How to set different values for data and legend entries

I'm trying to set different values for dataset entry and legend entry, but it does not work.

Need:
PieChartDataEntry: number
ChartLegendEntry: text

Extra:
Also, I can not find how to swap position of percentages and value labels?
How to hide the number and percent value in a small slice?

Thank you in advance!


for (int i = 0; i < parties.count; i++) {

float value = (arc4random_uniform(mult) + mult / 5);
[values addObject:[[PieChartDataEntry alloc] initWithValue:value
label:[NSString stringWithFormat:@"%.0f", value]]];

ChartLegendEntry *entry = [[ChartLegendEntry alloc] init];
entry.label = parties[i];
[legendEntries addObject:entry];
}

_pieChartView.legend.entries = legendEntries;


PieChartDataSet *dataSet = [[PieChartDataSet alloc] initWithValues:values label:@""];

dataSet.colors = colors;

PieChartData *data = [[PieChartData alloc] initWithDataSet:dataSet];
