iOS中获取本地通讯录联系人以及汉字首字母排序
iOS中获取手机通讯录中的联系人信息:
- /*** 加载本地联系人*/
- - (void)loadLocalContacts
- {
- //新建一个通讯录类
- ABAddressBookRef addressBooks = nil;
- if (DeviceVersion < 6.0) {
- addressBooks = ABAddressBookCreate();
- } else {
- addressBooks = ABAddressBookCreateWithOptions(NULL, NULL);
- //获取通讯录权限
- dispatch_semaphore_t sema = dispatch_semaphore_create(0);
- ABAddressBookRequestAccessWithCompletion(addressBooks, ^(bool granted, CFErrorRef error){dispatch_semaphore_signal(sema);});
- dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
- dispatch_release(sema);
- }
- //判断授权状态
- if (ABAddressBookGetAuthorizationStatus()!=kABAuthorizationStatusAuthorized) {
- return ;
- }
- //获取通讯录中的所有人
- CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBooks);
- //通讯录中人数
- CFIndex nPeople = ABAddressBookGetPersonCount(addressBooks);
- NSMutableArray *persons = [[NSMutableArray alloc] init];
- for (int i = 0; i < nPeople; i++) {
- //获取个人
- ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);
- //获取个人名字
- NSString *firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
- NSString *lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
- NSMutableString *name = [[NSMutableString alloc] init];
- if (firstName == nil && lastName == nil) {
- NSLog(@"名字不存在的情况");
- name = nil;
- }
- if (lastName) {
- [name appendString:lastName];
- }
- if (firstName) {
- [name appendString:firstName];
- }
- ABMultiValueRef tmlphone = ABRecordCopyValue(person, kABPersonPhoneProperty);
- NSString *telphone = (NSString *)ABMultiValueCopyValueAtIndex(tmlphone, 0);
- if (telphone != nil) {
- telphone = [telphone stringByReplacingOccurrencesOfString:@"-" withString:@""];
- NSString *title = [NSString stringWithFormat:@"%@(%@)",name,telphone];
- [persons addObject:title];
- }
- }
- //对联系人进行分组和排序
- UILocalizedIndexedCollation *theCollation = [UILocalizedIndexedCollation currentCollation];
- NSInteger highSection = [[theCollation sectionTitles] count]; //中文环境下返回的应该是27,是a-z和#,其他语言则不同
- //_indexArray 是右侧索引的数组,也是secitonHeader的标题
- _indexArray = [[NSMutableArray alloc] initWithArray:[theCollation sectionTitles]];
- NSMutableArray *newSectionsArray = [[NSMutableArray alloc] initWithCapacity:highSection];
- //初始化27个空数组加入newSectionsArray
- for (NSInteger index = 0; index < highSection; index++) {
- NSMutableArray *array = [[NSMutableArray alloc] init];
- [newSectionsArray addObject:array];
- [array release];
- }
- for (NSString *p in persons) {
- //获取name属性的值所在的位置,比如"林丹",首字母是L,在A~Z中排第11(第一位是0),sectionNumber就为11
- NSInteger sectionNumber = [theCollation sectionForObject:p collationStringSelector:@selector(getFirstLetter)];
- //把name为“林丹”的p加入newSectionsArray中的第11个数组中去
- NSMutableArray *sectionNames = newSectionsArray[sectionNumber];
- [sectionNames addObject:p];
- }
- for (int i = 0; i < newSectionsArray.count; i++) {
- NSMutableArray *sectionNames = newSectionsArray[i];
- if (sectionNames.count == 0) {
- [newSectionsArray removeObjectAtIndex:i];
- [_indexArray removeObjectAtIndex:i];
- i--;
- }
- }
- //_contacts 是联系人数组(确切的说是二维数组)
- self.contacts = newSectionsArray;
- [newSectionsArray release];
- [self.tableView reloadData];
- }
顺便把索引和tableView dataSource的代理方法也贴一下:
- - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
- {
- return self.contacts.count;
- }
- - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
- {
- return [self.contacts[section] count];
- }
- - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
- {
- static NSString *identifier = @"contactCell";
- UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
- if (cell == nil) {
- cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
- }
- cell.imageView.image = [UIImage imageNamed:@"default_head"];
- cell.textLabel.text = [self.contacts objectAtIndex:indexPath.section][indexPath.row];
- return cell;
- }
- - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
- {
- return [_indexArray objectAtIndex:section];
- }
- - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
- {
- return _indexArray;
- }
- //索引列点击事件
- - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
- {
- return index;
- }
还有两个很重要的方法:
下面这个方法是[theCollation sectionForObject:p collationStringSelector:@selector(getFirstLetter)]; 是这里的p对象要实现的方法,我这里的p是NSString,你也可以用其他对象例如Person。
- - (NSString *)getFirstLetter {
- NSString *ret = @"";
- if (![self canBeConvertedToEncoding: NSASCIIStringEncoding]) {//如果是英语
- if ([[self letters] length]>2) {
- ret = [[self letters] substringToIndex:1];
- }
- }
- else {
- ret = [NSString stringWithFormat:@"%c",[self characterAtIndex:0]];
- }
- return ret;
- }
下面这个方法是NSString得类别方法
- - (NSString *)letters{
- NSMutableString *letterString = [NSMutableString string];
- int len = [self length];
- for (int i = 0;i < len;i++)
- {
- NSString *oneChar = [[self substringFromIndex:i] substringToIndex:1];
- if (![oneChar canBeConvertedToEncoding:NSASCIIStringEncoding]) {
- NSArray *temA = makePinYin2([oneChar characterAtIndex:0]);
- if ([temA count]>0) {
- oneChar = [temA objectAtIndex:0];
- }
- }
- [letterString appendString:oneChar];
- }
- return letterString;
- }
