以下步骤:

去xcode_preferences->然后选择字体和颜色->选择所有的文本选项->点击字体部分，改变你想要的字体

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?

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。

我还发现，您可以更改由“打印”主题控制的打印字体。我希望打印输出与默认值相同，但是使用更大的字体。

将“打印”重命名为“printing1”(选择打印主题并单击它，它应该允许您更改名称)。 点击“+”，从“New Theme from Template”选择“Default” 重命名为“印刷” 点击字体区域的“Source Editor”和cmd-A选择所有字体 通过点击“T”图标并选择所需的字体大小，将字体大小更改为所需的值(我喜欢12点)

在此之后，打印输出应该匹配新的“打印”模板(即颜色和更大，或无论你如何制作模板)，关键是打印从“打印”主题中获取其格式。

去XCode >首选项>字体& 颜色 双击字体条目以获得字体检查器窗口 选择您想增加/减少大小的所有字体条目 在字体检查器窗口中选择相同的字体(例如:All Fonts > Menlo > Regular > 14)

小心，因为没有撤销!

进入Xcode -> preference ->字体和颜色，然后选择一个演示。字体会自动放大。
