Question

I have to draw a countdown timer circle, I m using this open source library. Requirement are such that circle is filled with green and disappear in x seconds. I have given back circle green color and drawing a white circle on it and green circle looks like that it is disappearing.

self.circularTimer.trackTintColor = [UIColor greenColor];
self.circularTimer.progressTintColor = [UIColor whiteColor];
self.circularTimer.thicknessRatio = 5.0f;
[self startAnimation];

Everything is running fine but there is a small problem, circle border is visible. As back circle is little bigger than the top white circle.

Answer 1

Go to your DACircularProgressView.m in function – (void)drawInContext:(CGContextRef)context and under this line

CGFloat radius = MIN(rect.size.height, rect.size.width) / 2;

insert this line

CGFloat radiusTint= MIN(rect.size.height, rect.size.width) / 2.1;

and replace line with

CGPathAddArc(trackPath, NULL, centerPoint.x, centerPoint.y, radius, 3 * M_PI_2, -M_PI_2, NO);

this line

CGPathAddArc(trackPath, NULL, centerPoint.x, centerPoint.y, radiusTint, 3 * M_PI_2, -M_PI_2, NO);
