Add additional data to tooltip in iOS which does n

I followed this demo to draw Column charts. (https://www.highcharts.com/ios/demo/column-rotated-labels).

What Issue I am facing is : I can easily show x-axis and y-axis information in tooltip. But I am not able to put additional information in tooltip from a different array (suppose array for depicting required qty for item).

I tried to do like this ;

tooltip.pointFormat = [NSString stringWithFormat:@"Velocity : {point.y:.2f} Remaining Quantity : %@",RemainingQtyArray]; It will print whole array in tooltip. tooltip.pointFormat = [NSString stringWithFormat:@"Velocity : {point.y:.2f} Remaining Quantity : %@",RemainingQtyArray[i++]]; It will print last item from array. So, how can i put additional info so that when anyone taps on graph, it will show this info too.

Want tooltip like this.

Check this Fiddle demo in JS

Tooltip in JS way

 tooltip: {
        pointFormat: 'Population in 2017: <b>{point.y:.1f} millions</b><br>Extra One: <b>{point.data1}</b><br>Extra Two: <b>{point.data2}</b>'
    },

Series data in JS way

data: [
        {name:'Shanghai', y:24.2,data1:'Aa',data2:'Ba'},
        {name:'Beijing', y:20.2,data1:'Ab',data2:'Bb'},
        {name:'Karachi', y:14.2,data1:'Ac',data2:'Bc'},
        {name:'Shenzhen', y:13.2,data1:'Ad',data2:'Bd'},
    ],

Through doc I convert into ios.

For ios

HITooltip *tooltip = [[HITooltip alloc]init];
tooltip.pointFormat = @"Population in 2017: <b>{point.y:.1f} millions</b><br>Extra One: {point.data1}<br>Extra Two: {point.data2}";

For ios series data

column.data = [NSMutableArray arrayWithObjects:
                    @{
                      @"name":@"Shanghai",
                      @"y":@23.7,
                      @"data1":@'Aa',
                      @"data2":@'Ba'
                     },
                   @{
                      @"name":@"Shanghai",
                      @"y":@16.1,
                      @"data1":@'Aa',
                      @"data2":@'Ba'
                     },
                   @{
                      @"name":@"Karachi",
                      @"y":@14.2,
                      @"data1":@'Aa',
                      @"data2":@'Ba'
                     },
                   @{
                      @"name":@"Shenzhen",
                      @"y":@14,
                      @"data1":@'Aa',
                      @"data2":@'Ba'
                     }
                   , nil];
