I’ve started using#pragma markdirectives in my code to help with organization as my implementation files grow. #pragma mark is simple to use, for example, insert the following to call out initialization code:

#pragma mark -
#pragma mark Initialization

Once this is in place, the Functions Menu (in the navigation bar) which shows a list of locations within a source file (e.g. definitions of classes, functions and methods) will display a new marker with the label "Initialization." The code in line 1 will add a line separator inside the Functions Menu, in this example, with the line appearing above the "Initialization" marker.

The figure that follows shows an example of how you might use #pragma mark to divide up various sections of your code.

Two notes:

You cannot have a space after the "-" in the#pragma mark -
If your code does not appear as expected (e.g. the separator does not appear), check that ‘Sort list alphabetically’ isnotchecked in the Code Sense preference settings.
