In my application I am accessing phone contact of iPhone so it will ask first time to allow access,but if user will click on "Don't allow" than application will not be able to access phone contact.
I know that in iOS 6.0 there is a option of privacy in setting where I can give permission to access phone contact to my application.
But I couldn't find this kind of tab or setting in iOS 5 or lower,Please inform me where can I give permission to my application to access phone contacts. -Thanks in advance
In fact, this permission level is introduced in ios6. This one you can't find iOS5. And in iOS6 if user gave Don't Allow at first time, you can change that settings from the Settings App in the iOS.
Privacy Settings To find your privacy settings, just tap the Settings app to launch it and then scroll down to Privacy. Tap it.
On the privacy screen, you'll see the elements of your iPhone that contain personal information that apps can gain access to. (like Location Services,Contacts,Calendars and Reminders,Photos). From here you can change the access level.
Hope this helps.
