animation - iOS - Pie progress bar with rounded corners -

i need implement progress bar according design :

as can see, there corner radius bar itself.

this how looks current code :

so, how that? current code:

- (void)animateprogressbartopercent:(float)percent {     if (percent > 1.0f) return;      int radius = 42.7f;     int strokewidth = 7.f;     cgcolorref color = [uicolor somecolor].cgcolor;     int timeinseconds = percent * 5;      cgfloat startangle = 0;     cgfloat endangle = percent;      cashapelayer *circle = [cashapelayer layer];     circle.path = [uibezierpath bezierpathwithroundedrect:cgrectmake(0, 0, 2.0*radius, 2.0*radius) cornerradius:radius].cgpath;     circle.position = cgpointmake(self.center.x - radius, self.center.y + strokewidth);     circle.fillcolor = [uicolor clearcolor].cgcolor;     circle.strokecolor = color;     circle.linewidth = strokewidth;     circle.strokeend = endangle;      [self.layer addsublayer:circle];      cabasicanimation *drawanimation = [cabasicanimation animationwithkeypath:@"strokeend"];     drawanimation.duration            = timeinseconds;     drawanimation.repeatcount         = 1.0;     drawanimation.removedoncompletion = no;      drawanimation.fromvalue = [nsnumber numberwithfloat:startangle];     drawanimation.tovalue   = [nsnumber numberwithfloat:endangle];      drawanimation.timingfunction = [camediatimingfunction functionwithname:kcamediatimingfunctioneaseineaseout];      [circle addanimation:drawanimation forkey:@"drawcircleanimation"]; } 

circle.linecap = kcalinecapround 

just set property of cashapelayer
