Question

what is the proper way to do If statement with two variable in Xcode for Iphone

currently I have

if (minute >0) && (second == 0) {
minute = minute - 1;
second = 59;
}

Answer 1

The same was you would do it in any C/C++/Objective-C compiler, and most Algol derived languages, and extra set of parenthesis in order to turn to seperate boolean statements and an operator into a single compound statement:

if ((minute > 0) && (second == 0)) {
  minute = minute - 1;
  second = 59;
}
