Given that the technologies available to anyone involved in writing software are constantly evolving, I would expect that anyone writing software would be searching the internet for relevant information on a regular basis. Given that you are working with Objective-C, I'm guessing you're writing for one of the Apple device platforms, which is an area of software development that is relatively new - and under these circumstances, I'd expect that you'd be looking for information on a regular basis.
I think that there is a tendency to associate (or, confuse) searching the internet for information with mindless "web-surfing", which could make individuals who are legitimately searching for information feel odd at work. But think of it this way - before good search engines, you would have picked up a reference book - and I don't know that I would have looked at you cross-eyed for doing so.
Besides, how does anyone learn anything without at least doing some self-directed reading of some kind? I write software in an interdisciplinary environment where I can't afford to have a "favorite" platform or language - I have to use what makes the most sense for the project at hand - which means I'm always looking for information because I'm constantly learning. :-p
