ios - IB_DESIGNABLE tintColor issues -

i'm getting ib_designable, , i've stumbled on issue.

when set tintcolor of custom view ib, rendered in right way in ib.

but when run on device displayed default tintcolor.

#pragma mark - uiview  - (void)drawrect:(cgrect)rect {     [self drawcircleradius:min(rect.size.width / 2, rect.size.height / 2) - self.linewidth / 2.f                       rect:rect                 startangle:self.startangleradians                   endangle:self.endangleradians                  linewidth:self.linewidth]; }  #pragma mark - private methods  - (void)drawcircleradius:(cgfloat)radius                     rect:(cgrect)rect               startangle:(cgfloat)startangle                 endangle:(cgfloat)endangel                linewidth:(cgfloat)linewidth {     uibezierpath* bezierpath = [uibezierpath bezierpath];     [self.tintcolor setstroke];     [bezierpath addarcwithcenter:cgpointmake(rect.size.width / 2, rect.size.height / 2)                           radius:radius                       startangle:startangle                         endangle:endangel                        clockwise:yes];      bezierpath.linewidth = linewidth;     [bezierpath stroke]; } 

what difference? why displayed default tint color in device, , correctly displayed in ib?

update:

#import <uikit/uikit.h>  ib_designable @interface pkcircleview : uiview  @property (nonatomic, assign) ibinspectable cgfloat startangleradians; @property (nonatomic, assign) ibinspectable cgfloat endangleradians; @property (nonatomic, assign) ibinspectable cgfloat linewidth;  @end 

the issue on line

 self.tintcolor = [uicolor defaultdwonloadbuttonbluecolor]; 

:

static pkcircleview *commoninit(pkcircleview *self) {     if (self != nil) {         self.backgroundcolor = [uicolor clearcolor];         self.startangleradians = m_pi * 1.5;         self.endangleradians = self.startangleradians + (m_pi * 2);         self.linewidth = 1.f;         self.tintcolor = [uicolor defaultdwonloadbuttonbluecolor];     }     return self; }  @implementation pkcircleview  #pragma mark - initialization  - (id)initwithcoder:(nscoder *)decoder {     return commoninit([super initwithcoder:decoder]); }  - (instancetype)initwithframe:(cgrect)frame {     return commoninit([super initwithframe:frame]); } 

it seems settintcolor ib called before init... methods.
