iOS does not require the user to accept all permissions that an app wishes to use, before installing that app. On iOS, you install an app without giving it permission to much, initially, and then the app, when you start it, starts asking for permissions that it needs, as it needs them. You can deny any permission request, and the app still works.
Eg. you can install the Facebook app, and deny it access to read your contact list.
In Android, about 150.
There is no mapping 1:1. Some things iOS does not allow at all (wifi information, sd card access). Some things iOS allows by default, with no way to deny it (internet access).
The iOS approach would not scale, the user would be burried under confirmation dialogs. And that's just the initial confirmation, there has to be UI, when he changes his mind later.
Those, who claim that iOS approach is superior are showing their ignorance, that they newer thought about the way, how the user would set matrix of this amount of permissions with many apps, without getting lost (hint: many are getting lost just in the current system. Imagine, that they would be able to toggle anything. And imagine, what the developers would say about that).
