 - (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

I am trying to change the selected Picked Value Color from UIPickerView

I am trying to change it but its not effected perfectly its changing other values below the selected value.

This is incorrect. You should reload the selected component. Then you need to fetch the selected row and update its color in viewForRow:forComponent:. Something like-

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

        //On Selecting the component row
        if (component == 0) {

        } else if (component == 1) {

            [quantityPickerDelegate didChangeLabelText:[pickerArray objectAtIndex:row]];// delegate passing the selected value
            [pickerView reloadComponent:component]; //This will cause your viewForComp to hit
        }
    }

- (UIView *)viewForRow:(NSInteger)row forComponent:(NSInteger)component
{
     //...
     //Your usual code
      pickerLabel.textColor = defaultColor;

     if([self.pickerView selectedRowInComponent:component] == row) //this is the selected one, change its color
     {
            pickerLabel.textColor = [UIColor colorWithRed:0.0745 green:0.357 blue:1.0 alpha:1];
     } 
}
