iOS, web services, and backend.
When you redesign an iOS app is it necessary to rebuild the web services and backend?

It totally depends. When you say "redesign", what do you mean? Just the user interface? Workflow? Data?
If your backend is returning data in a specific format, then you can redesign your UI to still meet the contracts of those backend services. But if you want additional data then you might also need to redesign your backend. In an ideal situation the everything is architected so that each component can be updated without affecting the others. That's a result of having clean interfaces and contracts.
If you have specific details then perhaps the forum members can give you a more detailed answer.
