Couldn't know what slice it will land #1

HI, I really love your project. But there's still somethings I don't understand. Please show me.

  1. I'm using function startAnimating(fininshIndex:Int = 0, _ completion:((Bool) -> Void)?) but it didn;t land on right slice and landing on just same slice everytime
  2. How to customize where the needle is? I would like the need will be in the middle of wheel.

Thanks alot

Hello gauuni, Thanks for your feedback.

  1. By default the first index corresponds with the slice whose texts is written horizontally at 0 angle. The indexes of the slice will remain the same and do not change by rotating the wheel. So by calling open func startAnimating(finishIndex: completion) with the same index multiple times you will end up on the same slice every time.

  2. You can edit where the initial slice is drawn by setting initialDrawingOffset. If you want the needle to be in the middle of the wheel you have to offset the initial slice by 90 hence you have to set initialDrawingOffset to 90.0.

I’m appreciate that And one more thing. Could we make vertical text like this. The vertical one, not horizontal

Hi, We currently support only horizontal text but can add that in a future update. Please open another issue on this one. Thank you!
