How do I add multiple components to a PickerView?

Question

It may be a simple question but how do I add multiple components to a UIPickerView? I use NSMutableArray to populate one component but I dont know how to populate the others

Answer 1

I do not know if it's a little late But I solved this another way Array are a bit rudimentary But it works wonders You can even put different color to each array

- (void) viewDidLoad {
  horPickerArray = @[@"00",@"01",@"02",@"03",@"04",@"05".to..24];
  minPickerArray = @[@"00",@"01",@"02",@"03",@"04",@"05".to..59];
  secPickerArray = @[@"00",@"01",@"02",@"03",@"04",@"05".to..59];
}

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
{
return 3;   
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
if (component == 0) {
        return _HorPickerArray.count ;
    }
    else if (component == 1) {
        return _MinPickerArray.count ;
    }
    else if (component == 2) {
        return _SecPickerArray.count ;
    }
}

 - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
if (component == 0) {
        return [_HorPickerArray objectAtIndex:row];
    }
    else if (component == 1) {
        return [_MinPickerArray objectAtIndex:row];
    }
    else if (component == 2) {
        return [_SecPickerArray objectAtIndex:row];
    }
    return nil;

}

And Print in TextField

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

    _OficialTime.text  =[NSString stringWithFormat: @"%@:%@:%@",    [_HorPickerArray objectAtIndex:[_TimerPiker selectedRowInComponent:0]],[_MinPickerArray objectAtIndex:[_TimerPiker selectedRowInComponent:1]],  [_SecPickerArray objectAtIndex:[_TimerPiker selectedRowInComponent:2]]]; 
}
