Second nib in multiview not displaying

ManWithMask · 03-27-2010, 11:36 AM

I'm a newbie to this.

I have double checked my IB setup and it looks correct. I have followed just about every video on this topic, so I think I am good to go. The navigation worked once through all 10 screens I have. Somehow I must have done something stupid. I have been sitting on this for 3 days...so the problem is likely small, but frustratingly huge.

I have a multiview app, using controllers and buttons to switch between views. The second view (MyDetails) displays as a white screen (blank).

Here is my code until the 2nd view. Perhaps someone can see something I don't see. I would really appreciate some help please!

Happy to send the code to those who really want to help me.

I found the problem...stupid...I had the initWithNibName:nil instead of setting it to my actual nib @"" name.
