I have an application in which I would like to support multiple orientations. I have two .xib files that I want to use, myViewController.xib and myViewControllerLandscape.xib. myViewController.xib exists in project/Resources and myViewControllerLandscape.xib exists in the root project directory. What I want to do is use a separate NIB (myViewControllerLandscape.xib) for my rotations. I try detecting rotation in viewDidLoad like this: if((self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)) { NSLog(@"Landscape detected!"); [self initWithNibName:@"myViewControllerLandscape" bundle:nil]; } But I can see in gdb that this isn't executed when the app is started with the device in landscape. The NSLog message doesn't fire. Why is this? What have I done wrong? Also, if I explicitly put the initWithNibName function call in the viewDidLoad method, that nib is not loaded,

As a beginning developer I'm wondering what the pros and cons are of using Storyboard vs. .nib files to build app interfaces. I'm aware that: Storyboards supposedly streamline the process of creating interfaces Apps created with storyboards are not compatible with devices running pre-iOS 5 However, I'd like to ask people with experience what the unforeseen drawbacks or advantages may be to using one method over the other, and what experienced developers recommend starting out on. (I'll be developing both for personal and commercial use.) Thank you very much!
