在我的项目中我正在从webservice解析json并在屏幕上显示,我正在使用stroyboards进行我的项目,在我的登录pagem输入用户详细信息后解析json,我收到状态为1它将转到下一页,否则它将显示错误信息。现在我的问题是它检查状态但下一页没有加载。我正在使用导航控制器这是代码,我试图加载视图控制器,但它无法正常工作

我来到这里
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
// Get instance of initial Viewcontroller from storyboard
UINavigationController *navController = self.navigationController;
// Get instance of desired viewcontroller
RTCommunityViewController *viewController =[storyboard instantiateViewControllerWithIdentifier:@"community_id"];
//viewController.kApiKey = apikey;
//viewController.kSessionId = sessionid;
//viewController.kToken = token;
[self.navigationController pushViewController:viewController animated:NO];
}
我无法通过instatinating加载viewController。 View Controller is not pushing
请帮我怎么做。在此先感谢

尝试
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil];
UINavigationController *navController = self.navigationController;
RTCommunityViewController *viewController =[storyboard instantiateViewControllerWithIdentifier:@"community_id"];
//Comment this
//[self.navigationController pushViewController:viewController animated:NO];
[self performSegueWithIdentifier:@"community_id" sender:self];

也许你应该再次检查你的故事板?您是否忘记在所有场景的身份检查器中设置自定义类和StoryboardID?
在视图控制器的类似情况下,这段代码对我有用:
RTCommunityViewController *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"community_id"];
[self.navigationController pushViewController:viewController animated:NO];
