为了兼容iOS9以前与iOS9以后用到的通讯录fromework,做了这个封装，方便调用CNContactStore和AddressBook

需要导入的头文件

//ios9之前导入的框架
#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>
//ios9之后导入的框架
#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>

封装的.h文件

#import <Foundation/Foundation.h>
@class UIViewController;

extern NSString *const contactNameKey;/*!通讯录人名key*/
extern NSString *const contactPhoneKey;/*!通讯录手机号key*/



/**
 选择通讯录联系人之后的回调

 @param dic 回调返回的参数，key请参考contactNameKey,contactPhoneKey;
 */
typedef void(^SelectContactBackBlock)(NSDictionary *dic);

 @param fromVc 打开通讯录的VC
 @param contactBackBlock 选取某个通讯录人之后的回调

解释说明

• 在等待用户授权通讯录的地方使用了信号量semaphore，目的是为了同步到用户的授权状态再反馈给使用者
• 点击获取的通讯录数据保存在字典里，使用的key分别为：

extern NSString *const contactNameKey;/*!通讯录人名key*/
extern NSString *const contactPhoneKey;/*!通讯录手机号key*/

• 需要配置plist文件

<key>NSContactsUsageDescription</key>
<string>方便您填写联系人</string>
