You have to ask user whether your application can access your Address book. This feature is implemented in iOS 6.0 and above.
You Can try this code Snippet:
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
in - viewWillAppear:
// Asking access of AddressBook
// if in iOS 6
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0"))
{
// Request authorization to Address Book
addressBook_ = ABAddressBookCreateWithOptions(NULL, NULL);
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined)
{
ABAddressBookRequestAccessWithCompletion(addressBook_, ^(bool granted, CFErrorRef error)
{
if (granted == NO)
{
// Show an alert for no contact Access
}
});
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized)
{
// The user has previously given access, good to go
}
else
{
// The user has previously denied access
// Send an alert telling user to change privacy setting in settings app
}
}
else // For iOS <= 5
{
// just get the contacts directly
addressBook_ = ABAddressBookCreate();
}
