How to get smart tabs ("indent with tabs, align with spaces") behavior in Xcode?
提问by FreeNickname
I used to use tabs for indentation and spaces for alignment. Like so (arrows show tabs and dots show spaces).
我曾经使用制表符进行缩进，使用空格进行对齐。像这样（箭头表示制表符，点表示空格）。
In QtCreator you can set such coding style in standard preferences. I can't find the way to achieve the same goal in Xcode. Could you please tell me if it is possible? May be there is a plugin for that?
在 QtCreator 中，您可以在标准首选项中设置此类编码风格。我找不到在 Xcode 中实现相同目标的方法。你能告诉我是否可能吗？可能有一个插件吗？
UPDATE:Here is how it can be achieved in QtCreator:
更新：这是在 QtCreator 中实现的方法：
P.S. Please, don't try to persuade me that using spaces only/tabs only is better, otherwise this question will turn into another holywar :)
PS请不要试图说服我只使用空格/制表符更好，否则这个问题将变成另一个圣战:)
Once more about what I'm trying to achieve: Indent with tabs, align with spaces. Vim Tips Wiki.
再次说明我要实现的目标：使用制表符缩进，与空格对齐。Vim 技巧维基。

If you want to remap the standard Xcode's ?+[to TAB, you can do the following:
如果要将标准 Xcode 的?+重新映射[到TAB，可以执行以下操作：
Install a program called "Karabiner".
Go to Preferences ~> "Misc and Uninstall"
In "Custom Setting" section click on the "Open private.xml" button
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>Go to Preferences ~> "Change Key" ~> click on "Reload XML" button
Put a tick in the checkbox which is called "Tab instead of Command+["
Enjoy
安装一个名为“Karabiner”的程序。
转到首选项 ~>“杂项和卸载”
在“自定义设置”部分单击“打开 private.xml”按钮
打开文件并将其内容替换为以下代码：
<?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>转到首选项 ~>“更改密钥”~> 单击“重新加载 XML”按钮
在名为“Tab 而不是 Command+[”的复选框中打勾
享受
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.
PS：请注意，此设置在您的机器上全局有效，而不仅仅是在 Xcode 中。但是，我相信 google 可能会帮助您找到如何进一步自定义它的解决方案，仅将更改应用于 Xcode。
