ios - Cannot get correct UIColor in rectangle -


all,

i have piece of code : 

- (void)drawrect:(cgrect)rect {     cgcontextref context = uigraphicsgetcurrentcontext();     cgcontextsetfillcolorwithcolor(context, [uicolor redcolor].cgcolor);     cgcontextfillrect(context, cgrectmake(0, 440, 320, 30));

and call : 

_rectangeview = [[popuprectangle alloc] initwithframe:cgrectmake(0, 538, 320, 30)];

but black!

anyone advice why ?

change colouring rect this...

cgcontextfillrect(context, cgrectmake(0, 0, 320, 30));

use 0, 0 origins not 0, 440.

that should work.

inside drawrect dealing in vector space of view not superview. 0, 0 top left of rectangleview.
