Question

我有多个视图，我需要处理socket.io的网络连接，所以我创建了单例类，即MC_SocketHandler。下面是MC_SocketHandler类的代码。

//    MC_SocketHandler.h

#import <Foundation/Foundation.h>
#import "SocketIO.h"


@interface MC_SocketHandler : NSObject <SocketIODelegate>

// SocketIO
//@property (nonatomic) SocketIO *socketConnection;

+ (MC_SocketHandler *) sharedSocketHanderObj;
+ (SocketIO *) initHandShake;
+ (SocketIO *) getSocketConnection;

-(bool) isConnected;
-(void) disConnect;
-(void) fireAgentLeftChat;

@end

//  MC_SocketHandler.m

#import "MC_SocketHandler.h"
#import "MC_APIUtility.h"

@implementation MC_SocketHandler

SocketIO *socketConnection = nil;
static MC_SocketHandler *sharedSocketObj = nil;

+ (MC_SocketHandler *) sharedSocketHanderObj {
    if (sharedSocketObj == nil)
        sharedSocketObj = [[MC_SocketHandler alloc] init];

    return sharedSocketObj;
}

+(SocketIO*) initHandShake {

    if (socketConnection == nil) {
        NSDictionary *headers = [NSDictionary dictionaryWithObjectsAndKeys:[MC_APIUtility getApiToken], @"token", nil];
        socketConnection = [[SocketIO alloc] initWithDelegate:(id)self ];
        [socketConnection connectToHost:domain onPort:447 withParams:headers];
    }
    return  socketConnection;
}

+ (SocketIO *) getSocketConnection {
    return socketConnection;
}

-(bool) isConnected {
    if (socketConnection == nil)
        return socketConnection.isConnected;

    return false;
}

-(void) disConnect {
    if (socketConnection != nil && socketConnection.isConnected)
        [socketConnection disconnect];

    NSLog(@"Disconnected --- %hhd", socketConnection.isConnected );
    return;
}


// SocketIO Delegate
-(void) socketIODidConnect:(SocketIO *)socket {
    NSLog(@"Socket has Connected....");
}

-(void) socketIO:(SocketIO *)socket didReceiveEvent:(SocketIOPacket *)packet {

    NSString *data = packet.data;
    NSLog(@"---- didReceoveEvent - data - %@", data);

    // Grab data from packet
    NSDictionary *dict = packet.dataAsJSON;
    NSLog(@"EVENT DATA :- %@   DICT :- %@", data, dict);

    /*
     EVENTS To Listen
     onSuccessInit
     visitor_info
     new_visitor
     agent_online
     agent_offline
     agent_logout

     */
    dict = nil;

    // Pull out args fro mdict
    //NSArray *args = dict[@"args"];
}

-(void) socketIO:(SocketIO *)socket didReceiveMessage:(SocketIOPacket *)packet {
    NSLog(@"Rcvd Message - %@", packet.data);
}

-(void) socketIO:(SocketIO *)socket didSendMessage:(SocketIOPacket *)packet {
    NSLog(@"Send Msg - %@", packet.dataAsJSON);
}

-(void) socketIO:(SocketIO *)socket onError:(NSError *)error {
    NSLog(@"Error - %@", error);
}

-(void) socketIODidDisconnect:(SocketIO *)socket disconnectedWithError:(NSError *)error {
    NSLog(@"Disconnected With Error - %@", error);
}

-(void) fireAgentLeftChat {

    NSMutableDictionary *dict = [NSMutableDictionary dictionary];
    [dict setObject:[MainAppDataObject sharedAppDataObject].activeAgentChatItem.chatSessionId forKey:@"chat_session_id"];


    [socketConnection sendEvent:@"agentLeftChat" withData:dict];

    return;
}

- (void)dealloc {
    socketConnection = nil;
}



@end

我在其中一个视图中使用它的代码：

// Init SocketIO

SocketIO * socket = [MC_SocketHandler initHandShake];

// Fire Agent Online event
[socket sendEvent:@"setAgentOnline" withData:nil];

握手正在正常进行，setAgentOnline事件正确发送。我开火的其他事件也正确完成。但，当socket通过initHandshake连接时，我相信“Socket has Connected ....”应该在日志中看到，因为它是用socketIODidConnect委托方法编写的。同样，我收到事件（我看到socket.m类的日志），但我的委托方法didReceiveEvent从未被调用。同样地，我没有看到任何委托方法的任何日志。在initHandShake方法中，我也设置了委托： socketConnection = [[SocketIO alloc] initWithDelegate：（id）self]; 但为什么不调用这些方法。

我也想知道，当我收到活动时，我会在不同的事件中执行不同的操作。我将如何转移到特定视图（View的obj不会与此共享以调用他的方法）？如果我创建委托，那么我将必须处理所有视图中的所有委托方法。解决这个问题的最佳方法是什么？为什么这个Singleton＆amp;委托方法没有被链接＆amp;在设置委托时调用。我哪里错了？

任何帮助，指导都非常感激。非常感谢。

Answer 1

在SocketIO中，您创建一个SocketIO

是吗？

实际上称为“socketConnection”。我是对的吗？

那时......

你必须设置代表!!!

基本上，您的代码必须如此，

socketConnection =  make one of these.
socketConnection.delegate = self;

这可能是你的根本问题。我希望它有所帮助！

PS你几乎肯定应该在iOS开发中仅使用属性。摆脱“传统”变量，只使用属性。

iOS Singleton，Delegate和SocketIO之间出了问题
