我需要阻止在我们的应用程序中显示联系人组,但是用户只需从AddressBook中删除组即可。所以我试图在显示联系人之前删除它们,然后在完成后将它们添加回来,以便AddressBook保持不变,iOS Contacts应用程序按原样显示组。我创建了两个用于存储信息的数组:
NSArray *aGroups;
NSMutableArray *aGroupMembers;
我删除组,存储它们,并在viewWillAppear中显示选择器:
// Remove group records for the life of this view.
CFErrorRef error;
ABAddressBookRef abRef = ABAddressBookCreate();
NSArray *groups = (NSArray *)ABAddressBookCopyArrayOfAllGroups(abRef);
if (groups.count > 0) {
// we will remove the groups so save for restoration
self.aGroups = [[NSArray alloc] initWithArray:groups];
aGroupMembers = [[NSMutableArray alloc] initWithCapacity:groups.count];
for (int i = 0; i < groups.count; i++) {
NSArray *members = (NSArray *)ABGroupCopyArrayOfAllMembers([groups objectAtIndex:i]);
NSMutableArray *memberIDs = [[NSMutableArray alloc] initWithCapacity:[members count]];
for (id member in members) {
ABRecordID ID = ABRecordGetRecordID(member);
[memberIDs addObject:[NSNumber numberWithInteger:ID]];
}
[aGroupMembers insertObject:memberIDs atIndex:i];
CFRelease(members);
[memberIDs release];
// Remove the group from the addressbook
ABAddressBookRemoveRecord(abRef, [groups objectAtIndex:i], &error);
}
CFRelease(groups);
ABAddressBookSave(abRef, nil);
self.picker.addressBook = abRef;
}
CFRelease(abRef);
然后在viewWillDisappear和willResignActive中,我“尝试”重新创建组,将成员重新添加到每个组并添加回地址簿。但是由于ABGroupAddMember()失败,我无法再添加成员。当我检查调试器中的变量时,GroupName和person的firstname都是正确的。我看不到问题,CFErrorRef值没有设置。
// Restore the group records.
if (self.aGroups != nil) {
CFErrorRef error = nil;
CFTypeRef grpName = nil;
CFTypeRef firstName = nil;
ABRecordRef newGroup = nil;
ABAddressBookRef abRef = ABAddressBookCreate();
// Re-create the groups
for (int i = 0; i < self.aGroups.count; i++) {
// Create the new group
newGroup = ABGroupCreate();
grpName = ABRecordCopyValue((ABRecordRef)[self.aGroups objectAtIndex:i], kABGroupNameProperty);
ABRecordSetValue(newGroup, kABGroupNameProperty, grpName, &error);
// Create the members
NSArray *memberIDs = (NSArray*)[aGroupMembers objectAtIndex:i];
for (NSNumber *iD in memberIDs) {
ABRecordRef person = ABAddressBookGetPersonWithRecordID(abRef,iD.intValue);
firstName = ABRecordCopyValue((ABRecordRef)person, kABPersonFirstNameProperty);
BOOL bSuccess = ABGroupAddMember(newGroup, person, &error);
if (!bSuccess) {
//NSString *errorStr = [(NSString *)CFErrorCopyDescription(error) autorelease]; // this cause EXEC_BAD_ACCESS
CFRelease(error);
}
}
CFRelease(newGroup);
CFRelease(grpName);
}
// Save the changes
ABAddressBookSave(abRef, nil);
CFRelease(abRef);
self.aGroups = nil;
[aGroupMembers removeAllObjects];
aGroupMembers = nil;
}

尝试将通过iPhone
协议从Google CardDAV
同步的联系人添加到以编程方式创建的本地群组时发生这种情况。
事实证明,您无法将同步的联系人添加到本地组,反之亦然,但它只返回NO
而不将error
参数设置为任何错误消息,以解释它为什么没有工作。
我在我的应用中通过尝试将联系人添加到群组中解决了它,如果它不起作用,我通过在我的应用中本地保存联系人群组关系来解决它。
不是那么好,如果有人有办法解决这个问题,我很乐意听到。

在尝试使用ABAddressBookAddRecord
向群组添加成员之前,您可能需要使用ABGroupAddMember
将群组记录添加到地址簿中。
