Add ability to add gradient colors for Circle gauge.

[skywinder]

It's subtask of #12.

I start working on it in gradientCircle branch, but implementation is not quite easy and still have issues.

Also - it looks not very well without overlapping (the border of startColor and endColor).
I want to find solution, that can fix this and #12 issue at once.

Hello Skywinder, I love your project. I also went into the same problem, but for time reason I used a masked image. It doesn't seem possible to create a circular gradient using CG, but you can fake it(somehow) thinking in small linear gradients, the idea has found proof of its possibility in that SO answer http://stackoverflow.com/questions/24751607/fill-circular-ring-with-gradient-color-according-to-percentage

@DrAma999 thanks for the link. I will take a look on this solution

Any solution yet? Subscribing to this.

Hi, @NickPappas. As you can see on screenshot - it does not looks well without overlaping. So, as soon as #12 closed - it will be easy not implement this feature also.

Hi, This guy made this class to draw gradients, maybe you can get in touch with him https://github.com/maxkonovalov/MKGradientView

@DrAma999 Thanks! 3rd gradient looks like what I want to get.
Actually I already implement it in gradientCircle branch. You can see it on screenshot above. I just need to implement infinite option for this circles. But thanks for the link! 👍

@sinanulkuatam let's continue #32 (comment) here:
As I said there is branch gradientCircle. I'm not work in this direction last time in case of lack of time. But I you know how to implement it right - I would be glad to review PR 😉

Check it out :) #35

@sinanku how did u get the circular view to work like that?

[sinanku]

@saiidabs originally I made @IBInspectables to change gradient properties, after I just made it so that you defined a start color and end color that was already a part of the library. You can download my fork and run the example project, it should help get you on the right track.

already implemented in latest versions
