Like many, I use the popular open-source text editor vim. Earlier, I set about making it more usable through syntax coloring. This included tweaking its support for Objective-C.
First, mkdir ~/.vim, and cd ~/.vim. Now mkdir syntax. cp /usr/share/vim/vim62/filetype.vim . and cp /usr/share/vim/vim62/syntax/objc.vim syntax/. Then select and copy this patch:

OK, now you have modified copies of the file type detector and the Obj-C syntax coloring. Now you need a .vimrc. If you already have one, add this to it; otherwise, create it with this:
let c_gnu=1
let c_no_bracket_error=1
let objc_syntax_for_h=1
syntax enable
This makes the following changes:
- c_gnu
- Enables detection of some GCC extensions to C.
- c_no_bracket_error
- Allows
{} inside of []. This lets you do compound literals inside messages; for example: [self setFrame:(NSRect){ NSZeroPoint, (NSSize){ 128.0f, 128.0f } }];
- objc_syntax_for_h
- Tells vim (with my modifications, that you did above) that a .h file is an Obj-C header, not a C++ header.
- syntax enable
- Enables syntax-highlighting.
