iOS 使用WKWebView缓存cookie
废话不多说，直接上代码
//插入设置cookie
-(void)insertCookie{
// 创建一个可变字典存放cookie
NSHTTPCookie *cookie =[self setcookie];
if (@available(iOS 11.0, *)) {
WKHTTPCookieStore *cookieStore = self.webView.configuration.websiteDataStore.httpCookieStore;
[cookieStore setCookie:cookie completionHandler:nil];
}
NSHTTPCookieStorage * shareCookie = [NSHTTPCookieStorage sharedHTTPCookieStorage];
[shareCookie setCookie:cookie];
NSMutableArray *TempCookies = [NSMutableArray array];
NSMutableArray *localCookies =[NSKeyedUnarchiver unarchiveObjectWithData: [[NSUserDefaults standardUserDefaults] objectForKey: @"webCookie"]];
for (int i = 0; i < localCookies.count; i++) {
NSHTTPCookie *TempCookie = [localCookies objectAtIndex:i];
if ([cookie.name isEqualToString:TempCookie.name] &&
[cookie.domain isEqualToString:TempCookie.domain]) {
[localCookies removeObject:TempCookie];
i--;
break;
}
}
[TempCookies addObjectsFromArray:localCookies];
[TempCookies addObject:cookie];
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: TempCookies];
[[NSUserDefaults standardUserDefaults] setObject:cookiesData forKey:@"webCookie"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
//清空所有cookie
- (void)clearWKCookies
{
if (@available(iOS 11.0, *)) {
NSSet *websiteDataTypes = [NSSet setWithObject:WKWebsiteDataTypeCookies];
NSDate *dateFrom = [NSDate dateWithTimeIntervalSince1970:0];
[[WKWebsiteDataStore defaultDataStore] removeDataOfTypes:websiteDataTypes modifiedSince:dateFrom completionHandler:^{
}];
}
//删除NSHTTPCookieStorage中的cookies
NSHTTPCookieStorage *NSCookiesStore = [NSHTTPCookieStorage sharedHTTPCookieStorage];
[NSCookiesStore removeCookiesSinceDate:[NSDate dateWithTimeIntervalSince1970:0]];
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: @[]];
[[NSUserDefaults standardUserDefaults] setObject:cookiesData forKey:@"webCookie"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
//删除指定cookie
-(void)deleteCookie{
NSHTTPCookie *cookie =[self setcookie];
if (@available(iOS 11.0, *)) {
//删除WKHTTPCookieStore中的cookies
WKHTTPCookieStore *cookieStore = self.webView.configuration.websiteDataStore.httpCookieStore;
[cookieStore deleteCookie:cookie completionHandler:nil];
}
//删除NSHTTPCookieStorage中的cookie
NSHTTPCookieStorage *NSCookiesStore = [NSHTTPCookieStorage sharedHTTPCookieStorage];
[NSCookiesStore deleteCookie:cookie];
//删除磁盘中的cookie
NSMutableArray *localCookies =[NSKeyedUnarchiver unarchiveObjectWithData: [[NSUserDefaults standardUserDefaults] objectForKey: @"webCookie"]];
for (int i = 0; i < localCookies.count; i++) {
NSHTTPCookie *TempCookie = [localCookies objectAtIndex:i];
if ([cookie.domain isEqualToString:TempCookie.domain] &&
[cookie.domain isEqualToString:TempCookie.domain] ) {
[localCookies removeObject:TempCookie];
i--;
break;
}
}
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: localCookies];
[[NSUserDefaults standardUserDefaults] setObject:cookiesData forKey:@"webCookie"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
-(NSHTTPCookie*)setcookie{
NSMutableDictionary *fromappDict = [NSMutableDictionary dictionary];
[fromappDict setObject:@"fromapp" forKey:NSHTTPCookieName];
[fromappDict setObject:@"ios" forKey:NSHTTPCookieValue];
// kDomain和NSHTTPCookieOriginURL我是指定需要保存的ip
[fromappDict setObject:@"http://www.baidu.com" forKey:NSHTTPCookieDomain];
[fromappDict setObject:@"http://www.baidu.com" forKey:NSHTTPCookieOriginURL];
[fromappDict setObject:@"/" forKey:NSHTTPCookiePath];
[fromappDict setObject:@"0" forKey:NSHTTPCookieVersion];
// 将可变字典转化为cookie
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:fromappDict];
return cookie;
}
最后就是调用了，如图所示，将cookie添加到webview的configuration，最后webview加载request即可
