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 "LinkmanCell.h"
#import "LinkmanSelectCell.h"
#import "pinyin.h"
#import "ChineseString.h"

@property (weak, nonatomic) IBOutlet UIView *titleView; //标题栏

@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
