Word wrap in UIPickerView

I have a UIPickerView, and I would like to make the text word wrap.

Here is my code:

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
    if (component == 0) {
    UILabel *lView = (UILabel *)view;

    if (!tView) {
        tView = [[UILabel alloc] init];
        [tView setFont:[UIFont systemFontOfSize:15]];
        tView.numberOfLines = [categorie count];
    }
    tView.text = [categorie objectAtIndex:row];
    return tView;
    }
    else {
        UILabel *lView = (UILabel *)view;

        if (!sView) {
            sView = [[UILabel alloc] init];
            [sView setFont:[UIFont systemFontOfSize:15]];
            sView.numberOfLines = [subCat count];
        }
        sView.text = [subCat objectAtIndex:row];
        return sView;
    }
}

I tried setting sView.numberOfLines = 0; (which is how you would normally set a UILabel to word wrap, or have more than 1 line) but that didn't work.
