IOS 开发之读取addressbook的实现实例

#import <AddressBook/AddressBook.h> #import <AddressBookUI/AddressBookUI.h> 

//get all people info from the address book ABAddressBookRef addressBook = ABAddressBookCreate(); CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);//这是个数组的引用 for(int i = 0; i<CFArrayGetCount(people); i++){   //parse each person of addressbook   ABRecordRef record=CFArrayGetValueAtIndex(people, i);//取出一条记录   //以下的属性都是唯一的，即一个人只有一个FirstName，一个Organization。。。   CFStringRef firstName = ABRecordCopyValue(record,kABPersonFirstNameProperty);   CFStringRef lastName = ABRecordCopyValue(record,kABPersonLastNameProperty);   CFStringRef company = ABRecordCopyValue(record,kABPersonOrganizationProperty);   CFStringRef department = ABRecordCopyValue(record,kABPersonDepartmentProperty);   CFStringRef job = ABRecordCopyValue(record,kABPersonJobTitleProperty);   //"CFStringRef"这个类型也是个引用，可以转成NSString*   NSlog((NSString *)firstName);   //......   //所有这些应用都是要释放的，手册里是说“you are responsible to release it"   (firstName==NULL)?:CFRelease(firstName);   (lastName==NULL)?:CFRelease(lastName);   (company==NULL)?:CFRelease(company);   (department==NULL)?:CFRelease(department);   (job==NULL)?:CFRelease(job);   //.......   //有些属性不是唯一的，比如一个人有多个电话：手机，主电话，传真。。。   ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);   //所有ABMutableMultiValueRef这样的引用的东西都是这样一个元组（id，label，value）   multiPhone = ABRecordCopyValue(record, kABPersonPhoneProperty);   for (CFIndex i = 0; i < ABMultiValueGetCount(multiPhone); i++) {     CFStringRef labelRef = ABMultiValueCopyLabelAtIndex(multiPhone, i);     CFStringRef numberRef = ABMultiValueCopyValueAtIndex(multiPhone, i);     //可以通过元组的label来判定这个电话是哪种电话，比如下面就包括：主电话，手机，工作传真     if([(NSString *)labelRef isEqualToString:(NSString *) kABPersonPhoneMainLabel]){       person._mainPhone = (NSString *)numberRef;     }else if([(NSString *)labelRef isEqualToString:(NSString *) kABPersonPhoneMobileLabel]){       person._cellPhone = (NSString *)numberRef;     }else if([(NSString *)labelRef compare:(NSString *) kABPersonPhoneWorkFAXLabel]==NSOrderedSame){       person._fax = (NSString *)numberRef;     }     CFRelease(labelRef);     CFRelease(numberRef);   }   CFRelease(multiPhone); } //释放资源 //其他还有url，email，地址等等属性都是ABMutableMultiValueRef多值类型的，可以采用循环来遍历
