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

Instead of component I found using tag more proper.

Then in the code:

// returns the # of rows in each component..
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
    //NSLog(@"Component_1: %d",pickerView.tag);
    if (pickerView.tag == 1)
        return [self.arrOpponentTeams count];
    else if (pickerView.tag == 2)
        return [self.arrMyTeams count];
    else
        return [self.arrPlayers count];
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
    //NSLog(@"Component_2: %d",pickerView.tag);
    if( pickerView.tag == 1 )
        return [self.arrOpponentTeams objectAtIndex:row];
    else if (pickerView.tag == 2)
        return [self.arrMyTeams objectAtIndex:row];
    else
        return [self.arrPlayers objectAtIndex:row];
}
