Question

[NSTimer scheduledTimerWithTimeInterval:0.033 target:self selector:@selector(gameLoop)
     userInfo:nil repeats:YES];

I don’t do anything to dealloc or kill this timer after starting it.
Is it safe? Or will it cause me to leak memory?

Answer 1

It shouldn’t leak memory. You’re not retaining the timer. The run loop will retain it (I think), but it’ll release it when it no longer needs it.
