ABPeoplePickerNavigationController crashes in IOS 7 - iphone

Question

I have problem with ABPeoplePickerNavigationController in IOS 7 with the following error
*** -[ABPeoplePickerNavigationController respondsToSelector:]: message sent to deallocated instance 0x9b4b050
on IOS 6 it is working fine but in ios 7 it gives this error with zombies enabled without zombies it was like
Thread 1: EXC_BAD_ACCESS(code=2,address=0x0)
than i enable zombies
here is my code
- (void)viewDidLoad
{
[super viewDidLoad];
self.contacts = [[NSMutableArray alloc] initWithCapacity:10];
self.addressBook=ABAddressBookCreateWithOptions(NULL, NULL);
[self checkAddressBookAccess];
}
(void)requestAddressBookAccess
{
ContactsViewController * __weak weakSelf = self;
ABAddressBookRequestAccessWithCompletion(self.addressBook, ^(bool granted, CFErrorRef error)
{
if (granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
[weakSelf accessGrantedForAddressBook];
});
}
});
}
-(void)accessGrantedForAddressBook
{
NSMutableArray *savedContacts=[[NSMutableArray alloc] initWithArray:[DatabaseHandler getAllContacts]];
if (savedContacts &&savedContacts.count!=0)
[self.contacts addObjectsFromArray:savedContacts];
}
- (IBAction)popUpAddExistingContact:(id)sender {
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[picker setDelegate:self];
[self presentViewController:picker animated:YES completion:nil];
}
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
NSString *viewControllerDesc=[viewController description];
NSString *t_st = #"ABContactViewController";
NSRange rang =[viewControllerDesc rangeOfString:t_st options:NSCaseInsensitiveSearch];
if (rang.length == [t_st length])
{
navigationController.topViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(addPerson:)];
}
else if([navigationController isKindOfClass:[ABPeoplePickerNavigationController class]] && [viewController isKindOfClass:[ABPersonViewController class]])
{
ABPersonViewController *DVC=(ABPersonViewController*)viewController;
self.currentPerson=DVC.displayedPerson;
navigationController.topViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(addPerson:)];
}
else{
navigationController.topViewController.navigationItem.rightBarButtonItem = nil;
}
navigationController.topViewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(cancel:)];
}
-(IBAction)addPerson:(id)sender{
if (self.currentPerson!=NULL)
{
CFStringRef firstName;
int recordID;
firstName = ABRecordCopyValue(self.currentPerson, kABPersonFirstNameProperty);
recordID = ABRecordGetRecordID(self.currentPerson);
MyContact *contact=[[MyContact alloc] init];
contact.Name=(__bridge NSString *)(firstName);
contact.contactID=[NSString stringWithFormat:#"%i",recordID];
contact.phones=[[NSMutableArray alloc] init];
ABMultiValueRef phones = ABRecordCopyValue(self.currentPerson, kABPersonPhoneProperty);
for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++)
{
CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(phones, j);
CFStringRef locLabel = ABMultiValueCopyLabelAtIndex(phones, j);
NSString *phoneNumber = (__bridge NSString *)phoneNumberRef;
[contact.phones addObject:phoneNumber];
CFRelease(phoneNumberRef);
CFRelease(locLabel);
}
CFRelease(firstName);
//CFRelease(lastName);
}
//[self dismissModalViewControllerAnimated:YES];
[self dismissViewControllerAnimated:YES completion:^(void ){
[self.popUpContactView removeFromSuperview];
}];
}
as soon as peoplepickercontroller is dismissed app crashed in ios 7

Answer 1

try to set peopleViewController delegates to nil before dismissing and disable second possible call of this action during some time (like if user pressed button several times). Assume you have a reference to ABPeoplePickerNavigationController instance. Something name like self.adressBook;
Then before dismissing PeoplePickerNavigationController set
self.adressBook.peoplePickerDelegate = nil
self.adressBook.delegate = nil;
and make sure that you do not call your peoplePickerNavigationController reference after dismissing or your reference to this instance is of weak, not assign type.

Answer 2

- (IBAction)popUpAddExistingContact:(id)sender {
ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[picker setDelegate:self];
[self presentViewController:picker animated:YES completion:nil];
}
I think it is because the view controller created is not retained,
Call [self addChildViewController:picker] or else maintain a "strong" reference for it
