你可以这样做
-(void)RemoveContactGroup:(NSString *)name {
BOOL flag = [self CheckIfGroupExistWithName:name];
if(!flag)
{
return;
}
CFErrorRef error = NULL;
ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate();
ABRecordRef newGroup;
//if Existing Group
newGroup = ABAddressBookGetGroupWithRecordID(iPhoneAddressBook,groupId);
NSArray *member = (__bridge NSArray *)ABGroupCopyArrayOfAllMembers(newGroup);
int nPeople = (int)[member count];
if (nPeople>0)
{
for (int i=0; i<nPeople; i++)
{
ABRecordRef contactPerson = (__bridge ABRecordRef)member[i];
ABAddressBookRemoveRecord(iPhoneAddressBook, (ABRecordRef)contactPerson, &error);
}
}
ABAddressBookSave(iPhoneAddressBook, NULL);
CFRelease(newGroup);
}
首先,您可以检查组是否存在,如果存在则给出组 id
-(BOOL)CheckIfGroupExistWithName:(NSString*)groupName {
hasGroup = NO;
//checks to see if the group is created ad creats group for HiBye contacts
ABAddressBookRef addressBook = ABAddressBookCreate();
CFIndex groupCount = ABAddressBookGetGroupCount(addressBook);
CFArrayRef groupLists= ABAddressBookCopyArrayOfAllGroups(addressBook);
for (int i=0; i<groupCount; i++) {
ABRecordRef currentCheckedGroup = CFArrayGetValueAtIndex(groupLists, i);
NSString *currentGroupName = (__bridge NSString *)ABRecordCopyCompositeName(currentCheckedGroup);
if ([currentGroupName isEqualToString:groupName]){
//!!! important - save groupID for later use
groupId = ABRecordGetRecordID(currentCheckedGroup);
hasGroup=YES;
}
CFRelease(currentCheckedGroup);
}
if (hasGroup==NO){
//id the group does not exist you can create one
}
return hasGroup;
}
核实。
