iOS if statement for each shake?

[dbramhall]

I was wondering how to implement an if statement that counts the amount of shakes and runs some code, see below...

if (SHAKECOUNTTHING == 1) { // First shake
NSLog(@"Shake 1");
}
else if (SHAKECOUNTTHING == 2) { // Second shake
NSLog(@"Shake 2");
}
else if (SHAKECOUNTTHING == 3) { // Third shake
NSLog(@"Shake 3");
}

I'm not sure how to go about this and what to swap SHAKECOUNTTHING with. Thanks a lot!
