  • Configurable in interface builder (IBInspectable)


Basic chart:

@property (weak) IBOutlet NRSPieChartView          *pieChartView;

#pragma mark - PieChartViewDataSource

- (NSUInteger) numberOfMajorSlicesInPieChartView:(NRSPieChartView *)pieCharView {
return 10; // Total number of major slices

- (NSUInteger) numberOfMinorSlicesInPieChartView:(NRSPieChartView *)pieCharView forMajorSlice:(NSUInteger)majorSlice {
return 1; // Number of minor slices per major slice

- (CGColorRef) pieChartColorForSlice:(NRSPieChartView *)pieChartView sliceIndex:(NRSPieChartViewSliceIndex * _Nonnull)sliceIndex {

return [UIColor redColor] CGColor]; // Return the color for the given major.minor slice

- (NRSPieChartViewEndPoints *) pieChartEndPointsForSlice:(NRSPieChartView *)pieChartView sliceIndex:(NRSPieChartViewSliceIndex * _Nonnull)sliceIndex {
return [[NRSPieChartViewEndPoints alloc] initWithStart:(10 + 0.05)  end:(30 - 0.05)];j // Return an "End Point", based on 0...100 range. 0 corresponds to 12 o'clock position in chart

- (BOOL)pieChartShouldHighlightSlice:(NRSPieChartView *)pieChartView sliceIndex:(NRSPieChartViewSliceIndex *)sliceIndex {
return NO; // return if given slice should be highlighted. Highlighted slices are displayed with extend width

#pragma mark - PieChartViewDelegate

- (void)pieChartDidSingleTapSlice:(NRSPieChartView *)pieChartView sliceIndex:(NRSPieChartViewSliceIndex *)sliceIndex {
// called on single tap of chart. Example, can capture selection here and use that highlight the tapped slice. NOTE: remember to refresh pieChart in order to show the highlighted slice.
[pieChartView refreshSlices];

    "summary": "A PieChart control that supports slice animations, and interactions.",
    "description": "NRSPieChart is a UIView subclass that presents a customizable PieChart graph. The class will render smooth animations of PieChart slices and colors when the data model changes and the PieChart is refreshed. The data model and delegate have similar semantics to that of a UITableView or UICollectionView. NRSPieChart attributes are IBInspectable, so they can easily be configured directly in Interface Builder.",
