Question

I have an UIPickerView with 2 components.
I would like to save the user’s selection for the components.
How can I do that?
I have tried with NSUserDefaults but it didn’t help.

Thanks!

I’m used didSelectRow. I’m create UILabel and whrite text from picker there. array1, array2 – NSMutableArray with text from components.

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    selection[component] = row;
        [self updateText];
}

-(void)updateText 
{
label.text = [ NSString stringWithFormat:@"%@%@ g/L", [array1 objectAtIndex:selection[0]], [array2 objectAtIndex:selection[1]] ];
}
