why does this custom UIView code not display the UILabel's? - iphone

Question

I'm kinda stuck trying to see why, when I use this custom UIView to show a row of 3 x UILabels, that whilst I see the outline in RED for the frame, I don't see anything inside the frame. That is the labels don't appear, nor does the black border for the UILabels which I've set.
Can anyone spot an issue here?

You don't seem to be adding the UILabels as subviews.
