ios - How to draw a disk with a number/string inside? -


i draw this: enter image description here

so far know how draw disk, use method:

func drawdisk(color: uicolor, rectfordisk: cgrect = cgrectmake(0.0, 0.0, 1.0, 1.0), withstroke: bool) -> uiimage {     uigraphicsbeginimagecontextwithoptions(rectfordisk.size, false, 0.0)     let context = uigraphicsgetcurrentcontext()      cgcontextsetfillcolorwithcolor(context, color.cgcolor)     cgcontextfillellipseinrect(context, rectfordisk)      let rectforcircle = cgrectmake(0.5, 0.5, rectfordisk.size.width - 1, rectfordisk.size.height - 1)     cgcontextsetlinewidth(context, withstroke ? 1.0 : 0)     cgcontextsetstrokecolorwithcolor(context,         uicolor.blackcolor().cgcolor)     cgcontextaddellipseinrect(context, rectforcircle)     cgcontextstrokepath(context)      let image = uigraphicsgetimagefromcurrentimagecontext()     uigraphicsendimagecontext()      return image }

what don't know add text in drawing. i'm not sure it's possible. thought adding label on top of wondering if there better/proper way.

a simple way you're after use label, on own, , set corner radius of layer , set background colour. set layer clip. if choose corner radius correctly can have circular label , grow oblong bubble if required text contains.
