About nib files

[mikezang]

I found two examples of "Hello World", one has nib files, one has no.

What is the difference between with or without nib?

The simplified difference is whether you want to code your interface programmatically (without nibs) or via Interface Builder (with nibs). And you can also mix-and-match. Some parts done with nibs, others not. You can even alter the interface specified by the nib after the fact via the program.

I found the upgrade to universal project for both iPad/iPhone is not work when a project with nib files, it seems like the nib files are not displayed, only black screen showed.

Do you know why?

Since you already have an existing thread on this topic, let's restrict discussion of this issue in there. And, no, I don't know why.

I asked again, because experts answer my question
