昨天在os x上写了个网络通信的小程序http://blog.youkuaiyun.com/zj510/article/details/8934312，今天在iphone也试了一下。

使用了Cocoa中的NSStream.代码相当的简单。

- (void)Work_Thread:(NSURL *)url
{
    NSString* strHost = [url host];
    int port = [[url port] integerValue];
    
    [NSStream getStreamsToHostNamed:strHost port: port inputStream:&readStream outputStream:&writeStream];
    
    [readStream setProperty:NSStreamNetworkServiceTypeVoIP forKey:NSStreamNetworkServiceType];
    [readStream setDelegate:self];
    [readStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [readStream open];
    NSLog(@"VOIP stream, %x", readStream);
    
    [writeStream open];
    [writeStream write:"abcd" maxLength:4];
    

    NSInputStream* iStream;
    [NSStream getStreamsToHostNamed:strHost port:port inputStream:&iStream outputStream:nil];
    [iStream setDelegate: self];
    [iStream scheduleInRunLoop
