¿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.

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()
}
}

Swift 3. Versión.
Para la versión anterior Swift

import Foundation
import WebKit
func removeWebData() {
if #available(iOS 9.0, *) {
let websiteDataTypes = WKWebsiteDataStore.allWebsiteDataTypes()
let date = NSDate(timeIntervalSince1970: 0)
WKWebsiteDataStore.default().removeData(ofTypes: websiteDataTypes, modifiedSince: date as Date, completionHandler: {
#if DEBUG
print("remove all data in iOS9 later")
#endif
})
}else {
// Remove the basic cache.
URLCache.shared.removeAllCachedResponses()
// Delete system cookie store in the app
let storage = HTTPCookieStorage.shared
if let cookies = storage.cookies {
for cookie in cookies {
storage.deleteCookie(cookie)
}
}
do {
// folder 를 삭제하는 대신 contents 를 삭제하는 이유?
// MainVC 가 호출되면 cache, cookie가 발생하므로 로딩시 확인된 cache, cookie 폴더의
// contents 에 대해서만 삭제 진행.
// Clear web cache
try deleteLibraryFolderContents(folder: "Caches")
// Remove all cookies stored by the site. This includes localStorage, sessionStorage, and WebSQL/IndexedDB.
try deleteLibraryFolderContents(folder: "Cookies")
// Removes all app cache storage.
try deleteLibraryFolder(folder: "WebKit")
} catch {
#if DEBUG
print("Delete library folders error in iOS9 below")
#endif
}
}
}
/**

func deleteLibraryFolder(folder: String) throws {

let dir = library.appendingPathComponent(folder)

} catch where ((error as NSError).userInfo[NSUnderlyingErrorKey] as? NSError)?.code == Int(EPERM) {
// "EPERM: operation is not permitted". We ignore this.
#if DEBUG
print("Couldn''t delete some library contents.")
#endif
}
}

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