Setting the nib file results to the simulator work, but the iPhone device not load.

Question

I set the Target > info > property > main nib file as MainWindow, in the simulator, it works, but in the device, the screen black, and no "viewDidLoad" is called. What's wrong with that? Thank you.

Answer 1

One thing worth checking: did you get the case of the NIB file name correct?

OS X is not case sensitive, so it would consider MainView.xib to be the same as mAiNvIeW.xib but the iPhone is case sensitive, so they'd be considered different files.
