Apple already locked down app access to personal data (like contacts) in iOS 6. In iOS 7 they are just going further (eg. now a dialog also pops up for access to camera and mic)

The main difference is that Android has this all-or-nothing approach (accept giving the app all these permissions, or don't use the app at all), while iOS asks you for each permission individually, and you can use an app without granting it specific permissions. (eg. the weather app -- disallow access to location, and you can still type in place names manually)
