Pendulum balls inspired by Jordi Verdu.
The color and diameter of the pendulum balls are customizable, and it will start animating once it shows up in the view.
It could be used as an indicator of an empty loading page, or just for fun.
Usage
PendulumView *pendulum = [[PendulumView alloc] initWithFrame:self.view.bounds ballColor:ballColor ballDiameter:12];
[self.view addSubview:pendulum];
