Black UIViewController when pushing but not when presenting modally

I'm having a hard time with a UIViewController...
I have this UINavigationController whose root view controller contains a UITableView which pushes a UIViewController open cell selection.

Sample code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    MySecondViewController *controller = [[MySecondViewController alloc] initWithNibName:@"MySecondViewController" bundle:nil];
    [self.navigationController pushViewController:controller animated:YES];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

Except it doesn't work as expected!
When pushing, it does the animation alright, but instead of my UIViewController there is nothing but a black screen.

The weird thing is that I can present it modally without problem.
I can also push other UIViewControllers without problem!

I looked for other post about such a problem but couldn't find any.
Others seem to have forgotten something like linking their xib or setting the rootViewController or things like that.

Any hints would be greatly appreciated.

Did you check you XIB name "MySecondViewController" ? Is it the exact one ? - βhargavḯ
You are pushing controller or programVC? - NightFury
The UInavigation Controller may cause this issue . Check properly with the UInavigationController . - Kumar KL
you are pushing "programVC" instead of "controller". - Nookaraju
@Bhargavi Yes, I checked my xib, and since it is showing when presented modally I don't think the xib is to blame. And since I can push other view controllers without having the problem I don't see how the navigation controller is to blame. It is a really weird behavior! As for the rest of your hints, sorry guys, I just forgot to change the name of the variable in the sample code I provided. Sure enough I didn't call my controller 'MySecondViewController'. - yonicsurny

Heads up guys, I figured it out!

Turns out, it is a 3rd party lib I was using that caused the problem.
It just got updated and apparently isn't compatible with my implementation.
I still don't know why it failed like that but reverting to a previous version did the trick.
I was initializing it in the viewDidLoadof MySecondViewController.

Thanks for the hints.

Try this. Problem : Wrong VC pushed

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    MySecondViewController *controller = [[MySecondViewController alloc] initWithNibName:@"MySecondViewController" bundle:nil];
    [self.navigationController pushViewController:controller animated:YES];
}
