Hey, Like most apps, the app that I’m building requires the use of a UITabBarController and UINavigationControllers together. This theoretically is pretty simple; I’ve read the docs, I understand that the UITabBarController holds the collection of UINavigationControllers, and each UINavigationController holds the UIViewControllers necessary to display views. In short, my current design looks like so: -File’s Owner -First Responder -App Delegate -Window -Tab Bar Controller -Tab Bar-First Navigation Controller-Navigation Bar-View Controller-Table View-Navigation Item-Tab Bar Item Where I’m getting confused is when I try to move from a one-nib design to a multi-nib design. I *believe* that a better design would be to have a UITabBarController in a MainWindow.nib and have that nib load other nibs with the UINavigationControllers as needed. So, I create my new nibs, create navigation controllers in the new nibs, tell my UITabBarController Tab Bar Item to look for the nib, and find my app useless. I don’t know what I’m doing incorrectly in my move from one nib to multiple nibs. I’d appreciate any advice or help or guidance that anyone can provide. Thanks in advance.
