I\'ve written an app that requests access to the iPad\'s calendar. Under iOS 6, a system dialog appears that asks the user if that\'s okay.
Problem is, I can\'t repl
Settings > General > Reset > Reset Location and Privacy
You can Reset Location and Privacy as suggested by Greg Maletic but if you do not want to reset all your apps, you can just change the bundle identifier of your app.
On iOS 10.2.1:
I simply uninstall and reinstall the app again, the permission dialog appeared again.
On iOS 9 and later version,uninstall and install the app,access permission dialog will appeared. But iOS 8 will remember what you choose.
