¿Cómo eliminar el caché en WKWebview?

Question

¿ WKWebview trabajó con WKWebview e intentó borrar el caché? Si es así, ¿cómo hacerlo? algun ejemplo

PS: Normal NSURLCache no funciona.

Answer 1

Algo similar para iOS 9.0 y versiones posteriores:

let store: WKWebsiteDataStore = WKWebsiteDataStore.default()
let dataTypes: Set<String> = WKWebsiteDataStore.allWebsiteDataTypes()
store.fetchDataRecords(ofTypes: dataTypes, completionHandler: { (records: [WKWebsiteDataRecord]) in
  store.removeData(ofTypes: dataTypes, for: records, completionHandler: {
    // do your thing here
  })
})

Answer 2

En iOS 9

//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
                        WKWebsiteDataTypeDiskCache,
                        //WKWebsiteDataTypeOfflineWebApplicationCache,
                        WKWebsiteDataTypeMemoryCache,
                        //WKWebsiteDataTypeLocalStorage,
                        //WKWebsiteDataTypeCookies,
                        //WKWebsiteDataTypeSessionStorage,
                        //WKWebsiteDataTypeIndexedDBDatabases,
                        //WKWebsiteDataTypeWebSQLDatabases,
                        //WKWebsiteDataTypeFetchCache, //(iOS 11.3, *)
                        //WKWebsiteDataTypeServiceWorkerRegistrations, //(iOS 11.3, *)
                        ]];
//// All kinds of data
//NSSet *websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
//// Date from
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
//// Execute
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
   // Done
}];

Esto funciona para mi

 if #available(iOS 9.0, *) {
            let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
            let date = NSDate(timeIntervalSince1970: 0)
            WKWebsiteDataStore.defaultDataStore().removeDataOfTypes(websiteDataTypes as! Set<String>, modifiedSince: date, completionHandler:{ })
        }
        else
        {
          NSURLCache.sharedURLCache().removeAllCachedResponses()
        }

Answer 4

Me toma unas horas, ¡pero esto me funciona! Después de loadRequest, hago una recargaFromOrigin! ¡Así que fuerzo el caché vacío! [WKWebView loadRequest: request]; [WKWebView reloadFromOrigin];

Answer 5

No puede eliminar cachés solo con NSURLCache. Después de mucho cortar e intentar, pude borrar los cachés siguiendo estos pasos (a partir de iOS 8.1.1):

1. Use NSURLCache para eliminar cachés de la misma manera que solía hacer en UIWebView. Si usa WKProccessPool, reinícielo.
2. Eliminar el directorio de Caches en la Library .
3. Borrar todos los WKWebViews

La próxima vez que cree WKWebView, se borrarán los cachés.

Answer 6

Pude resolver este problema haciendo que mi WKWebView evalúe window.location.reload. Tengo un reconocedor de gestos de toques en la vista web y cada vez que detecta un doble toque con 2 toques, ejecuto lo siguiente:

webView.evaluateJavaScript("window.location.reload(true)", completionHandler: nil);

Espero que esto ayude.

Swift 3.x versión de la publicación de @ Esqarrouth

func clearCache() {
    if #available(iOS 9.0, *) {
        let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
        let date = NSDate(timeIntervalSince1970: 0)
        WKWebsiteDataStore.default().removeData(ofTypes: websiteDataTypes as! Set<String>, modifiedSince: date as Date, completionHandler:{ })
    } else {
        var libraryPath = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.libraryDirectory, FileManager.SearchPathDomainMask.userDomainMask, false).first!
        libraryPath += "/Cookies"

        do {
            try FileManager.default.removeItem(atPath: libraryPath)
        } catch {
            print("error")
        }
        URLCache.shared.removeAllCachedResponses()

Versión rápida:

if #available(iOS 9.0, *) {
  let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
  let date = NSDate(timeIntervalSince1970: 0)
  WKWebsiteDataStore.defaultDataStore().removeDataOfTypes(websiteDataTypes as! Set<String>, modifiedSince: date, completionHandler:{ })
} else {
    var libraryPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.LibraryDirectory, NSSearchPathDomainMask.UserDomainMask, false).first!
    libraryPath += "/Cookies"

    do {
      try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
    } catch {
      print("error")
    }
    NSURLCache.sharedURLCache().removeAllCachedResponses()
}

Versión Swift3:

   if #available(iOS 9.0, *)
    {
        let websiteDataTypes = NSSet(array: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache])
        let date = NSDate(timeIntervalSince1970: 0)

        WKWebsiteDataStore.default().removeData(ofTypes: websiteDataTypes as! Set<String>, modifiedSince: date as Date, completionHandler:{ })
    }
    else
    {
        var libraryPath = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.libraryDirectory, FileManager.SearchPathDomainMask.userDomainMask, false).first!
        libraryPath += "/Cookies"

        do {

        } catch {
            print("error")
