Does Xcode have code autoformat feature?
Yes Xcode 4 has an autoformat feature.
Try following:
- Select text. CMD+A.
- Press CTRL+I .

One trick is to select the code (either "select all" or just the section you want to re-format) - then cut, then paste it back. This triggers the automatic code formatting in the Xcode editor.
There isn't really an autoformat option in Xcode.
There is an option ^I (Control-I) to re-indent the code, which will re-align the code according to the tab width set in your preferences, but that's about as far as it goes.
You might have better luck with a text editor like TextMate? I don't know for certain, but I know it supports Objective-C and has some macros, there may be a reformat option?
