UIWebview 不是持久性 cookie

Question

我的应用程序有 2 个故事板，它们使用相同的代码，设计方式相同，但一个用于 ipad，一个用于 iphone。 iPhone 故事板工作正常，但 iPad 故事板在变得不活动时无法保留它的 cookie（称为通知中心，暂停应用程序到后台并再次启动，等等）据我所知它应该工作正常。有人愿意看一下并帮助我吗？提前致谢！

变得活跃：

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    self.user.loggedOut = [defaults objectForKey:@"loggedOut"];
    Database* db = [[Database alloc] init];

    //Get Node from voffice
    NSString* hostStr = [NSString stringWithFormat:@"************?klantnaam="];
    //NSLog(@"host string:%@", hostStr);
    NSData* dataURL = [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]];
    NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];
    //NSLog(@"Server output:%@", serverOutput);
    NSArray *output = [serverOutput componentsSeparatedByString:@"|"];
    self.nodeNummer = output[0];

    if([db checkConnection]){

        // Reset badge number to 0
        [UIApplication sharedApplication].applicationIconBadgeNumber = 0;

        self.user = [db checkAppStart];
        BOOL userCheck = FALSE;

        // IF NO USER IN LOCAL DATABASE
        if(self.user != NULL){
            userCheck = TRUE;
        }

        //TRUE = mainNavigator / FALSE = loginView


        if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
            NSString *segueId = userCheck ? @"mainNavigator" : @"loginView";
            UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPad" bundle:nil];
            UIViewController *initViewController = [storyboard instantiateViewControllerWithIdentifier:segueId];

            if(userCheck){
                [self.window setRootViewController:initViewController];
