Hi gun,

The rotationAngle property of TKChartPieSeries contains the angle to which the pie is currently rotated. The selectionAngle is the angle where the selected pie slice will be located.  There is no specific event that  is called when rotating the chart, however you can use the chart:didSelectPoint:inSeries:atIndex: method that is called when a pie slice is selected:

- (void)chart:(TKChart *)chart didSelectPoint:(id<TKChartData>)point inSeries:(TKChartSeries *)series atIndex:(NSInteger)index
{
    NSLog(@"selected");
}
