如何删除WKWebview cookie
如何删除WKWebview cookie
提问于 2015-07-08 10:22:10
现在我是这样做的
NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
[storage deleteCookie:cookie];
}但它并不适用于64位的iOS 8设备.
WKWebview的干净饼干还有别的办法吗？任何帮助都将不胜感激。谢谢。

苹果为iOS 9发布了新的API，因此现在我们可以用下面的代码删除WKWebView存储的特定域cookie。
迅速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);
})
}
}
}目标-C版-
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);
}
];
}
}
}
];上述代码段肯定适用于、iOS 9、及更高版本。不幸的是，如果我们在 iOS 9之前使用iOS版本的iOS，我们仍然必须坚持传统的方法，删除整个cookie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];Stack Overflow用户

Swift 3版Sarat的答案：
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及以上的
以下解决方案对我来说效果很好：
步骤1.从HTTPCookieStorage中删除Cookie
步骤2.从WKWebsiteDataStore中获取数据记录并删除它们。
步骤3.创建一个新的WKProcessPool
创建一个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()
}
}使用：
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
webView.cleanAllCookies()
webView.refreshCookies()
