Time for action – completing the NewDefaults.h interface definition


Now that we have created a basic "stub" interface that Xcode will build successfully, we need to go back and fill in the final details to complete our interface definition:

  1. Open the NewDefaults project in Xcode.

    Note

    Often when we are developing program code it needs to contain literal values – for example, a number or strings. Rather than using literal values in the body of our code, we will define symbols in our .h file and then use those symbols in the body of our program code.

  2. Click on the NewDefaults.h file and add the following code to define the literal values that we are going to be using in the body of our code. Now is a good time to read the comments in the program code (the lines that start with //) that precede each #define so that we know what each defined symbol represents.

    Tip

    #define SYMBOL LiteralValue

    The #define compiler directive allows us to define SYMBOLS that we can use in the body of our code. When we build...
