您好，我使用此代码仅使用代码而无需 segue 即可进入新的 Controller 。

    UIStoryboard * mainstoryb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController * vc = [mainstoryb instantiateViewControllerWithIdentifier:@"online_shop"];
[self presentViewController:vc animated:YES completion:nil];

如何在下一个 View 中显示导航栏或标题栏？

您需要如下呈现 NavigationController:

 UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:ContactUSVCID];
 UINavigationController *objNav = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:objNav animated:YES completion:nil];
