我是靠谱客的博主温暖鸡，最近开发中收集的这篇文章主要介绍iOS实现联系人列表功能，觉得挺不错的，现在分享给大家，希望可以做个参考。
概述

本文实例为大家分享了iOS实现联系人列表功能的具体代码，供大家参考，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
 
@implementation LinkMan

    gPeopleArr = nil;
    gMarkKeyArr = nil;
}

    [super viewDidLoad];
    //清空选择联系人
    NSUserDefaults *userInfoDefaults = [NSUserDefaults standardUserDefaults];
    [userInfoDefaults setObject:nil forKey:@"linkmanSelectList"];
    [userInfoDefaults synchronize];
    
    //标题栏
    [self cTitleBar];
    
    //右侧选择栏
    gMarkKeyArr = [[NSMutableArray alloc] init];
    gPeopleArr = [[NSMutableArray alloc] init];
    gLinkManArr = [[NSMutableArray alloc] init];
  
    //网络数据请求

}

    float height = 44;
    if(ver >= 7){
        height = 64;
    }
    CGRect titleRect = _titleView.frame;
    titleRect.size.height = height;
    [_titleView setFrame:titleRect];
