Long form in dialog for iOS iphone?

My current project is to translate an existing Android gingerbread style app design to an iOS7 iPhone design.

The Android app utilizes various dialogs (such as the one here) with embedded forms. These are not forms within new views but forms within modals.

Some of these forms can be long and require a user scroll (and scrollbar) to view the entire form. In addition they lock user interaction down to the modal unless a CANCEL or valid SUBMIT.

The Android implementation is not ideal from a UX perspective, as it does not adhere to iOS Master/Detail navigational model. However, I may be stuck with this pattern and I'm interested in the feasibility of it's execution in iOS. Can these iOS alert dialogs (or something comparable) handle long forms? What if any experience/tips could you share in building an experience using this pattern?
