I use UIPickerView in a somewhat unorthodox way, allowing users to select a series of images (in this case, the words are in the background, but they just might be images):

In iOS6, this worked fine, but with iOS7, as you can see, the edges of the images disappear to white, which makes control unavailable for this purpose.
My question is
a) Will there be a way to βfixβ this and still use the UIPickerView control? If so, what approach can be taken?
b) If I cannot change the views to fix the problem, can a practical alternative use three UIScrollViews to replicate this function?
c) , UIPickerView, , , . , ... , .
