Question

 SecondViewController *testAppViewController2Obj =[[SecondViewController    alloc]initWithNibName:@"TestAppViewController2" bundle:nil];
[self.navigationController pushViewController:testAppViewController2Obj animated:YES];

Answer 1

ContainerViewController *container = [[ContainerViewController alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:container];

    UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 65)];

container.navigationItem.title = @"Frames";
     self.window.rootViewController = nav;

我希望它有效

为了推送新的视图控制器，首先应创建一个视图控制器VC1，将其与导航控制器链接，然后将导航控制器链接到AppDelegate中的rootViewController

 #AppDelegate
 FirstViewController  *VC1 = [FirstViewController new];
 UINavigationController *nVC = [UINavigationController alloc] initWithRootViewController:VC1];
 self.window.rootViewController = nVC;

然后当推送VC1时，您可以创建另一个视图控制器并按下这样推送：

 #Now in VC1
 SecondViewController *VC2 = [SecondViewController new];
 [self.navigationController pushViewController:VC2 animated:YES];

导航控制器不使用故事板
