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 >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!

对于 XCODE 13+

在最新版本的编辑器(目前Xcode 13)中，只需按“cmd”+“+”来增加文本大小。减少文本大小按“cmd”+“-”。事情就是这么简单。除此之外，你可以在Xcode Preferences -> Themes中为每个类别指定文本大小/字体/颜色。

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):

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。

之前所有的答案都集中在可能发生的事情上:改变编辑器和调试区域的字体大小。但是如果你共享你的屏幕导航器(文件导航器等)仍然很小。您现在可以在设置>一般>导航器大小中更改三个预设大小。

这将使你的文件和文件夹在展示时更具可读性。
