How to convert word to lower or upper case in xcode?

[iwind]

In xcode editor, i want to change a piece of code to upper case, how can i do it quickly? such as change " my_tunner_charge" to "MY_TUNNER_CHARGE"?

There is any hotkeys? Or xcode never support this?

Same way you would in every program ~ use Find & Replace and turning off the ignore case option. Just hit command F to bring it up for one doc, command-shift F for multiple documents.

Thank you for replying! In fact, in some other IDEs(on Windows Operation System), i only need to press CTRL+L to make the selected words to lower case, and CTRL+U to make them to upper case.

Find & Replace maybe a choice, but i have to knock keys and input the word AGAIN!

Is there a shortcut to do this, just like CTRL+L and CTRL+U?

I'm not aware of a default key in Xcode to do this, but I've reprogrammed several keys to make my life easier.

There's a great post on this subject here:

Mac OS X Key Bindings - Erasetotheleft

One of their examples covers your exact requirement...

...
"~u" = "uppercaseWord:"; /* M-u */
"~l" = "lowercaseWord:"; /* M-l */
...

If you only want the definition to apply to Xcode, you need to modify (create if it doesn't exist):

~/Library/KeyBindings/PBKeyBinding.dict

There are good discussions of this here:

TypeOneError Studios™ Custom Key Bindings in XCode for TextMate users

and here:

After following the two links mentioned, I can use CTRL+SHIFT+U/L to change the words' case now!

Thanks you.

The last thing I need to point out is I MUST use Xcode Default Key Binding Sets, or It will do not work.

I'm glad that the technique worked for you. It's nice to have the key mappings that we love.

Go into xcode preferences -> KeyBindings ->Text Key Bindings -> Capitialize Word -> assign a key

now it'll uppercase when you select some text in the xcode editor and hit your assigned key

Setting the Capitalize Word key will change the first letter of the word to capital. If you want to change all letters in a selection to capitals or lowers, then set a couple of keys for the Uppercase Word and Lowercase Word choices in Text Key Bindings.

i.e., Go into xcode preferences -> KeyBindings ->Text Key Bindings -> Uppercase Word -> assign a key

and

Go into xcode preferences -> KeyBindings ->Text Key Bindings -> Lowercase Word -> assign a different key
