类似的做法如之前这篇随笔：114自定义 UITableViewCell 实现好友列表（扩展知识：如何使用xib创建自定义的表格视图单元格 KMTableViewCell）
相比之下：自定义 UITableViewCell 的内容灵活，可根据需求调整展示效果，应用场景更广；一般适用于TableView 自带的单元格样式无法实现的效果。
效果如下：
ViewController.h
1 #import <UIKit/UIKit.h> 2 3 @interface ViewController : UITableViewController 4 @property (strong, nonatomic) NSMutableArray *mArrDataList; 5 @property (strong, nonatomic) NSMutableArray *mArrImageList; 6 @property (assign, nonatomic) UITableViewCellAccessoryType accessoryType; 7 8 @end
