Cell attached views and indentation for IOS development (24)

1 Preface
If we are not satisfied with the ancillary view provided by the ios sdk, We can customize it and indent it.

2. code example
ZYUITableViewController. h:

# Import <UIKit/UIKit. h>
 
@ Interface ZYUITableViewController: UIViewController <UITableViewDelegate, UITableViewDataSource> // Add a proxy
 
@ Property (nonatomic, strong) UITableView * myTableView;
