ISHPermissionKit – GitHub
ISHPermissionKit provides a polite and unified way of asking for permission on iOS. It also provides UI to explain the permission requirements before presenting the system permission dialog to the user. This allows the developer to postpone the system dialog. The framework provides no actual chrome, leaving the developer and designer in charge of creating the views.
PermissionScope – GitHub
Inspired by (but unrelated to) Periscope‘s permission control, PermissionScope is a Swift framework for intelligently requesting permissions from users. It contains not only a simple UI to request permissions but also a unified permissions API that can tell you the status of any given system permission or easily request them.
