Question

More generally how do you search a UIViewDelegate for UI elements?

Right now, I’d like to count the number of UITextFields in my current view to populate the correct number of UILabels in other views.

Answer 1

- (NSInteger)textFieldCountInsideView:(UIView *)parentView
{
    NSInteger count = 0;
    for (UIView *subview in parentView.subviews) {
        if ([subview isKindOfClass:[UITextField class]])
            count = count + [self textFieldCountInsideView:subview];
    }
    return count;
}

And somewhere in your UIViewController:

NSInteger count = [self textFieldCountInsideView:self.view];
