According to the documentation fire
"Causes the receiver’s message to be sent to its target." Which is why it's firing instantly.
Your timer is also not scheduled, so it would never fire on it's own.
Create your timer like this instead, which creates a timer, and schedules it in a single statement.
timer = [NSTimer scheduledTimerWithTimeInterval:1.0
target:self
selector:@selector(dealCard)
userInfo:nil
repeats:NO];
And remove the [timer fire]
line completely, as it will fire itself after it's time interval is up.
