try as below
尝试如下
UIViewController *bbp=[[UIViewController alloc]initWithNibName:@"UIViewController" bundle:nil];
UINavigationController *passcodeNavigationController = [[UINavigationController alloc] initWithRootViewController:bbp];
// [self.navigationController presentModalViewController:passcodeNavigationController animated:YES];
[self.navigationController pushViewController:passcodeNavigationController animated:YES];
[passcodeNavigationController release];

Add this code to your AppDelegate.min the didFinishLaunchingWithOptionsfunction:
将此代码添加到您AppDelegate.m的didFinishLaunchingWithOptions函数中：
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"YOUR_STORYBOARD_NAME" bundle:nil];
yourViewControllerClassName *vc = [sb instantiateViewControllerWithIdentifier:@"YOUR_VIEWCONTROLLER_ID"];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:vc];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
yourViewControllerClassNameis the .h and .m file name that is linked to your viewController.
yourViewControllerClassName是链接到您的 viewController 的 .h 和 .m 文件名。
YOUR_STORYBOARD_NAMEis the name of your .storyboard file. For example, fill in Mainif your .storyboard file is called Main.storyboard.
YOUR_STORYBOARD_NAME是 .storyboard 文件的名称。例如，Main如果您的 .storyboard 文件名为，请填写Main.storyboard。
YOUR_VIEWCONTROLLER_IDis the ID for your veiwController. You can edit it in the Identity inspector.(See photo)
YOUR_VIEWCONTROLLER_ID是您的 veiwController 的 ID。您可以在Identity inspector.（见照片）中对其进行编辑
Hope this helps:)
