Alert View with Prompt

Here's another generic class for you. This one doesn't require a navigation app - it can be used pretty much anywhere. It's a custom-subclass of UIAlertView that lets the user type in a value. It supports only two buttons - Okay and Cancel - but it handles everything to do with the text field for you. It looks like this:

Apologies - the previous code snippet only works with major iOS version numbers < 10; here's a version for the ages...
