You don't want the tapCount, you want the number of touches. If you touch down with two fingers you can two touch events each with a tap count of 1.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

[touches count] would return 2, one for each finger tip.

Read through the apple guide for touch events
