STOMP client for Objective-C

This is a simple STOMP client based on [https://github.com/juretta/objc-stomp] that supports Stomp v1.1 and v1.2.

Usage

This library was created to work with SocketRocket [https://github.com/square/SocketRocket]. But shoud work with others WebSocket Libraries.

CRVStompClient.{h,m} to your project.

MyExample.h

#import <Foundation/Foundation.h>

@class CRVStompClient;
@protocol CRVStompClientDelegate;


@interface MyExample : NSObject<CRVStompClientDelegate> {
    @private
    CRVStompClient *service;
}
@property(nonatomic, retain) CRVStompClient *service;

@end

In MyExample.m

#define kUsername   @"USERNAME"
#define kPassword   @"PASS"
#define kQueueName  @"/topic/systemMessagesTopic"

[...]

-(void) aMethod {
    CRVStompClient *s = [[CRVStompClient alloc] 
            initWithHost:@"localhost" 
                    port:61613 
                    login:kUsername
                passcode:kQueueName
                delegate:self];
    [s connect];


    NSDictionary *headers = [NSDictionary dictionaryWithObjectsAndKeys:     
            @"client", @"ack", 
            @"true", @"activemq.dispatchAsync",
            @"1", @"activemq.prefetchSize", nil];
    [s subscribeToDestination:kQueueName withHeader: headers];

    [self setService: s];
    [s release];
}

#pragma mark CRVStompClientDelegate
- (void)stompClientDidConnect:(CRVStompClient *)stompService {
        NSLog(@"stompServiceDidConnect");
}

- (void)stompClient:(CRVStompClient *)stompService messageReceived:(NSString *)body withHeader:(NSDictionary *)messageHeader {
    NSLog(@"gotMessage body: %@, header: %@", body, messageHeader);
    NSLog(@"Message ID: %@", [messageHeader valueForKey:@"message-id"]);
    // If we have successfully received the message ackknowledge it.
    [stompService ack: [messageHeader valueForKey:@"message-id"]];
}

- (void)dealloc {
    [service unsubscribeFromDestination: kQueueName];
    [service release];
    [super dealloc];
}
