This is pretty old Pull Request, here's explanation why it's still not merged:
HKTMXTiledMap is designed to be better CCTMXTiledMap, but it doesn't support isometric nor hex orientation.
Probably we should improve it to support these orientations and try to merge it to cocos2d-iphone, instead of extensions, as a patch/improvement for CCTMXTiledMap.

So, it's not merged because:

1. It should support all orientations to become complete.
2. It looks more like a patch, not an extension.

This Pull Request will remain open however, because:

1. We need a place to discuss it & improve & merge if we will decide so.
2. Someone may find this usefull, so extensions repo will promote it a little.

@everyone, feel free to share your thoughts about this.
Thanks!

I agree with some of the sentiments suggested here, however:

1. Supporting iso and hex would be nice, but I'm afraid my familiarity with the 2 are completely foreign. In theory it would be as making sure the layout of the grid was okay, and then figuring out the proper clipping. The proper clipping can be difficult. It's rather easy for ortho (for obvious reasons).
2. Not feature complete with the latest TMX specification (lacks flip)
3. It does have some open bugs that I really should just hunker down and fix, but as they rarely are an issue in my current project,
   3a) blank layers aren't allowed (should be a simple fix)
   3b) requires POT texture (unsure if this is HKTMX or a CCTMX requirement)
   3c) http://www.cocos2d-iphone.org/forum/topic/17945/page/2#post-114731 I have no idea why the hell THAT particular one happens.
   3d) people want features like the ability to call tileAt: However, that just doesn't work in the nature of HKTMXTiledMap (things aren't ccsprites). That alone breaks the API.
