iOS WKWebView不支持本地存储 [英] iOS WKWebView does not support local storage

问题描述

我正在构建一个简单的WKWebView应用程序，该应用程序可以加载用Construct(HTML5)编写的游戏.

I am building a simple WKWebView app that loads a game written in Construct (HTML5).

游戏存储在服务器上，当我在常规浏览器(移动和台式机)上玩游戏时，游戏本身存储在本地，高分也存储在本地.重新启动后，该游戏不需要重新下载，我可以看到以前的高分.

The game is stored on a server, when I play the game in a regular browser (both mobile and desktop) the game itself gets stored locally and also high-scores are stored locally. After relaunch the game does not require a re-download as well as I can see the previous high-score.

我不知道Construct用于存储本地数据的确切方式，但是当我在WKWebView中运行完全相同的游戏时，该游戏也不会存储在本地，也不会获得高分.

I dont know what exactly does Construct use to store local data, but when I run the exact same game in my WKWebView the game does not get stored locally nor do the high-scores.

我的Swift代码是这样的:

My Swift code is this:

import UIKit
import WebKit

class ViewController: UIViewController, WKUIDelegate, {
    var webView: WKWebView!

    override func loadView() {
        let webConfiguration = WKWebViewConfiguration()
        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.uiDelegate = self
        webView.navigationDelegate = self
        view = webView
    }
    override func viewDidLoad() {
        super.viewDidLoad()

        let htmlPath = Bundle.main.path(forResource: "game", ofType:"html")
        let url = URL(fileURLWithPath: htmlPath!)
        let request = URLRequest(url: url)
        webView.load(request)
    }
}

我的WKWebView显然缺少允许其存储脱机数据的某些功能或设置.

My WKWebView is apparently missing some feature or setting that allows it to store offline data.

推荐答案

您需要添加此

webConfiguration.websiteDataStore = WKWebsiteDataStore.default()

Apple文档没有明确说明，但我认为默认的WKWebsiteDataStore是持久的.

Apple documentation doesn't clearly state it but I think the default WKWebsiteDataStore is persistent.

在此处阅读有关WKWebsiteDataStore/本地存储的信息

此外，您还可以检查数据存储是否持久是否.

Further, you can also check whether the data store is persistent or not.
