To remove the last add viewController from the navigation controller stack use:

[self.navigationController popViewControllerAnimated:YES];

What you are tying to do won't work because you are creating a new instance of the Homepage view controller, which is not in the stack.

popToViewController is expecting a viewcontroller instance which is already in the stack.

If I understand you correctly - you work with UIImagePickerController. So, for hiding this one and navigate to previous viewController just call dismissModalViewControllerAnimated: method

[self dismissModalViewControllerAnimated:YES];
