oc中，我用GCDAsyncSocket连上了socket，但是无法往服务器发送数据

Question

#import "GCDSocketManager.h"
#import "GCDAsyncSocket.h"

#define SocketHost @"61.191.45.94"
#define SocketPort 8091

@interface GCDSocketManager()

//握手次数
@property(nonatomic,assign) NSInteger pushCount;

//断开重连定时器
@property(nonatomic,strong) NSTimer *timer;

//重连次数
@property(nonatomic,assign) NSInteger reconnectCount;

@end

@implementation GCDSocketManager

//全局访问点

• (instancetype)sharedSocketManager { static GCDSocketManager *_instance = nil; static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{ _instance = [[self alloc] init]; }); return _instance; }

//可以在这里做一些初始化操作

• (instancetype)init
  {
  self == [super init];
  if (self) {
  self.socket = [[GCDAsyncSocket alloc]initWithDelegate:self delegateQueue:dispatch_get_main_queue()];

  }
  return self;
  }

#pragma mark 请求连接
//连接

• (void)connectToServer {
  self.pushCount = 0;

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

  NSError *error = nil;
  // [self.socket connectToHost:SocketHost onPort:SocketPort error:&error];
  [self.socket connectToHost:SocketHost onPort:SocketPort error:&error];
  if (error) {
  NSLog(@"SocketConnectError:%@",error);
  }
  }

#pragma mark 连接成功
//连接成功的回调

• (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(uint16_t)port {
  NSLog(@"socket连接成功");

  [self sendDataToServer];
  }

//连接成功后向服务器发送数据

  NSData *cmdData = [jsonData dataUsingEncoding:NSUTF8StringEncoding];
  NSLog(@"socket发送数据--->%@",cmdData);
  //发送
  [self.socket writeData:cmdData withTimeout:-1 tag:0];

  //读取数据
  [self.socket readDataWithTimeout:-1 tag:100];
  }

//连接成功向服务器发送数据后,服务器会有响应

• (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag {
  NSString *msg = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

  NSLog(@"收到的数据-->%@",msg);
  [self.socket readDataWithTimeout:-1 tag:200];

  //服务器推送次数
  self.pushCount++;

  //在这里进行校验操作,情况分为成功和失败两种,成功的操作一般都是拉取数据
  }

#pragma mark 连接失败
//连接失败的回调

• (void)socketDidDisconnect:(GCDAsyncSocket *)sock withError:(NSError *)err {
  NSLog(@"Socket连接失败");

  self.pushCount = 0;

  NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];

  NSString *currentStatu = [userDefaults valueForKey:@"Statu"];

  //程序在前台才进行重连
  if ([currentStatu isEqualToString:@"foreground"]) {

  //重连次数
  self.reconnectCount++;
  
  //如果连接失败 累加1秒重新连接 减少服务器压力
  NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:1.0 * self.reconnectCount target:self selector:@selector(reconnectServer) userInfo:nil repeats:NO];
  
  self.timer = timer;
  

  }
  }

//如果连接失败,5秒后重新连接

• (void)reconnectServer {

  self.pushCount = 0;

  self.reconnectCount = 0;

  //连接失败重新连接
  NSError *error = nil;
  [self.socket connectToHost:SocketHost onPort:SocketPort error:&error];
  if (error) {
  NSLog(@"SocektConnectError:%@",error);
  }
  }

#pragma mark 断开连接
//切断连接

• (void)cutOffSocket {
  NSLog(@"socket断开连接");

  self.pushCount = 0;

  self.reconnectCount = 0;

  [self.timer invalidate];
  self.timer = nil;

  [self.socket disconnect];
  }
  @end

sendDataToServer中我调用writeData给服务器发送数据无法发送

把tag都改成一致再试试
