iOS实现联系人列表功能

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

    nsuserdefaults *userinfodefaults = [nsuserdefaults standarduserdefaults];
    [userinfodefaults setobject:nil forkey:@"linkmanselectlist"];
    [userinfodefaults synchronize];
