UI：用UITableView制作通讯录的关键代码

分析{功能分析(打电话、添加联系人、修改联系人)，模块分析（联系人展示、详情模块、添加模块）}

拿到一个项目，首先分析项目框架(工程框架)

首先：判断是否是用户第一次安装：（如果是的，那就加载用户引导页面）（如果不是，那就显示用户联系人的主页面）

其次：用户联系人的主页面VC（用一个协助类 addressbookheleper类（做数据处理相关的内容，属于MVC的M层。只处理相关的数据，这里是为VC瘦身）去提供相应的方法 给 controller (ContactListViewController) ）这里面有这几个方法：为VC提供tableViewCell某一分区得到行数、分区个数、对应的分区的标题、右侧的索引、是否要删除某分区、是否要删除某一行、移动某分区的某一行、返回对应行的联系人、添加联系人。

#import <UIKit/UIKit.h>
@class Contact;

//为 callBtn 制订协议，实现拨打电话
@protocol MakeACallDelegate <NSObject>

-(void)dial:(NSIndexPath *)indexPath;

@end

@interface CustomContactCellTabviewCell : UITableViewCell
@property (nonatomic ,retain) UIImageView *photoView;
@property (nonatomic ,retain) UILabel *nameLabel;
@property (nonatomic ,retain) UILabel *phoneLabel;
@property (nonatomic ,retain) UIButton *callBtn;
@property(nonatomic,assign)id<MakeACallDelegate>delegate;
@property(nonatomic,retain)NSIndexPath * indexPath;//存储当前点击 call 的索引
@property(nonatomic,retain)Contact * contact;//声明一个联系人对象的属性
//为cell 上的控件赋值
-(void)configureCell:(Contact *)contact;
