It won’t be meaningfully different; most of the execution time will be loading the images themselves, rather than your code to create the image views in ObjC or through loading the nib.
So you should do what’s better for your performance as a programmer; typically, if there’s some kind of regular geometric pattern to the positions and names of the objects, code will be easier, but if not, IB will be easier.
