How to add iPhone SDK classes to autocomplete in TextMate?

How, if possible, can I have iPhone SDK's classes (UI*) to autocomplete inside TextMate?

From stackoverflow

• Try out the link at the bottom of this thread:

• Ok, after looking the link Kendall posted and some other places this is what I have found:

  There is currently NO easy way to have autocomplete of iPhone APIs in TextMate.

  The link on the post Kendall pointed is old, but I found it and one other iPhone Bundle on gitHub: http://github.com/Caged/gtbfm-textmate-bundle
  http://github.com/drnic/objective-c-iphone-tmbundle

  But none of these bundles offers autocomplete, they have some templates and snippets.

  The closest I have found is on the svn repository from TextMate: http://svn.textmate.org/trunk/Review/Bundles/iPhone.tmbundle

  It's not official yet, and I have reported some issues with it to the developer (Joachim Mårtensson). You can have autocomplete with this bundle, but it is working only with classes files, not headers.
