Question

I want programatically switch from one view controller to another. I use the following code :

SenderPlayerViewController *myViewController = [[SenderPlayerViewController alloc] init];
[self.navigationController pushViewController:myViewController animated:YES];

but I get a black screen, while I have already put some controls in SenderPlayerViewController.

Are u trying to instantiate with an nib file? If so, you must use initWithNibName:bundle:


SenderPlayerViewController *myViewController = [[SenderPlayerViewController alloc] initWithNibName:@"SenderPlayerViewController" bundle:nil];

Also with a story board it is not enough to call alloc init on a controller class.

It should be something like

UIViewController *viewController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:NULL] instantiateViewControllerWithIdentifier:@"SenderPlayerViewController"];
