How can I find a line number in Xcode?

问题

I have a function in my *.m file

- (void)myFunction {}

How can I find the line number this function?

回答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.

回答2:

Go to Xcode Preferences > Text Editing > Show: Line numbers to show the line numbers on the editor.

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

If you type command L and enter the desired line number, then you can jump to the line number in Xcode 5.

回答5:

In Xcode 7

Xcode > Preferences > Text Editing
check the Line numbers

回答6:

Still applies in Xcode 8

Xcode > Preferences > Text Editing
