I am so sorry I meant to say TKSolidFill.
I am sorry for that.
But still the problem is the same, I try this:
needle.fill = [TKSolidFill solidFillWithColor:[UIColor colorWithRed:17 green:31 blue:78 alpha:1.0]];
And my needle turns White instead of the dark blue I was hoping to see from this RGB color.
I appreciate your attention. Thank you!
