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
