如何在 Xcode 中找到行号？

Question

I have a function in my *.m file

- (void)myFunction {}

How can I find the line number this function?

Answer 1

You can go to:

Xcode > Preferences > Text Editing

then tick "Line numbers". Go to your method and you'll see the appropriate line number shown in the left-hand border of the text editor.

Answer 2

转到 Xcode Preferences > Text Editing > Show: Line numbers 以在编辑器上显示行号。

Answer 3

This can also be done through code when your implementation file grows. I have found this very useful to track and debug through tedious code. NSLog(@"\\nFunction: %s\\t\\tLine: %d\\n\\n", func , LINE );

For example, in some class called MyClass:

- (void) someFunction {
    NSLog(@"\nFunction: %s\tLine: %d\n\n",__func__, __LINE__);
}

==== Output ===

Function: -[myClass someFunction]          Line: 175

Answer 4

如果键入 command L 并输入所需的行号，则可以跳转到 Xcode 5 中的行号。

Answer 5

In Xcode 7

Xcode > Preferences > Text Editing
check the Line numbers

Answer 6

Still applies in Xcode 8

Xcode > Preferences > Text Editing

Answer 7

Shortcut cmd+L . Enter line number.

or

cmd+O . $CLASS_NAME:$LINE_NUMBER.

And your XCode goes to the line and highlights it!

Answer 8

Keep Xcode top on Mac-Screen than press "command" and "comma key btn" a xcode preferences popbox will open given below: than click on "Text Editing" menu below given window will open here you on top written "show" with "Line numbers" just check it and thats it.

Happy Coding!!!
