iOS實現封裝一個獲取通訊錄的工具類詳解

前言

本文給大家介紹了關于iOS如何封裝一個獲取通訊錄工具類的相關內容，iOS獲取通訊錄一共有4個framework: AddressBook, AddressBookUI, Contacts, ContactsUI; 其中 AddressBook 和 AddressBookUI 已經被iOS9時 deprecated 了, 而推出了Contacts 和 ContactsUI 取代之. 其中 AddressBookUI 和 ContactsUI 是picker出一個界面提供選擇一條聯系人信息并且是不需要手動授權, AddressBook 和 Contacts 是獲取全部通訊錄數據并且需要手動授權.下面來一起看看詳細的介紹吧。

注意：在iOS10獲取通訊錄權限需主動在info.plist里添加上提示信息. 不然會崩潰. 在info.plist里添加一對key和value

key: Privacy - Contacts Usage Description
value: 自由發揮, 這里隨便寫一句: 是否允許此App訪問你的通訊錄?

ContactsModel

新建兩個數據模型文件來保存獲取的通訊錄數據

ContactsModel.h

#import <Foundation/Foundation.h>

@interface ContactsModel : NSObject
@property (nonatomic, copy) NSString *num;
@property (nonatomic, copy) NSString *name;

- (instancetype)initWithName:(NSString *)name num:(NSString *)num;
@end

ContactsModel.m

#import "ContactsModel.h"

@implementation ContactsModel

- (instancetype)initWithName:(NSString *)name num:(NSString *)num {
 if (self = [super init]) {
  self.name = name;
  self.num = num;
 }
 return self;
}

@end

ContactsHelp

這是獲取通訊錄的工具類.

ContactsHelp.h

#import <UIKit/UIKit.h>
#import "ContactsModel.h"

typedef void(^ContactBlock)(ContactsModel *contactsModel);

@interface ContactsHelp : NSObject

+ (NSMutableArray *)getAllPhoneInfo;

- (void)getOnePhoneInfoWithUI:(UIViewController *)target callBack:(ContactBlock)block;

@end

使用

...

@property(nonatomic, strong) ContactsHelp *contactsHelp;

...

- (IBAction)btn_getOne {

 [self.contactsHelp getOnePhoneInfoWithUI:self callBack:^(ContactsModel *contactModel) {
  NSLog(@"-----------");
  NSLog(@"%@", contactModel.name);

}

- (IBAction)btn_getAll {
