Static counter to be repeatedly incremented by NSTimer

Question

Every 1/16 of a second, I have an NSTimer that fires, calling a method each time. I want to create a static integer that is increased by '1' each time the method is called, once the static integer is equal to '16', I wish to call another method and reset the static integer to '0'.

Any insight is greatly appreciated. (Language is Obj-C)

Answer 1

So declare it as a static int...

static int myCounter;
@implementation SomeClass

- (id) init {
  if (self = [super init]) {
    myCounter = 0;
    NSTimer * someTimer = [NSTimer scheduledTimerWithTimeInterval:(1/16) target:self selector:@selector(fireTimer:) userInfo:nil repeats:YES];
  }
  return self;
}

- (void) fireTimer:(NSTimer *)aTimer {
  myCounter++;
  if (myCounter == 16) {
    [self doSomeMethod];
    myCounter = 0;
  }
}
