WKWebView中的主页按钮，Swift

Question

I have a WkWebView that load an url (example.com) with 2 button: back and home.

Code for back button is

func goBack(_ sender: Any) {
    if webView.canGoBack{
        webView.goBack()
    }
}

and works fine.

Code for home button is

func goHome(_ sender: Any) {
    let myURL = URL(string: "example.com")
    let myRequest = URLRequest(url: myURL!)
    webView.load(myRequest)
}

but this works also if I'm already in example.com.

How can I make a check for reload example.com only if I'm not in example.com?

Answer 1

You simply need to check against the web view's current URL. The following would suffice:

if webView.url != myURL {
    let myRequest = URLRequest(url: myURL!)
    webView.load(myRequest)
}

Though I would recommend adding an appropriate scheme and path to your URL else this will return false. eg URL(string: "https://example.com/") .
