RGCircularSlider

To use this control with interface builder you just need to drop RGCircularSlider in for the class of the view in the storyboard of .xib file. You can also use initWithFrame: . To get the value of degree and the state of the button(play or pause) you need to implement the RGCircularSliderDelegate Protocol .

(void)currentDegree:(NSInteger)degree; (void)onPlay:(BOOL)state; 0 ≤ degree ≤ 360 and state is YES when you see the "play button" and NO when you see the "pause button".

Note: to make this control look good the width and heigh of the view should be equal since we want a circle.
