Usage

Import:

#import "HYChannel.h"

Implement the following optional methods:

- (void)channelOpen:(HYChannel *)sender message:(NSString *)message;

- (void)channelClose:(HYChannel *)sender error:(HYChannelError *)error;

- (void)channelMessage:(HYChannel *)sender data:(HYChannelData *)data;

- (void)channelSignal:(HYChannel *)sender data:(HYChannelSignal)data;

Opening a channel:

HYChannel *channel = [[HYChannel alloc] init];
[channel setDelegate:self];
@try {
    [self.channel connect:@"yourdomain.hydna.net" mode:READWRITEEMIT token:@"optionaltoken"];
}
@catch (NSException *exception) {
    NSLog(@"Error: %@", exception.reason);
}

Sending some data:

[channel writeString:@"Hello World"];

Sending a signal:

[channel emitString:@"Hello Signal"];

Receiving data:

- (void)channelMessage:(HYChannel *)sender data:(HYChannelData *)data
{
    NSData *payload = [data content];
    if ([data isUtf8Content]) {
        NSString *message = [[NSString alloc] initWithData:payload encoding:NSUTF8StringEncoding];
        NSLog(@"%@", message);
        
    } else {
        NSLog(@"Binary data received");
    }
}

Receiving signals:

- (void)channelSignal:(HYChannel *)sender data:(HYChannelSignal *)data
{
    NSData *payload = [data content];
    if ([data isUtf8Content]) {
        NSString *message = [[NSString alloc] initWithData:payload encoding:NSUTF8StringEncoding];
        NSLog(@"%@", message);
    } else {
        NSLog(@"Binary data received");
    }
}

Handling close:

- (void)channelClose:(HYChannel *)sender error:(HYChannelError *)error
{
    if (error.wasDenied) {
        NSLog(@"Connection to hydna was denied: %@", error.reason);
    } else if(error.wasClean) {
        NSLog(@"Connection closed by user or behavior!");
    } else {
        NSLog(@"Error: %@", error.reason);
    }
}
