I’m trying to set the background of a radial guage to clear, however setting gauge.style.innerBackgroundColor (and outerBackgroundColor) to [UIColor clearColor] produces a grey background.
Im trying to preserver the needle, knob, and axis (i.e., ticks and marks) while providing my own background image below the gauge, such that the all elements, other than the background image, are preserved. Cant seem to figure this one out,so any help or advice is appreciated!
I’ve been trying to hack around it by copying the CALayer, but its getting ugly. there has to be an easier way! Alternatively, if I cant change the backgroudn image, am I able to change the way in which the gradiant between innet and outer radius is applied? Id like the transition to start further out from the center.
