Unable to set strings as values in x axis of linechart

[akshaynexus]

Here is my project: https://github.com/akshaynexus/CryptoEye-iOS
so i implemented your chart lib successfully,but when i need to use a array that contains strings that should be used in the xAxis vales,i tried using [ChartIndexAxisValueFormatter withValues:array];,it just results in no values for x axis,the array "array" does contain strings.

`LineChartView *linechart =[[LineChartView alloc] initWithFrame:self.refView4Chart.frame];

LineChartDataSet *dataset = (LineChartDataSet *)linechart.data.dataSets[0];
dataset = [[LineChartDataSet alloc] initWithValues:values label:@"DataSet 1"];
dataset.values = values;
dataset.drawValuesEnabled = FALSE;
dataset.drawCirclesEnabled = FALSE;
dataset.fillColor = [UIColor greenColor];
dataset.highlightColor = [UIColor whiteColor];
linechart.noDataTextColor = [UIColor whiteColor];
[dataset setColor:[UIColor greenColor]];
linechart.xAxis.labelPosition = XAxisLabelPositionBottom;
linechart.xAxis.labelTextColor = [UIColor whiteColor];
linechart.leftAxis.labelTextColor = [UIColor whiteColor];
[linechart.rightAxis setEnabled:NO];
NSMutableArray *dataSets = [[NSMutableArray alloc] init];
[dataSets addObject:dataset];
            NSMutableArray *array = [[NSMutableArray alloc] init];
//            array = time4graph;
//            for (NSMutableArray *tempObject in price4rmapi) {
//
//                [array addObject:[tempObject objectAtIndex:0]]];
//            }
            for (int index = 0; index <[time4graph count]; index++) {
                NSString *time = [NSString stringWithFormat:@"%@",[time4graph objectAtIndex:index]];
                double unixTimeStamp =[time doubleValue];
                NSTimeInterval timeInterval=unixTimeStamp/1000;
                NSDate *date = [NSDate dateWithTimeIntervalSince1970:timeInterval];
                NSDateFormatter *dateformatter=[[NSDateFormatter alloc]init];
                [dateformatter setLocale:[NSLocale currentLocale]];
                [dateformatter setDateFormat:@"dd-MM-yyyy"];
                NSString *dateString=[dateformatter stringFromDate:date];
                array[index] = [NSString stringWithFormat:@"%@",dateString] ;
            }

LineChartData *data = [[LineChartData alloc] initWithDataSets:dataSets];
[linechart.xAxis setLabelCount:array.count force:TRUE];
linechart.xAxis.valueFormatter = [ChartIndexAxisValueFormatter withValues:array];
linechart.xAxis.drawLabelsEnabled = TRUE;
linechart.data = data;
[self.view addSubview:linechart];`

I just checked the Demo projects and imported the obj c formatters to my project and fixed the issue.thanks
