4 ways to get a list of IOS _ios

This example for you to share the iOS access to the Address Book 4 ways for Everyone to refer to, the specific content as follows

Working with scenes

Some apps use phone numbers to recommend friends, such as Weibo, Alipay

First, the client will get all the phone number in the address Book and then submit the mobile phone number to the app server, the server will look for each cell phone number corresponding to the app account, such as QQ number returned to the client, and then the client based on the server returned to the list of accounts to recommend friends.

Get Contact Way

Programme I: Addressbookui.framework framework

Provides a contact list interface, contact details interface, add contact interface, etc.
Generally used to select contacts

Programme II: Addressbook.framework framework:
No UI interface, you need to build your own contact interface
Pure C language API, just get contact data
Most data types are core Foundation
Starting from iOS6, you need to get the user's authorization to access the Address Book

Programme III: Third-party framework: Rhaddressbook
To encapsulate a addressbook.framework

Programme IV: iOS9.0 The latest Address Book framework
Contactsui.framework: Alternatives to option 1, features: object-oriented, simple to use, interface
Contacts.framework: Alternatives to Option 2, features: object-oriented, simple to use, five interfaces

programme I: addressbookui.framework

Implementation steps:

1. Create a controller to select a contact
2. Set up Agent: Used to receive user-selected contact information
3. Pop-up Contact Controller
4. Implementing the Proxy method
5. Get contact information in the corresponding proxy method

Addressbook.frame implementation steps:

1. Request for authorization
2. Determine the status of authorization to continue if authorized, if not authorized to prompt the user
3. Create the Address Book object
4. Get all the contacts from the Address Book
5. Iterate through all the contacts
6. Releasing objects that are no longer in use

Addreesbook.framework Specific implementation:

1. Appdelegate request Authorization when application starts

#import "AppDelegate.h"
#import <AddressBook/AddressBook.h>

@interface appdelegate ()

@end

@ Implementation Appdelegate

-(BOOL) Application: (UIApplication *) application didfinishlaunchingwithoptions: ( Nsdictionary *) launchoptions {
 //Override point for customization after application launch.

 [Self requestauthorizationaddressbook];
 Return YES
}


-(void) Requestauthorizationaddressbook {
 //Judge whether authorization
 abauthorizationstatus authorizationstatus = Abaddressbookgetauthorizationstatus ();
 if (Authorizationstatus = = kabauthorizationstatusnotdetermined) {
  //Request Authorization
  abaddressbookref addressbookref = Abaddressbookcreate ();
  Abaddressbookrequestaccesswithcompletion (Addressbookref, ^ (bool granted, cferrorref error) {
   if (granted) {// Authorization succeeded

   } else {  //Authorization failed
    NSLog (@) Authorization failed! ");
   }
  });
 }
}
@end

2. iOS10 needs to be configured in Info.plist nscontactsusagedescription

<key>NSContactsUsageDescription</key>
<string> request access to address Book </string> 

3. Viewcontroller

#import "ViewController.h" #import <AddressBook/AddressBook.h> @interface Viewcontroller () @end @implementation

4. Operating Results

Third-party framework: Rhaddressbook

Https://github.com/heardrwt/RHAddressBook

The framework uses MRC to manage memory, and if you drag the source code directly into it, you need to set up a compilation tag for each file:-fno-objc-arc, set up also will be an error, the project used some methods too old, many do not support, so this way is not adopted; You can play the project as a static library, or you can drag the project directly into your own project as a dependent

1. Drag rhaddressbook.xcodeproj directly into the project

2. Add target dependencies and link Binary with libraries

3.Build settings-> Other Linker Flags:-OBJC

Error for resolving system classification cannot find method

4.IOS10 needs to be configured in Info.plist nscontactsusagedescription

Select an interface for more than one contact:
