第一大块儿：读取通讯录

1、iOS 6以上系统，争取获取用户允许：

-(id)init{self = [super init];[self createdABHandle];bool  isAuthorized = [self isAuthorizedAddressBook];if (!isAuthorized) {ABAddressBookRequestAccessWithCompletion(_addressBook, ^(bool granted, CFErrorRef error){if (granted){//[self createAddressBuddyData];}});}return self;
}

- (BOOL)isAuthorizedAddressBook {if (SYSTEM_VERSION <= 6.0){return YES;}//ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();if (status == kABAuthorizationStatusNotDetermined) {return NO;}else if(status == kABAuthorizationStatusAuthorized) {return YES;}else if (status == kABAuthorizationStatusDenied) {return NO;}return NO;
}

2、获取联系人。获取联系人分组

ABAddressBookRef addressBook =ABAddressBookCreate();
NSArray* allPeople = CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople (addressBook));
NSArray* allGroups = CFBridgingRelease(ABAddressBookCopyArrayOfAllGroups(addressBook));
for (id person in (NSArray *) allPeople)[self logContact:person];
for (id group in (NSArray *) allGroups)[self logGroup:group];
CFRelease(addressBook);

3、联系人字段获取技巧：

● 获取个人或群体完整名称。

比如：NSString* name ＝ (NSString*)ABRecordCopyCompositeName(record);

● 获取联系人ID ABRecordID recId = ABRecordGetRecordID(record);

● 获取电话。邮箱列表，生日等，多键值的方法 比如：ABMultiValueRef phoneNumbersArr = ABRecordCopyValue(record, kABPersonPhoneProperty);

● 获取联系人分组名称 CFStringRef name = ABRecordCopyValue(group,kABGroupNameProperty);
● 获取联系人分组ID   ABRecordID recId = ABRecordGetRecordID(group);

在获取多值的属性时候须要注意：获取地址的时候，多键值有嵌套。

代码例如以下：

NSArray *allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);int i;
for (i = 0; i < [allPeople count]; i++) {
ABRecordRef record = [allPeople objectAtIndex:i];ABMutableMultiValueRef multiValue = ABRecordCopyValue(record, kABPersonAddressProperty);
for(CFIndex i=0;i<ABMultiValueGetCount(multiValue);i++)
{
NSString* HomeLabel=(NSString*)ABMultiValueCopyLabelAtInde x(multiValue, i);
if([HomeLabel isEqualTo:@"_$!<Home>!$_"])
{CFDictionaryRef dict = ABMultiValueCopyValueAtIndex(multiValueArr, i);NSString* street  =CFBridgingRelease( CFDictionaryGetValue(dict, kABPersonAddressStreetKey));NSString* city     =CFBridgingRelease( CFDictionaryGetValue(dict, kABPersonAddressCityKey));NSString* country  =CFBridgingRelease(CFDictionaryGetValue(dict, kABPersonAddressCountryKey));CFRelease(dict);NSString *syntheticAddress = [NSString stringWithFormat:@"%@, %@, %@",(street?street:@""),(city?city:@""),(country?country:@"")];
}

不能直接调用ABMultiValueCopyValueAtIndex，然后强转成NSString*

4、删除联系人或者群组

ABAddressBookRemoveRecord(addressBook, people, NULL);
ABAddressBookSave(addressBook, NULL);

第二大块儿：写入通讯录

/*更新联系人,比方phoneTypePairArr为空，那么程序把一个空的ABMultiValueRef写入addressBook，达到删除的效果。*/
-(BOOL) updateToAB:(ABRecordRef)person withContact:(RCSContact*)contact{ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, nil);// 保存到联系人对象中，假设属性为nil，则表示要删除//lastnameNSString* lastName = contact.lastName.length?

第三大块儿：监听通讯录变更

client代码须要这么实现：

/*移除注冊函数*/
-(void)dealloc{ABAddressBookUnregisterExternalChangeCallback(_addressBook, ContactsChangeCallback, nil);
}
/*注冊回调函数*/
- (id)init {self = [super init];[self addressBookHandle];ABAddressBookRegisterExternalChangeCallback(_addressBook, ContactsChangeCallback, nil);return self;
}
/*回调函数，实现自己的逻辑。

*/ void ContactsChangeCallback (ABAddressBookRef addressBook, CFDictionaryRef info, void *context){ NSLog(@"ContactsChangeCallback"); }

_addressBook是通讯录句柄。尽管有监听的接口，可是參数info总是空的。

另外：当本APP编辑系统通讯录时候。不会收到通知；通知可能有多个，这时候能够採取：“仅仅处理第一个通知，淹没后面的通知。

”。也能够採取信号量机制，对变更通知一个个在线程中处理。防止界面卡顿。

另外：在加入新的联系人的时候，使用ABNewPersonViewController。特别注意，一定要处理好它的代理：

    // Called when the user selects Save or Cancel. If the new person was saved, person will be// a valid person that was saved into the Address Book. Otherwise, person will be NULL.// It is up to the delegate to dismiss the view controller.
- (void)newPersonViewController:(ABNewPersonViewController *)newPersonView didCompleteWithNewPerson:(ABRecordRef)person;

处理不好，造成APP崩溃。

我的处理是这种：

    [self.navigationController popToViewController:self animated:YES];

监听规则：

当App活跃（前台+后台保活期间）的时候，当通讯录改动的时候，会收到通知

当App不活跃的时候（挂起的时候）。App收不到通知；而是，当App到前台的时候收到延迟的通知。

生成vcard

/**************************************************  @brief  获取通讯录联系列表的vcard*  @param  无*  @retun  无*************************************************/
- (void)getLocalAddressBookvCard {CFArrayRef persons = ABAddressBookCopyArrayOfAllPeople(_addressBook);CFDataRef vcards = (CFDataRef)ABPersonCreateVCardRepresentationWithPeople(persons);NSString *vcardString = [[NSString alloc] initWithData:(__bridge NSData *)vcards encoding:NSUTF8StringEncoding];NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);NSString *folderPath = [paths objectAtIndex:0];NSString *filePath = [folderPath stringByAppendingPathComponent:@"contacts.vcf"];NSLog(@"path = %@",filePath);[vcardString writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:nil];
}

生成到document文件夹下的contacts.vcf文件

还能够用以下的办法。更适合生成单个crad

+(NSData*)exportContactsToVcard:(NSArray*)contacts
{NSMutableArray *people  = [NSMutableArray arrayWithCapacity:contacts.count];ABAddressBookRef ab = ABAddressBookCreate();for (Contact *contact in contacts) {ABRecordRef person = ABAddressBookGetPersonWithRecordID(ab,contact.contactId);[people addObject:(__bridge id)person];}NSData *vCard = (__bridge NSData*)ABPersonCreateVCardRepresentationWithPeople((__bridge CFArrayRef) people);return vCard;
}

从vcard生成person

ABAddressBookRef book = ABAddressBookCreate();
ABRecordRef defaultSource = ABAddressBookCopyDefaultSource(book);
CFArrayRef vCardPeople = ABPersonCreatePeopleInSourceWithVCardRepresentation(defaultSource, vCardData);
for (CFIndex index = 0; index < CFArrayGetCount(vCardPeople); index++) {ABRecordRef person = CFArrayGetValueAtIndex(vCardPeople, index);ABAddressBookAddRecord(book, person, NULL);
}CFRelease(vCardPeople);
CFRelease(defaultSource);
ABAddressBookSave(book, NULL);
CFRelease(book);
