2.8. static

The static keyword in C has some additional meanings and is not used the way it is in Java. Java uses static to declare a single persistent class variable within a class declaration. Objective-C does not allow you to declare variables in a class definition. Instead, static variables are declared as global C variables or static variables inside a code block. Listing 2-13 declares two static variables.

Example 2.13. Global Static Variables

int scramingZombieHitCount = 1;          // accessible from all modules

static int screamingZombieBounceCount;    // accessible only from this module
