Category on socket.IO-objc to use block callbacks instead of delegate callbacks.

Adding SocketIO+Blocks to your project

From CocoaPods

Add pod 'SocketIOBlocks' to your Podfile.

Source files

Another way to add the SocketIO+Blocks to your project is to directly add the source files and resources to your project.

Download the latest code version or add the repository as a git submodule to your git-tracked project.
Open your project in Xcode, than drag and drop SocketIO+Blocks.h and SocketIO+Blocks.m files onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project.
Include SocketIO+Blocks wherever you need it with #import "SocketIO+Blocks.h".

Usage

To connect to your host simply write

SocketIO *socketIO = [[SocketIO alloc] initWithDelegate:nil];
[socketIO connectToHost:@"localhost" onPort:3000 withCallback:^(SocketIO *socketIO, NSError *error){
    NSLog(@"Socket %@ did connect with error %@", socket, error);
}];

If you need additional parameters you could use another methods

- (void)connectToHost:(NSString *)host onPort:(NSInteger)port withParams:(NSDictionary *)params withCallback:(void (^)(SocketIO *, NSError *))callback;
- (void)connectToHost:(NSString *)host onPort:(NSInteger)port withParams:(NSDictionary *)params withNamespace:(NSString *)endpoint withCallback:(void (^)(SocketIO *, NSError *))callback;

A delegate methods which response on error has been replaced by two methods. Key uses for support multiple error handlers

- (void)addErrorHandler:(void (^)(SocketIO *, NSError *))handler forKey:(NSString *)key;
- (void)removeErrorHandlerForKey:(NSString *)key

To handle received messages you can add handler for specific key too

- (void)addMessageHandler:(void (^)(SocketIO *, SocketIOPacket *))handler forKey:(NSString *)key;

If you no longer need message handler you can simply remove it from socket

- (void)removeMessageHandlerForKey:(NSString *)key;

The same logic applies for handle events and JSON objects.
