[英]ABPeoplePickerNavigationController crashes in IOS 7
I have problem with ABPeoplePickerNavigationController in IOS 7 with the following error 我在IOS 7中遇到ABPeoplePickerNavigationController的问题,并出现以下错误
*** -[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 在IOS 6上运行正常,但是在ios 7中,如果启用了没有僵尸的僵尸,则会出现此错误,就像
Thread 1: EXC_BAD_ACCESS(code=2,address=0x0)
than i enable zombies 比我启用僵尸
here is my code 这是我的代码
- (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.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancel:)];
}
-(IBAction)addPerson:(id)sender{

{
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 一旦Peoplepickercontroller被解雇,应用程序在ios 7中崩溃
*** -[ABPeoplePickerNavigationController respondsToSelector:]: message sent to deallocated instance 0xb236c00

Thread 1:EXC_BREAKPOINT (code=EXC_1386_BPT,sucode 0x0)
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). 尝试在关闭前将peopleViewController委托设置为nil,并在一段时间内禁用此操作的第二次可能调用(例如,如果用户多次按下按钮)。 Assume you have a reference to ABPeoplePickerNavigationController instance. 假设您有对ABPeoplePickerNavigationController实例的引用。 Something name like self.adressBook; 诸如self.adressBook之类的名称;
Then before dismissing PeoplePickerNavigationController set 然后在关闭PeoplePickerNavigationController设置之前
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. 并确保您 在解雇后 不要调用 peoplePickerNavigationController引用,否则对此实例的引用属于weak而不是分配类型。
- (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 我认为这是因为未保留创建的视图控制器,请调用[self addChildViewController:picker]或为其维护“强”引用
