Invalid context error on iOS 7 when adding a UIPickerView inside a UIActionSheet?

Question

I have an UIPickerView inside an UIActionSheet and have done that in a way suggested by many others here at SO:

Add UIPickerView & a Button in Action sheet - How

Answer 1

As the comments above point out, the UIActionSheet is not designed to be subclassed or take other views.

More info here at Apple:

One approach is to look closer at the DateCell sample code and change that to use an UIPickerView instead:
