Ios 如何使用sharedHTTPCookieStorage删除cookie数据和用户默认值？

我在

apimager.m

中有一个注册和

loginWithUserName

方法。在

loginWithUserName

方法中，我将cookie设置为：

if ([[responseObject objectForKey:@"status_code"] isEqualToString:kStatusOk]) {
    NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    self.cookie = cookies[0];
    NSLog(@"%@", self.cookie);
    NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject:self.cookie];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:cookiesData forKey:@"savedCookie"];
    [defaults synchronize];
    NSLog(@"%@ \n\n\n RESPONSE OBJECT Obtained \n\n\n",responseObject);
    succes(responseObject);
} else {
    failure(responseObject);
}

我有一个加载保存的Cookie的方法（我在登录或注册后在appDelegate中使用此方法）：

我想创建一个注销按钮，我需要在我的apimager.m中使用一个方法来删除cookies。

要清除NSUserDefault：

NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies]) {
    [storage deleteCookie:cookie];
}

NSString *domain = [[NSBundle mainBundle] bundleIdentifier];
[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:domain];

NSString *domain = [[NSBundle mainBundle] bundleIdentifier];
[[NSUserDefaults standardUserDefaults] removePersistentDomainForName:domain];
