Time for action – writing the readDefaults:forKey: program code

Now we can jump in and write the program code to implement this method as follows:

  1. Start by putting a comment in the NewDefaults.m file that describes the method in plain English:

    /*
    This method will execute the command line tool defaults
    to read a value from a domain for a specific key
 
    Input: 
        a_domain - a reverse domain id for the defaults to read
        a_key - a key value to read
 
    Output:
        Either the string value of the result or Nil if there
        is no value to return.
 */

    Tip

    It's always a good idea to explain our methods using this kind of plain English comment block.

  2. The method needs to match the interface from the .h file. So now we can add the function body to the .m file. Note the opening and closing braces that delimit the start and the end of the method. The implementation of the method will appear between these braces as shown in the following code snippet:

    - (NSString *) readDefaults...
