ios - Change UIButton BG color on highlighted, but preserve layer corner radius? -

-

i’m changing background colour of uibutton via category method, using 1px 1px image:

- (void)setbackgroundcolor:(uicolor *)backgroundcolor forstate:(uicontrolstate)state {     uigraphicsbeginimagecontextwithoptions(cgsizemake(1, 1), no, 0);     [backgroundcolor setfill];     cgcontextfillrect(uigraphicsgetcurrentcontext(), cgrectmake(0, 0, 1, 1));     uiimage *backgroundimage = uigraphicsgetimagefromcurrentimagecontext();     [self setbackgroundimage:backgroundimage forstate:state];     uigraphicsendimagecontext(); }

however, overrides setting of .layer.cornerradius. need button rounded corners, 1 background colour can change on highlighted.

any way around this? corner radius needs dynamic.

so, had ensure button.layer.maskstobounds turned on. problem solved, no subclassing required.
