这篇文章主要介绍iOS如何实现联系人列表功能，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
具体内容如下
按照顺序排列联系人列表，需要引入一些工具(详见demo)：
主要部分代码：
#import "LinkMan.h"
#import "LinkmanCell.h"
#import "LinkmanSelectCell.h"
#import "pinyin.h"
#import "ChineseString.h"
@interface LinkMan ()<UISearchBarDelegate,UITextFieldDelegate,UITableViewDelegate,UITableViewDataSource>
@property (weak, nonatomic) IBOutlet UILabel *titleLab; //标题
@property (weak, nonatomic) IBOutlet UIView *titleView; //标题栏
@property (weak, nonatomic) IBOutlet UITableView*gTableView; //联系人TV
@property (weak, nonatomic) IBOutlet UIButton *sureBut; //确定
@property (nonatomic ,strong) NSMutableArray *gPeopleArr; //一级联系人
@property (nonatomic ,strong) NSMutableArray *gMarkKeyArr; //标识
@property (nonatomic ,strong) NSMutableArray *gLinkManArr; //二级联系人
@end
