IOS 通讯录的模糊查询

1、首先拿到通讯录

-(void)ReadAllPeoples

{

[contactsremoveAllObjects];

ABAddressBookRef addressBook =ABAddressBookCreateWithOptions(nil,nil);

dispatch_semaphore_t sema =dispatch_semaphore_create(0);

ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted,CFErrorRef error)

{

dispatch_semaphore_signal(sema);

});

dispatch_semaphore_wait(sema,DISPATCH_TIME_FOREVER);

CFArrayRef results =ABAddressBookCopyArrayOfAllPeople(addressBook);

for(int i =0; i < CFArrayGetCount(results); i++)

{

ABRecordRef person = CFArrayGetValueAtIndex(results, i);

NSString *lastname = (__bridgeNSString*)ABRecordCopyValue(person,kABPersonLastNameProperty);

NSLog(@"lastname:%@",lastname);

ABMultiValueRef phone =ABRecordCopyValue(person,kABPersonPhoneProperty);

//读取联系人信息

for (int k =0; k<="" p="">

{

NSString * personPhone = (__bridgeNSString*)ABMultiValueCopyValueAtIndex(phone, k);

if (lastname == nil) {

lastname =@"";

}

if (person == nil) {

continue;

}

//此句为存储结构，contacts为NSMutableArray*

[contactsaddObject:@[lastname,personPhone]];

}

}

CFRelease(results);

CFRelease(addressBook);

[self.tableViewreloadData];

}

2、对姓名（lastname）和手机号（personPhone）的模糊查询

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self[0] contains [cd] %@||self[1] contains [cd] %@",用户输入的string,用户输入string];

filterData = [[NSArrayalloc] initWithArray:[contactsfilteredArrayUsingPredicate:predicate]];

filterData就是查询到的结果
