hey you want those value to specify Alert which is true in case (Switch) am i right.. — Narendra Pandey, Jul 22 '16 at 07:54
UIAlertAction* defaultAction; You can specify this and every when your value changes in the case set defaultAction — Narendra Pandey, Jul 22 '16 at 07:57

-(void)alert
{
    UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                                                                   message:@"This is an alert."
                                                            preferredStyle:UIAlertControllerStyleAlert];
    if (buttonIndex)
    {
        switch (alertView.tag)
        {
            case kAccessAddressBook:
            {


                defaultAction = [UIAlertAction actionWithTitle:[self displayFindFriendView:[NSNumber numberWithInteger: CS_CONTACTS ]]; style:UIAlertActionStyleDefault
                                                       handler:^(UIAlertAction * action) {}];

AlertView is depricated in iOS 8.So we need to use UIAlertController.

UIAlertController * alert = [UIAlertController
            alertControllerWithTitle:@"Title"
                             message:@"Message"
                      preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *actionAccessAddressbook = [UIAlertAction
                    actionWithTitle:@"Access"
                              style:UIAlertActionStyleDefault
                            handler:^(UIAlertAction * action) {
                         [self displayFindFriendView:[NSNumber numberWithInteger: CS_CONTACTS ]];
                            }];

UIAlertAction *actionFindFriendEmail = [UIAlertAction
                        actionWithTitle:@"Find Friend Email"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   //...Do your stuff here
                                }];

UIAlertAction *actionLogout = [UIAlertAction
                        actionWithTitle:@"Logout"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                   [self userLogout];
                                }];
UIAlertAction *actionClearSearchHistory = [UIAlertAction
                        actionWithTitle:@"ClearSearchHistory"
                                  style:UIAlertActionStyleDefault
                                handler:^(UIAlertAction * action) {
                                  [[CSCoreDataHandler sharedInstance] deleteManagedObjectsInModel:@"CSRecentSearch"];
                                }];


[alert addAction:actionAccessAddressbook];
[alert addAction:actionFindFriendEmail];
[alert addAction:actionLogout];
[alert addAction:actionClearSearchHistory];

[self presentViewController:alert animated:YES completion:nil];
