只提取使用相同的應用程序的手機聯繫人

Question

我正在開發一個應用程序，我想從iphone中的聯繫人列表中獲取正在使用相同應用程序的聯繫人。

怎麼辦？任何示例代碼或鏈接？

請幫幫我。

注意：我不想在我的ios應用程序中獲取所有聯繫人，我只想獲取正在使用相同應用程序的聯繫人。

Answer 1

它不可能沒有後臺列表中的聯繫人，你不能只在ios應用程序中執行。

Answer 2

導入通訊錄框架第一

然後調用這兩個函數

-(void)AddressBookFetch{ 
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus(); 
    if (status == kABAuthorizationStatusDenied || status == kABAuthorizationStatusRestricted) { 
     // if you got here, user had previously denied/revoked permission for your 
     // app to access the contacts, and all you can do is handle this gracefully, 
     // perhaps telling the user that they have to go to settings to grant access 
     // to contacts 
     [[[UIAlertView alloc] initWithTitle:nil message:@"This app requires access to your contacts to function properly. Please visit to the \"Privacy\" section in the iPhone Settings app." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show]; 
     return; 
    } 

    CFErrorRef error = NULL; 
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error); 
    if (!addressBook) { 
     NSLog(@"ABAddressBookCreateWithOptions error: %@", CFBridgingRelease(error)); 
     return; 
    } 

    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { 
      if (error) { 
       NSLog(@"ABAddressBookRequestAccessWithCompletion error: %@", CFBridgingRelease(error)); 
      } 

      if (granted) { 
       // if they gave you permission, then just carry on 

       [self listPeopleInAddressBook:addressBook]; 
      } else { 
       // however, if they didn't give you permission, handle it gracefully, for example... 

       dispatch_async(dispatch_get_main_queue(), ^{ 
        // BTW, this is not on the main thread, so dispatch UI updates back to the main queue 

        [[[UIAlertView alloc] initWithTitle:nil message:@"This app requires access to your contacts to function properly. Please visit to the \"Privacy\" section in the iPhone Settings app." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show]; 
       }); 
      } 
     CFRelease(addressBook); 
    }); 

} 

然後通過此功能

- (void)listPeopleInAddressBook:(ABAddressBookRef)addressBook 
{ 
    NSArray *allPeople = CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook)); 
    numberOfPeople = [allPeople count]; 

    for (NSInteger i = 0; i < numberOfPeople; i++) { 
     ABRecordRef person = (__bridge ABRecordRef)allPeople[i]; 

     NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty)); 
     NSString *lastName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty)); 
     NSLog(@"Name:%@ %@", firstName, lastName); 
     if (firstName==nil) { 
      firstName=@""; 
     } 

     [nm addObject:firstName]; 
     if (lastName==nil) { 
      lastName=@""; 
     } 
     [ttl addObject:lastName]; 


     ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty); 

     // CFIndex numberOfPhoneNumbers = ABMultiValueGetCount(phoneNumbers); 
     //for (CFIndex i = 0; i < numberOfPhoneNumbers; i++) { 
     NSString *phoneNumber = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, 0)); 
     NSLog(@" phone:%@", phoneNumber); 
     if (phoneNumber==nil) { 
      phoneNumber=@""; 
     } 
     [phn addObject:phoneNumber]; 
     // } 
     // CFRelease(phoneNumbers); 

     NSLog(@"============================================="); 
    } 
}
