Android Pattern Lock on iPhone | iPhone and iPad development |

The idea is simple. Rather than entering 4 digit PIN, you connect the 9-dots (3 by 3) presented on the screen to form a secret pattern. The number of dots connected to form a pattern can be as many as the available dots on screen. In the case of Android lock, the max is 9 dots and the min is 4 dots. In my 3 weeks of usage, I think I can unlock faster using pattern lock versus using PIN lock. And that's when I started to wonder why in all the apps that I've ever used on iPhone, none of them provides this type of lock.
