我要评论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 *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;
}
