Question

我想为iPhone实施一个Voip应用程序。

如何在使用套接字编程和流式传输的用户之间建立点对点连接。

任何可用的源代码。

Answer 1

尝试GCDAsyncSocket https://github.com/robbiehanson/CocoaAsyncSocket

或者你也可以尝试一下 http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-server

定义类属性：

NSInputStream *inputStream;
NSOutputStream *outputStream;

初始化你的溪流

CFReadStreamRef readStream;
CFWriteStreamRef writeStream;

CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)kScannerIP, kScannerPort, &readStream, &writeStream);
inputStream = (__bridge NSInputStream *)readStream;
outputStream = (__bridge NSOutputStream *)writeStream;

[inputStream setDelegate:self];
[outputStream setDelegate:self];

[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

[inputStream open];
[outputStream open];

实现委托方法来处理传入的数据：

- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent {
    switch (streamEvent) {
        case NSStreamEventOpenCompleted:
            break;

        case NSStreamEventHasBytesAvailable:
            break;

        case NSStreamEventHasSpaceAvailable:
            break;

        case NSStreamEventErrorOccurred:
            break;

        case NSStreamEventEndEncountered:
            break;

        default:
            NSLog(@"Unknown event");
    }
}

最后关闭你的网络：

[inputStream close];
[outputStream close];
[inputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream removeFromRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
inputStream = nil;
outputStream = nil;

你不能;当你的设备的IP都发生变化时（两者都转移到不同的网络）会发生什么？
