IOS -- Address Book (UITableViewController), uitableview address book

This article mainly implements some functions of the address book (group name, index, group name) and so on:

If you don't talk much about it, go first:

 

You need to import a plist file in the project. The file diagram is as follows:

Project directory file:

 

 

Engineering procedures:

RootTableViewController. h

 

#import <UIKit/UIKit.h>@interface RootTableViewController : UITableViewController@property(strong,nonatomic) NSDictionary *dic;@property(strong,nonatomic) NSArray *arrkeys;@end

Note:

Various attributes and display specifications in the address book are set in RootTableViewController. m !!!
