对于Xcode 12:(beta 3)

对于代码编辑窗口，请使用new

编辑器->字体大小->增加

or

编辑器->字体大小->减少

菜单项。这将全局地增加或减少所有编辑窗口的字体大小。还有一个

编辑器->字体大小->重置

选择。这些也响应⌘+或⌘-键盘快捷键。

默认情况下，左侧的文件导航器对应于

系统首选项->常规->侧栏图标大小

你也可以在Xcode中使用

Xcode -> Preferences -> General -> Navigator Size

去

Xcode menu > Preferences > Font & Color > Category

双击纯文本，弹出菜单将出现。从这里开始改变。

对于Xcode 4.1

仍然是一个巨大的痛苦。糟糕的UI设计(但我的心态似乎与那些制作100多个字符变量和方法名的软件工程师的心态不一样。我的抱怨够多了)

我将为当前版本修改以前的一篇文章。

Close any projects you have open in Xcode (Otherwise the Font window will be inaccessible while a project is open.) Go to XCode > Preferences > Fonts & Color From the 'Theme' box select the theme you want to modify (or select the theme you want to modify and click the "+" button at the bottom of the theme list to clone it first for backup, for there is no undo option) In the source editor box there is a list of types of text that you may set the font for: Plain text Comments Documentation Comments . . . Select any or all items from the source editor list and the name and size of the font for that particular text will show up in the 'Font' window below the 'Source Editor' window. (If you happen to skip highlighting one of these, you will be able to get to the Font Inspector and select new sizes, but will wonder why the changes you make are not being applied!) In the 'Font' window, click the small, almost hidden, and surely poorly design 'T' icon to the right of the font name and size. Voila! In only 14 keystrokes you are able to get the Font inspector window! Your existing font will be preselected in the font inspector. Whatever changes you make now will be applied to the text types you selected in the 'Source Editor' window. e.g. All Fonts > Menlo > Regular > 14 Close the windows you opened on this hunt for the holy grail.

祝贺你。你现在可以阅读你的代码了。 这难道不痛苦吗?

您可以使用此插件使用⌘+或⌘-(最新版本的Xcode中的Control -和Control +)更改字体大小。插件开发人员更改了快捷键，以避免与Interface Builder热键冲突):
