Why doesn't attributedTitleForRow get called with a UIPickerView?

Question

As per the documentation, picker views prefer to use attributedTitleForRow over titleForRow. If the preferred returns nil, the picker view falls back to titleForRow.

I'm implementing both methods, and attributedTitleForRow never gets called. Even when titleForRow returns nil, and attributedTitleForRow returns an NSAttributedString, it doesn't get called. However, titleForRow always gets called.

Here's what I have:

- (NSString *)pickerView:(UIPickerView *)pickerView
             titleForRow:(NSInteger)row
            forComponent:(NSInteger)component {
    return @"Hello";
}

- (NSAttributedString *)pickerView:(UIPickerView *)pickerView
             attributedTitleForRow:(NSInteger)row
                      forComponent:(NSInteger)component {
    return [[NSAttributedString alloc] initWithString:@"World"];
}

If you implement only pickerView(_:attributedTitleForRow:forComponent:) , then is it called? — 3stud1ant3, Aug 25 '17 at 16:18

@user1000 Nope, still not called, but viewForRow is - looks like I'm going to have to go that way. — ArielSD, Aug 25 '17 at 18:37

I didn't see that the viewForRow delegate method was also called. If this method is called, neither titleForRow nor attributedTitleForRow will run.
