Should views be created using NIBs or code in iPhone?

Question

Are there any performance, development drawbacks or advantages when designing views using Interface Builder?

Answer 1

One drawback is that it is easy to miss wiring up an outlet or action, and troubleshooting this can be painful. Two positives are that positioning, aligning, and anchoring UI elements is much, much easier, and elements redraw themselves when the phone is rotated (which is an animation process you would otherwise need to handle yourself with programmatic elements).
