macbook enough for iphone app development ?

I decided to try selling few shitty apps after having seen what crap people acutally buy, tho it seems I need a macbook to make those

I don't want to buy an iphone on top of it so is the emulator thingy enough for development ?

You only need to use Objective-C if you want to use a native UI. Otherwise you can just code in OpenGL.
