Where do I find the line number in the Xcode editor?
提问by William Jockusch
In Xcode 3, the line number of the current cursor location was displayed. I don't see this in Xcode 4. Is there a setting that will turn it on? Or a keypress that will give it to me?
在 Xcode 3 中,显示了当前光标位置的行号。我在 Xcode 4 中没有看到这个。有没有设置可以打开它?或者给我一个按键?

In Preferences->Text Editing-> Show: Line numbers you can enable the line numbers on the left hand side of the file.
在首选项-> 文本编辑-> 显示:行号中,您可以启用文件左侧的行号。

Sure, XCode->Preferences and turn on Show line numbers.
当然,XCode->首选项并打开显示行号。

If you don't want line numbers shown all the time another way to find the line number of a piece of code is to just click in the left-most margin and create a breakpoint (a small blue arrow appears) then go to the breakpoint navigator (?7) where it will list the breakpoint with its line number. You can delete the breakpoint by right clicking on it.
如果您不想一直显示行号,另一种查找代码行号的方法是单击最左边的边距并创建一个断点(出现一个蓝色小箭头),然后转到断点navigator ( ?7) 它将列出断点及其行号。您可以通过右键单击断点来删除断点。
