封装scrollView 循环滚动，tableViewCell（连载） mvc

封装 封装 封装 。。。

封装的重要性太重要了 给大家在送点干货

从一个项目中抽取出来的。和大家一起分享 封装scrollView 循环滚动。tableViewCell（连载）

明天还会更新 tableView 的封装

使用了mvc 设计模式

代码例如以下：

//
// GPMainController.m#import "GPMainController.h"
#import "GPAdsView.h"
#import "GPSubViewCell.h"
#import "GPSubject.h"@interface GPMainController ()<GPAdsViewDelegate,UITableViewDataSource,UITableViewDelegate>

@property(nonatomic,strong)NSArray *subjects;@end@implementation GPMainController/**
