This may not have been pointed out to you, but we do have a style guide for Objective-C code here:
https://github.com/wordpress-mobile/WordPress-iOS/wiki/WordPress-for-iOS-Style-Guide

I mention it here because there are a few spacing discrepancies in this method. A full pass for style in your changes would be good (I won't comment on style any more). It may seem like a small thing, but when multiple people are all contributing to the same files, it helps a lot with everyone's sanity.
