How can I indent multiple lines in Xcode?

问题

When I select multiple lines of code and want to indent them as usual with TAB key, it just deletes them all. I come from Eclipse where I always did it that way. How's that done in Xcode? I hope not line by line ;)

回答1:

The keyboard shortcuts are ⌘+] for indent and ⌘+[ for un-indent.

• In Xcode's preferences window, click the Key Bindings toolbar button. The Key Bindings section is where you customize keyboard shortcuts.

回答2:

Select your code to reindent, then Go to

Editor -> Structure -> Re-Indent

回答3:

⌘ + [ and ⌘ + ] are the equivalents to shift+tab in Xcode.

Here are the shortcuts, to format the code in XCode

1. Format entire code (entire class/controller)

   Select the entire code and press control+I on mac to format your code.

2. Format particular block of code

   Select the code and press:

   • ⌘+] for right move (indent)
   • ⌘+[ for left move (un-indent)

Note: as per @JavierGiovannini sugesstion you can do using Editor Menu option

3. Select your code and navigate to Editor > Structure > Re-Indent

回答5:

Another way to quickly reformat indenting is a quick cut and paste. ⌘+x and ⌘+v. I often find it faster than ⌘+[ or ⌘+] as you can do it with one hand (versus two) and it will reformat to the correct indent level in one shot.

If you use synergy (to share one keyboard for two PCs) and PC(MAC) in which you are using xcode is slave, and master PC is Windows PC

keyboard shortcuts are alt+] for indent and alt+[ for un-indent.

Update:

But from synergy version 1.5 working ⌘+[ for indent and ⌘+] for un-indent

In Xcode 9, you can finally use Tab and Shift+Tab to indent multiple lines of code. Yay!

回答8:

First, select all code using command+a

Second, hold key ctr and then press i

the whole selected code will nicely indent.

回答9:

Select "Tab key: Indents always" in Preferences->Text Editing->Indentation Then you can indent a single line or a selection of lines by pressing TAB or SHIFT+TAB Sadly this removes altogether the possibility to insert tabs where you want, and conflict badly with the tab key being used to switch between "autocompletion fields".

I guess we need more tab keys in the keyboard, one is not enough...

For those of you with Spanish keyboard on mac this are the shortcuts:

⌘ + ⌥ + [ for un-indent

⌘ + ⌥ + ] for indent

If you want to remap the standard Xcode's ⌘+[ to TAB, you can do the following:

1. Install a program called "Karabiner".

2. Go to Preferences ~> "Misc and Uninstall"

3. In "Custom Setting" section click on the "Open private.xml" button

4. Open the file and replace its content with the following code:

   <?xml version="1.0"?> 
   <root>
       <item>
           <name>Tab instead of Command+[</name>
           <identifier>private.swap_tab_and_cmnd+[</identifier>
           <autogen>
               __KeyToKey__
               KeyCode::TAB, ModifierFlag::NONE,
               KeyCode::BRACKET_RIGHT, ModifierFlag::COMMAND_L | ModifierFlag::NONE
           </autogen>
       </item> 
   </root>
   

5. Go to Preferences ~> "Change Key" ~> click on "Reload XML" button

6. Put a tick in the checkbox which is called "Tab instead of Command+["

7. Enjoy

PS: Please note that this setting works globally on your machine, not just in Xcode. However, I am sure that google might help you to find a solution how to customize it even further, applying the changes only to Xcode.

Danish Keyboard

Unindent: ⌘ + ⌥ + 8

Indent: ⌘ + ⌥ + 9

回答15:

Basically ⌘ [ for left multiple indent and ⌘ ] right multiple indent.

For TR keyboard you can left multiple indent with ⌘ ⎇ 8 and right multiple indent with ⌘ ⎇ 9.Because both 8 and 9 are ALT characters of the these nums.Or if you have a keyboard which has [ or ] characters are belong to ALT(⎇) property so you can use ⌘ ⎇ KEYBOARD CHARACTER

回答16:

The shortcut to re-indent is: control + i

回答17:

Since I didn't see an update to this question for the current version of Xcode, I thought I'd add that in Xcode 9.3, Tab works for indenting selected line(s) of text as well as moving from one autocomplete field to another.

回答18:

Tab for Indent SHIFT + Tab Re-indent

回答19:

In Xcode 4.2 auto-indenting is pretty good. You can now indent a selection of code by pressing the Tab key. I find that Xcode generally formats code really well automatically, and you rarely have to move things around yourself. I find it faster to select a piece of code, right-click and choose Structure -> Re-indent if some code looks messy.
