关于iOS udp 通信的问题

Question

说明一下：
[self scheduleDequeueReceive];
和
- (void)scheduleDequeueReceive方法都是
AsyncUdpSocket.m文件中的

Answer 1

把-(BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port里面的代码贴出来看看再说。你那个错误是使用了已经被释放的内存。别人的库不存在这样的问题，你没改里面的代码的话，就不用把别人库里面的代码帖出来了。

Answer 2

-(BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port
{
    NSLog(@"received data: %@",[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]);
    NSLog(@"%@",host);
    if(tag==1)
    {
        if([[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease] compare:@"ihd"])
        {
            hostIP=[[NSString alloc] initWithString:host];
            //[udpSocket close];
        }
    }
    if(tag==sn)
    {
        //先测试是否能够获取到指定的数据流
        NSLog(@"received data: %@",[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]);
    }
    
    
    return YES;
}

Answer 3

整个socket的创建及调用部分：
self.udpSocket=[[AsyncUdpSocket alloc] initWithDelegate:self];
[udpSocket bindToPort:8001 error:&error];    
[udpSocket enableBroadcast:YES error:&error]; 
[udpSocket joinMulticastGroup:@"224.0.0.1" error:&error];
[udpSocket receiveWithTimeout:-1 tag:1];
接收部分：
-(BOOL)onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:(NSData *)data withTag:(long)tag fromHost:(NSString *)host port:(UInt16)port
{
    NSLog(@"received data: %@",[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]);
    NSLog(@"%@",host);
    if(tag==1)
    {
        if([[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease] compare:@"ihd"])
        {
            hostIP=[[NSString alloc] initWithString:host];
            //[udpSocket close];
        }
    }
    if(tag==sn)
    {
        //先测试是否能够获取到指定的数据流
        NSLog(@"received data: %@",[[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease]);
    }
    
    
    return YES;
}请帮忙看看

Answer 4

把  [udpSocket setRunLoopModes:[NSArray arrayWithObject:NSRunLoopCommonModes]];添加到self.udpSocket=[[AsyncUdpSocket alloc] initWithDelegate:self];后面试试
