如何在WKWebview中删除缓存？
提问于 2014-11-24 20:39:47
是否有人使用WKWebview并试图清除缓存？如果是，该怎么办？有什么例子吗？
P.S. : Normal NSURLCache不工作。

更新后的Swift 5版本：
WKWebsiteDataStore.default().removeData(ofTypes: [WKWebsiteDataTypeDiskCache, WKWebsiteDataTypeMemoryCache], modifiedSince: Date(timeIntervalSince1970: 0), completionHandler:{ })Swift版本：
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()
}Swift 3版本：
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()

在iOS 9中
// 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

删除缓存和Cookie
# WKWebView+Clean.swift
import WebKit
extension WKWebView {
class func clean() {
guard #available(iOS 9.0, *) else {return}
HTTPCookieStorage.shared.removeCookies(since: Date.distantPast)
WKWebsiteDataStore.default().fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
records.forEach { record in
WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record], completionHandler: {})
#if DEBUG
print("WKWebsiteDataStore record deleted:", record)
#endif
}
}
}
}示例：
import WebKit
