
        injectionTime: WKUserScriptInjectionTime.atDocumentEnd,
        forMainFrameOnly: true
    )
    contentController.addUserScript(userScript)
    contentController.add(
        self,
        name: "callbackHandler"
    )

    let config = WKWebViewConfiguration()
    config.userContentController = contentController

    //something wrong here
    self.availabilityWebview = WKWebView(
        frame: self.containerView.bounds,
        configuration: config
    )
    self.view = self.availabilityWebview!
}

覆盖func viewWillAppear

let url = URL(string: "http://ec2-52-221-231-3.ap-southeast-1.compute.amazonaws.com/gv/available-schedule_3.php?id=\(crewID)")
self.availabilityWebview?.load(URLRequest(url:url!))

我通过在viewDidLoad

中添加此代码解决了我的问题

self.edgesForExtendedLayout = []
