清除 WebView 缓存 xamarin IOS

Question

我需要在关闭 WebView 后清除缓存我使用来自的代码但它没有效果。已经明白 records.Count equals 0

如何正确设置？

var websiteDataTypes = new NSSet<NSString>(new []
{
    //Choose which ones you want to remove
    WKWebsiteDataType.Cookies,
    WKWebsiteDataType.DiskCache,
    WKWebsiteDataType.IndexedDBDatabases,
    WKWebsiteDataType.LocalStorage,
    WKWebsiteDataType.MemoryCache,
    WKWebsiteDataType.OfflineWebApplicationCache,
    WKWebsiteDataType.SessionStorage,
    WKWebsiteDataType.WebSQLDatabases
});

WKWebsiteDataStore.DefaultDataStore.FetchDataRecordsOfTypes (websiteDataTypes, (NSArray records) =>
{
    for (nuint i = 0; i < records.Count; i++) {
        var record = records.GetItem<WKWebsiteDataRecord> (i);

        WKWebsiteDataStore.DefaultDataStore.RemoveDataOfTypes (record.DataTypes, 
            new[] {record}, () => {Console.Write($"deleted: {record.DisplayName}");});
    }
});

通过以下代码解决了问题：

NSHttpCookieStorage CookieStorage = NSHttpCookieStorage.SharedStorage;

        foreach (var cookie in CookieStorage.Cookies)
            CookieStorage.DeleteCookie(cookie);
