簡單的iOS通訊錄操作封裝（新增連絡人...、檢查號碼是否存在）

SJABHelper.h

#import <Foundation/Foundation.h>enum {    ABHelperCanNotConncetToAddressBook, /**< 串連通訊錄失敗（iOS6之後訪問通訊錄需要使用者許可） */    ABHelperExistSpecificContact, /**< 號碼已存在 */    ABHelperNotExistSpecificContact /**< 號碼不存在 */};typedef NSUInteger ABHelperCheckExistResultType;@interface SJABHelper : NSObject/** *    新增連絡人... * *    @param     name     連絡人姓名 *    @param     num     電話號碼 *    @param     label     電話號碼的標籤備忘 * *    @return    是否添加成功 */+ (BOOL)addContactName:(NSString*)name phoneNum:(NSString*)num withLabel:(NSString*)label;/** *    查詢指定號碼是否已存在於通訊錄中 * *    @param     phoneNum     電話號碼 * *    @return    返回查詢結果，詳見枚舉類型注釋 */+ (ABHelperCheckExistResultType)existPhone:(NSString*)phoneNum;@end

 

SJABHelper.m

需要注意的就是iOS6中新的使用者隱私保護使得調用 ABAddressBookCreate() 時會彈出alert讓使用者確認是否允許，需要加上代碼：

　　// 如果為iOS6以上系統，需要等待使用者確認是否允許訪問通訊錄。    if ([[UIDevice currentDevice].systemVersion floatValue] >= 6.0)    {        addressBook = ABAddressBookCreateWithOptions(NULL, NULL);        //等待同意後向下執行        dispatch_semaphore_t sema = dispatch_semaphore_create(0);        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error)                                                 {                                                     dispatch_semaphore_signal(sema);                                                 });        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);         dispatch_release(sema);     } 

不然addressBook在使用者確認操作前是NULL，調用會導致程式crash。
