十二，iOS通讯录好友信息的获取

1，先是通过方法获取数据，然后通过tableview展示出来，在底部有访问按钮

2，首先要导入头文件#import <ContactsUI/ContactsUI.h>，其次声明代理CNContactPickerDelegate

3，具体代码如下，其中有些是自己定义的宏看着改下

#define W [UIScreen mainScreen].bounds.size.width
#define H [UIScreen mainScreen].bounds.size.height

#import "ContactAccessViewController.h"
#import <ContactsUI/ContactsUI.h>
@interface ContactAccessViewController ()<CNContactPickerDelegate,UITableViewDelegate,UITableViewDataSource>

@property (nonatomic, strong) UITableView *table;

@property (nonatomic, strong) NSArray *menuList;

@property (nonatomic, strong) NSArray *infoList;

@property (nonatomic, strong) UIButton *contactBtn;

@property (nonatomic, strong) NSMutableArray *dataSource;
@end

@implementation ContactAccessViewController
