You'd want to find a Mockup tool that supports exporting projects as Xcode projects. It doesn't appear that either of those products do that.
This one claims to support it, but I have no idea if it works: http://interface2.lesscode.co.nz
Honestly I wouldn't recommend putting too much time into this because I don't think the results would be good. If you want to turn a mockup into an app you should hire a developer.
