Seeing as Nintendo will never release a Pokemon game for Apple hardware, Mobile Monsters is pretty much the closest you're gonna get...
4 new pokemon type games are going to be released at some point. Check the upcoming thread and search for pokemon type or monster catching and you should see 4 at least.

You guys dont have to put up with this "searching for an iphone game like pokemon". There is a game opening soon called micromon. It is almost finished. There is a forum on this website. This is the link: http://forums.toucharcade.com/showthread.php?p=2612714#post2612714
Dragon Island Blue Wonderful Pokemon-esque style game with a few editions. It's a bit confusing at first but it's the closest to Pokemon you'll find. I've beaten the game but there is still an endless dungeon to go through. There is also an update coming out in 1-3 months adding (I think) PvP and trading. Hope this helped
Dragon Island Blue is a pretty cool game, but I think it will never be online. Which is a shame and the only reason I'm not playing it.
