static variables in Objective-C - what do they do?

Question

I\'ve seen a few posts discussing what a static variable is and I think I get it - but I\'d love to quickly write (or find) a program that utilizes both a regular and a stat

Answer 1

static works mostly like in C.

1. It can either initialize a variable only once.

2. Declaring a variable static in a file above @implementationblock will be available for the whole file only.
