Get Color for Pie Chart Segment

[Sal]

Is there a way to get the color used for each segment of a pie chart? I wanted to use a TableView for the index (because I needed a more in-depth legend and some other items) but I also wanted to make sure that each cell had the same color as the segment from the Pie Chart just not sure if there is a way to get the color for each segment. I know I can pass my own colors to the Pie Chart and use them for the Table but I wanted to use the built in colors for the chart as well.

Hello Sal,

You can get the current color configuration of your pie chart through the style property of your series. 
Please, consider the following code.

TKChartPalette *palette = series.style.palette;
NSMutableArray *colorArray = [NSMutableArray new];
for (int i = 0; i < palette.itemsCount; i++) {
    TKChartPaletteItem *item = [palette paletteItemAtIndex:i];
    [colorArray addObject:item.fill];
}

Now in the colorArray you have all fills (instances of TKSolidFill by default) used for the drawing of the current series.

If you have any other questions, do not hesitate to contact us.

Thanks, that's what I needed but now is there a way to get the UIColor or CGColor from a TKFill? I would need one of those to update the color of a UIView. Thanks.

Actually I was able to get the UIColor from the TKStroke instead of the TKFill, not sure if there is a way to get the Fill color as well but since the TKStroke has it I just used it from there for now. Thanks.

Hi Sal,
Since all the default colors from the pie chart are represented as TKSolidFill instances. You can use the color property of TKSolidFill to access the used UIColor.

UIColor *usedColor = [fill color];

Hope this will get the job done.
