现在我是这样做的
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
[storage deleteCookie:cookie];
}
但它不适用于 iOS 8、64 位设备。
WKWebview 的 clean cookie 有什么其他方式吗？任何帮助将不胜感激。谢谢。
Apple 为 iOS 9 和更新版本 发布了新的 API，因此现在我们可以使用以下代码删除为 WKWebView 存储的特定于域的 cookie。
Swift 4/5 版本：
let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
dataStore.removeData(
ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
for: records.filter { $0.displayName.contains("facebook") },
completionHandler: completion
)
}
以下是Swift 3版本
let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { (records) in
for record in records {
if record.displayName.contains("facebook") {
dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), for: [record], completionHandler: {
print("Deleted: " + record.displayName);
})
}
}
}
Objective-C 版本 -
WKWebsiteDataStore *dateStore = [WKWebsiteDataStore defaultDataStore];
[dateStore
fetchDataRecordsOfTypes:[WKWebsiteDataStore allWebsiteDataTypes]
completionHandler:^(NSArray<WKWebsiteDataRecord *> * __nonnull records) {
for (WKWebsiteDataRecord *record in records) {
if ( [record.displayName containsString:@"facebook"]) {
[[WKWebsiteDataStore defaultDataStore]
removeDataOfTypes:record.dataTypes
forDataRecords:@[record]
completionHandler:^{
NSLog(@"Cookies for %@ deleted successfully",record.displayName);
}
];
}
}
}
];
上面的代码片段肯定适用于 iOS 9 及更高版本。不幸的是，如果我们在 iOS 9 之前的 iOS 版本中使用WKWebView，我们仍然必须坚持传统的方法并删除整个 cookies 存储，如下所示。
NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *cookiesFolderPath = [libraryPath stringByAppendingString:@"/Cookies"];
NSError *errors;
[[NSFileManager defaultManager] removeItemAtPath:cookiesFolderPath error:&errors];
Swift 3版本Sarat的回答：
let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { (records) in
for record in records {
if record.displayName.contains("facebook") {
dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(), for: [record], completionHandler: {
print("Deleted: " + record.displayName);
})
}
}
}
支持iOS 11.0及以上版本
以下解决方案对我很有效：
步骤 1. 从
HTTPCookieStorageStep 2. 从
WKWebsiteDataStore第 3 步。创建一个新的
WKProcessPool创建 WKWebView 扩展：
extension WKWebView {
func cleanAllCookies() {
HTTPCookieStorage.shared.removeCookies(since: Date.distantPast)
print("All cookies deleted")
WKWebsiteDataStore.default().fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
records.forEach { record in
WKWebsiteDataStore.default().removeData(ofTypes: record.dataTypes, for: [record], completionHandler: {})
print("Cookie ::: \(record) deleted")
}
}
}
func refreshCookies() {
self.configuration.processPool = WKProcessPool()
}
}
用法：
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
webView.cleanAllCookies()
webView.refreshCookies()
}
这些选项都不适合我，但我找到了一个：
let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {
// I have no idea what to do for iOS 8 yet but this works in 9.
}
let webView = WKWebView(frame: .zero, configuration: config)
在iOS9中：
//// Optional data
NSSet *websiteDataTypes
= [NSSet setWithArray:@[
WKWebsiteDataTypeDiskCache,
//WKWebsiteDataTypeOfflineWebApplicationCache,
WKWebsiteDataTypeMemoryCache,
//WKWebsiteDataTypeLocalStorage,
//WKWebsiteDataTypeCookies,
//WKWebsiteDataTypeSessionStorage,
//WKWebsiteDataTypeIndexedDBDatabases,
//WKWebsiteDataTypeWebSQLDatabases
]];
//// All kinds of data
//NSSet *websiteDataTypes = [WKWebsiteDataStore allWebsiteDataTypes];
//// Date from
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
//// Execute
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
// Done
NSLog(@"remove done");
}];
在所有现有答案的基础上，如果您尝试清除特定 WKWebView 实例“webView”的 cookie 和数据记录，而不是“默认”存储的 cookie 和数据记录，您可以使用以下内容：
let dataStore = webView.configuration.websiteDataStore
let cookieStore = dataStore.httpCookieStore
cookieStore.getAllCookies {
$0.forEach { cookie in
cookieStore.delete(cookie)
}
