CKMadridService is Apple's codename for the service used to send iMessages. It is available only in iOS 5 (see ChatKit.framework).

Creating and sending an iMessage with CKMadridService[edit source]

//Compose a message
CKMessageStandaloneComposition *composition = [CKMessageStandaloneComposition newCompositionForText:@"Test Message"];

//Get a reference to the shared conversation list
CKConversationList *conversationList = [CKConversationList sharedConversationList];

//Get a reference to the shared Madrid Service
CKMadridService *madridService = [CKMadridService sharedMadridService];

NSString *messageRecipient = @"+1234567890"; // This is the phone number or email of the message recipient

//Make a Conversation
CKSubConversation *conversation = [conversationList conversationForGroupID:messageRecipient create:YES service:madridService];

//Create a message
CKMadridMessage *message = [madridService newMessageWithComposition:composition forConversation:conversation];

[madridService sendMessage:message];

[message release];
[composition release];
  • Note that you are responsible for releasing the message and the composition, but not the conversation.
