Any Way To Display 1/2 Instead of .5 In UIPickerView?

pickerArray = [[NSMutableArray alloc] initWithCapacity:700];

for ( float i = 0.0 ; i <= 1000.0 ; i = i + 2.5)

{

    //[pickerArray addObject:[NSString stringWithFormat:@"%.1f", i]]

    [pickerArray addObject:[NSNumber numberWithFloat:i];

}

 

float weight = [[pickerArray objectAtIndex:row] floatValue];

label.text = [NSString stringWithFormat:@"%.1f", weight];

       

NSMutableArray *array = [[NSMutableArray alloc] init];

for (int i=0;i<100;i++) {

    float value = (float)i*2.5;

    if (i % 2) {

        [array addObject:[NSString stringWithFormat:@"%d %@",(int)value,@"1/2"]];

    } else {

        [array addObject:[NSString stringWithFormat:@"%d",(int)value]];

    }

}

       

"0", "2 1/2", "5", "7 1/2", "10", "12 1/2", "15", "17 1/2", "20", "22 1/2", "25", "27 1/2", "30", "32 1/2", "35", "37 1/2", "40", and more

       

label.text = [array objectAtIndex:row];
