如果我有你的想法，你需要在指數路徑選擇行

- (void)pieChart:(XYPieChart *)pieChart didSelectSliceAtIndex:(NSUInteger)index 
{ 
    // get indexPath with index 
    // remember if you have few sections then you will need to update inSection:0 value 
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:index inSection:0]; 

    [yourTableView selectRowAtIndexPath:indexPath 
           animated:NO 
         scrollPosition:UITableViewScrollPositionNone]; 

    // This will also Highlighted the row. Then delegate 
    [yourTableView.delegate someTableView didSelectRowAtIndexPath:indexPath]; 
}
