我正在尝试使用GCDAsyncSocket该类连接到设备，但遇到了问题。它似乎没有通知我它是否连接，但也没有通知我它未能连接。

这是我的 .h 文件

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

@interface SocketTestClass : NSObject <GCDAsyncSocketDelegate>
{
    GCDAsyncSocket* socket;
}

@end

这是我的 .m 文件

@implementation SocketTestClass

- (void)dealloc
{
    [self disconnect];
}

- (void)connect
{
    NSLog(@"Ready to create socket");

    socket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:dispatch_get_main_queue()];

    NSError* error = Nil;
    if (![socket connectToHost:@"192.168.1.200" onPort:80 withTimeout:10 error:&error])
    {
        NSLog(@"Failed to create socket");
    }
}

- (void)disconnect
{
    if ([socket isConnected])
    {
        [socket disconnect];
    }
}

- (void)socket:(GCDAsyncSocket *)sock
didAcceptNewSocket:(GCDAsyncSocket *)newSocket
{
    NSLog(@"Socket did accept new socket");
}

- (void)socket:(GCDAsyncSocket *)sock
didConnectToHost:(NSString *)host
          port:(uint16_t)port
{
    NSLog(@"Socket did connect to host on port");
}

- (void)socket:(GCDAsyncSocket *)sock
   didReadData:(NSData *)data
       withTag:(long)tag
{
    NSLog(@"Socket did read data with tag");
}

- (void)socket:(GCDAsyncSocket *)sock
didReadPartialDataOfLength:(NSUInteger)partialLength
           tag:(long)tag
{
    NSLog(@"Socket did read partial data of length");
}

- (void)socket:(GCDAsyncSocket *)sock didWriteDataWithTag:(long)tag
{
    NSLog(@"Socket did write data with tag");
}

- (void)socket:(GCDAsyncSocket *)sock
didWritePartialDataOfLength:(NSUInteger)partialLength
           tag:(long)tag
{
    NSLog(@"Socket did write partial data of length");
}

- (void)socketDidCloseReadStream:(GCDAsyncSocket *)sock
{
    NSLog(@"Socket did close read stream");
}

- (void)socketDidDisconnect:(GCDAsyncSocket *)sock
                  withError:(NSError *)err
{
    NSLog(@"Socket did disconnect with error");
}

- (void)socketDidSecure:(GCDAsyncSocket *)sock
{
    NSLog(@"Socket did secure");
}

@end

从我的视图控制器中，我调用了这个类的 connect 方法，但唯一打印到控制台的是：

Ready to create socket

注意：我已经为控制台实现了所有委托，GCDAsyncSocket并通过NSLog.

关于为什么我没有收到消息“Socket did connect to host on port”或消息“Socket did disconnect with error”的任何想法？
