1.错误码57和错误码32
Error Domain=NSPOSIXErrorDomain Code=57"Socket is not connected" UserInfo={NSLocalizedDescription=Socket isnot connected}
send error: Error Domain=NSPOSIXErrorDomain Code=32 "Broken pipe"
UserInfo={NSLocalizedDescription=Broken pipe}
解决办法：重新初始化socket
- (void)onUdpSocket:(AsyncUdpSocket*)sock didNotReceiveDataWithTag:(long)tag dueToError:(NSError*)error {
NSLog(@"receive error:%@ ",error.description);
//receive error: Error Domain=NSPOSIXErrorDomain Code=57 "Socket is not connected" UserInfo={NSLocaliz
if(error.code==57) {
NSLog(@"sendSocket = %@;;; recSocket = %@;;; sock = %@",self.sendSocket,self.recSocket,sock);
self.isConnect=NO;
self.currentMojing=nil;
[self.mojingIPsList removeAllObjects];
self.count=self.mojingIPsList.count;
[self.recSocket close];
self.recSocket=nil;
[self.sendSocket close];
self.sendSocket=nil;
[self setup];
}
}
- (void)setup{
self.sendSocket= [[AsyncUdpSocket alloc]init];
self.sendSocket.delegate=self;
self.recSocket= [[AsyncUdpSocket alloc]init];
self.recSocket.delegate=self;
NSError* error =nil;
//设置其可以接收广播
//[self.recSocket enableBroadcast:YES error:&error];
//接收时只bind端口
if(![self.recSocketbindToPort:SERIVE_RECEIVE_PORTerror:&error]) {

return;
}
//加入组播
[self.recSocket joinMulticastGroup:SERIVE_MulticastGroup_IP error:nil];
