Having trouble changing wedge color #1

Closed latne1ec closed 7 years ago

Thanks for the lib! You're saving me a ton of time.

I've tried setting the wedge background color directly in wedgeForSliceAtIndex but it isn't working

How do you modify the color of each wedge?

Thanks for trying it out. It's still in it's early stages so I hope you can make use of it. I love to get your feedback.

First of all, make sure you are using the newest version, v0.1.5. I just updated it yesterday and adjusted some issues with customizing wedge shapes and labels.

What I've done in my practice apps is to create an array of colors like so: let colorPalette: [UIColor] = [UIColor.blue, UIColor.brown, UIColor.cyan, UIColor.darkGray, UIColor.green, UIColor.magenta, UIColor.red, UIColor.orange, UIColor.black, UIColor.gray, UIColor.lightGray, UIColor.purple, UIColor.yellow, UIColor.white]

Then in wedgeForSliceAtIndex, setting the color like so: let wedge = SpinWheelWedge()
wedge.shape.fillColor = colorPalette[Int(index)].cgColor

You can also set the wedge's label like so: wedge.label.text = "Label #" + String(index)

Then close out the function by returning the wedge: return wedge

Hope this helps. I'll try to get an example app uploaded in the near future.
