一，(AddressBook.framework)编辑通讯录 Crash
环境：
release 环境（pn1 release 或者 dn1 release）
场景：
编辑联系人信息
Crash 信息：
2019-07-23 17:36:45.836520+0800 DingtoneBeta[2050:123112] *** Terminating app due to uncaught exception 'CNPropertyNotFetchedException', reason: 'Contact 0x13f2132e0 is missing some of the required key descriptors: (
"<CNAggregateKeyDescriptor: 0x283efc980: kind=+[CNContactContentViewController descriptorForRequiredKeys]>"
)'
代码如下：
- (void)editSystemContact {
[[ServiceMgr sharedServiceMgr].GAITrack sendEventWithCategory:kUserOperatorUsageCategory
withAction:@"EditSystemContactFrom_ContactInfo"
withLabel:nil
withValue:nil];
if (![[DTNetWorkAlertViewCtrl sharedInstance] isLoginDoneAndShowAlertView]) {
return;
}
ABAddressBookRef addressBook = nil;
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
} else {
[NUtils showAlertUnableToAccessContactWithText:NSLocalizedString(@"Dingtone is unable to access contact information from the address book.To share a contact with your friend, Dingtone needs to access the address book.Please enable Dingtone access address book from Settings=>Privacy.", @"")];
return;
}
ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBook, (ABRecordID) self.contactInfo.localId);
if (!person) {
CFRelease(addressBook);
return;
}
self.isJumpToEditSystemContact = YES;
ABPersonViewController *personVc = [[ABPersonViewController alloc] init];
personVc.displayedPerson = person;
personVc.personViewDelegate = self;
personVc.allowsEditing = YES;
personVc.allowsActions = NO;
personVc.shouldShowLinkedPeople = NO;
personVc.addressBook = addressBook;
self.personVc = personVc;
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:personVc];
personVc.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", nil)
style:UIBarButtonItemStylePlain
target:self
action:@selector(editSystemPageDidClickBack)];
[[ServiceMgr getBaseViewController] presentViewController:nav animated:YES completion:nil];
CFRelease(addressBook);
}
分析流程：
在 iOS 13 上必定会 Crash，目前没有找到处理方法，只能通过 Contacts.framework 处理。
思路：
由于项目中使用的是 AddressBook.framework，通过 ABRecordID 来指定用户进行编辑，因此只能通过 ABRecordRef 对象获取 CN 对象的 identifier
typedef int32_t ABRecordID AB_DEPRECATED("use CN object's identifier");
通过调试可以看到 person 对象是一个 ABSPerson 类型，并且私有属性 _cnImpl 是一个 CNContact 对象，通过 CNContact 对象可以获取到 identifier

获取 identifier：
1，__bridge 获取 Objective-C 对象
2，通过 kvc 获取私有属性
CNContact *contact = [(__bridge NSObject *)person valueForKey:@"_cnImpl"];
NSString *identifier = contact.identifier;
最终解决代码：
- (void)editSystemContact {
ABAddressBookRef addressBook = nil;
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
} else {
[NUtils showAlertUnableToAccessContactWithText:NSLocalizedString(@"Dingtone is unable to access contact information from the address book.To share a contact with your friend, Dingtone needs to access the address book.Please enable Dingtone access address book from Settings=>Privacy.", @"")];
return;
}
ABRecordRef person = ABAddressBookGetPersonWithRecordID(addressBook, (ABRecordID) self.contactInfo.localId);
if (!person) {
CFRelease(addressBook);
return;
}
if (@available(iOS 13, *)) {
// 获取 identifier
CNContact *contact = [(__bridge NSObject *)person valueForKey:@"_cnImpl"];
NSString *identifier = contact.identifier;
NSLog(@"contact = %@, identifier = %@", contact, identifier);
[[LJContactManager sharedInstance] editSystemContactWithIdentifier:identifier
controller:[ServiceMgr getBaseViewController]
backTitle:NSLocalizedString(@"Back", nil)
editBackBlock:^{
[[LJContactManager sharedInstance] setContactChangeHandler:nil];
}];
CFRelease(addressBook);
} else {
ABPersonViewController *personVc = [[ABPersonViewController alloc] init];
personVc.displayedPerson = person;
personVc.personViewDelegate = self;
personVc.allowsEditing = YES;
personVc.allowsActions = NO;
personVc.shouldShowLinkedPeople = NO;
personVc.addressBook = addressBook;
self.personVc = personVc;
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:personVc];
personVc.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", nil)
style:UIBarButtonItemStylePlain
target:self
action:@selector(editSystemPageDidClickBack)];
[[ServiceMgr getBaseViewController] presentViewController:nav animated:YES completion:nil];
CFRelease(addressBook);
}
}
