检索通讯录，根据输入的电话号码的每一位下拉显示检索结果

首先建一个model类保存电话本信息

.h里面

{
    NSInteger sectionNumber;
    NSInteger recordID;
    NSString *name;
    NSString *email;
    NSString *tel;
}
@property NSInteger sectionNumber;
@property NSInteger recordID;
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *email;
@property (nonatomic, retain) NSString *tel;

 

model.m里面

#import "PhoneBookModel.h"

@implementation PhoneBookModel
@synthesize name, email, tel, recordID, sectionNumber;
@end

在要检索电话本的类里面引入头文件

#import <UIKit/UIKit.h>
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
#import "PhoneBookModel.h"

实现代理方法

@property (strong, nonatomic) UITableView *tableView;
@property (nonatomic, strong) NSMutableArray *totalBookArr;
@property (nonatomic, strong) NSMutableArray *bianliArr;
@property (nonatomic, strong) NSString *textStr;

@property (nonatomic, assign) BOOL isNameSearch;

这样就可以根据你每一次输入的电话号码检索与之匹配的号码；
