For an iPhone application I want to draw a circle, that is only for an x percentage filled.
Something like this:
I have no problems calculating the radius, the degrees or the radians, that is no problem. Also drawing the circle is already done. But how do I get the iPhone SDK to draw the part that is filled.
I can draw a rectangle that size, but not part of a circle.
I just want to draw that on a a normal context.
Hope someone can give me any pointers here.
