UIButton won't go to Aspect Fit in iPhone

Question

UIView content modes apply to the corresponding CALayer's "content". This works for UIImageViews because they set the CALayer content to the corresponding CGImage.

drawRect: ultimately renders to the layer content.

A custom UIButton (as far as I know) has no content (the rounded-rect style buttons might be rendered using content). The button has subviews: the background UIImageView, the image UIImageView, and the title UILabel. Setting the contentMode on the subviews may do what you want, but messing around with the UIButton view hierarchy is a bit of a no-no.