}
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
records.forEach { record in
dataStore.removeData(ofTypes: record.dataTypes, for: [record]) { }
}
}
Swift 4 和更短的版本：
let dataStore = WKWebsiteDataStore.default()
dataStore.fetchDataRecords(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes()) { records in
dataStore.removeData(ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
for: records.filter { $0.displayName.contains("facebook") },
completionHandler: completion)
}
斯威夫特 5
/// old API cookies
for cookie in HTTPCookieStorage.shared.cookies ?? [] {
HTTPCookieStorage.shared.deleteCookie(cookie)
}
/// URL cache
URLCache.shared.removeAllCachedResponses()
/// WebKit cache
let date = Date(timeIntervalSince1970: 0)
WKWebsiteDataStore.default().removeData(
ofTypes: WKWebsiteDataStore.allWebsiteDataTypes(),
modifiedSince: date,
completionHandler:{})
除了清除共享 cookie 存储中的 cookie 之外，我还会尝试清除缓存 (NSURLCache) 并丢弃 WKWebView 并使用新的 WKProcessPool 创建一个新的
似乎 NSHTTPCookieStorage 现在在 iOS 8.2 中被用于根据需要正确清除 cookie。我已经发布了一个应用程序，它会在打开基于 WKWebView 的登录之前运行此代码：
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in [storage cookies])
{
[storage deleteCookie:cookie];
}
在 iOS 8.2 之前，网站会使用保存的 cookie 自动登录，现在它会正确地要求用户重新登录。所有这一切都发生在我没有发布应用程序更新的情况下。 :)
Esqarrouth 的回答只对了一部分。
正确的 swift 版本是：
var libraryPath : String = NSFileManager().URLsForDirectory(.LibraryDirectory, inDomains: .UserDomainMask).first!.path!
libraryPath += "/Cookies"
do {
try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
} catch {
print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()
WKWebview 在 [NSHTTPCookieStorage sharedHTTPCookieStorage] 中不存储任何内容。
清除 WKWebsiteDataStore 将解决这个问题。
还是IOS8使用WKwebview，这个方法不适用..
在 WKWebView 中，写入和读取需要花费一些时间，因此当您有时获取 cookie 时，您会得到更新的 cookie，但有时它会是旧的，并且您会在任何服务器请求上出错。我在 3 天内遇到了这个问题，
解决方案：无需在WKWebsiteDataStore中存储cookie。
获取饼干：
斯威夫特：
extension WKWebView {
private var httpCookieStore: WKHTTPCookieStore { return WKWebsiteDataStore.default().httpCookieStore }
func getCookies(for domain: String? = nil, completion: @escaping ([String : Any])->()) {
var cookieDict = [String : AnyObject]()
httpCookieStore.getAllCookies { cookies in
for cookie in cookies {
if let domain = domain {
if cookie.domain.contains(domain) {
cookieDict[cookie.name] = cookie.properties as AnyObject?
}
} else {
cookieDict[cookie.name] = cookie.properties as AnyObject?
}
}
completion(cookieDict)
}
}
}
目标-c：
-(void )getAllCookies
{
NSMutableString *updatedCockies= [[NSMutableString alloc] init];
if (@available(iOS 11.0, *)) {
WKHTTPCookieStore *cookieStore = _webView.configuration.websiteDataStore.httpCookieStore;
NSLog(@"cookieStore *********************: %@",cookieStore);
[cookieStore getAllCookies:^(NSArray* cookies) {
NSHTTPCookie *cookie;
for(cookie in cookies){
NSLog(@"%@",cookie)
}
self->updatedCookie = updatedCockies;
NSLog(@"cookie *********************: %@", self->updatedCookie);
}];
}
}
每次你想要新的cookie所以你需要写下面的代码： 鉴于夏皮奥
斯威夫特：
let config = WKWebViewConfiguration()
if #available(iOS 9.0, *) {
config.websiteDataStore = WKWebsiteDataStore.nonPersistentDataStore()
} else {

}
let webView = WKWebView(frame: .zero, configuration: config)
目标C--
WKWebViewConfiguration *wkWebConfig = [WKWebViewConfiguration new];
wkWebConfig.websiteDataStore = [WKWebsiteDataStore nonPersistentDataStore];
self.webView = [[WKWebView alloc] initWithFrame: CGRectZero
configuration: wkWebConfig];
*********每次你都会得到新的饼干********
Swift版本：
var libraryPath = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.LibraryDirectory, NSSearchPathDomainMask.UserDomainMask, false).first!
libraryPath += "/Cookies"
do {
let result = try NSFileManager.defaultManager().removeItemAtPath(libraryPath)
print(result)
} catch {
print("error")
}
NSURLCache.sharedURLCache().removeAllCachedResponses()
