Body
I have managed to send and receive NSData from one iPhone to Another using Bonjour. I have wrote callbacks for recording audio using Audio Queue and sent the NSData using the following callback on the sender side: <pre><code> void AudioInputCallback(void * inUserData, AudioQueueRef inAQ, AudioQueueBufferRef inBuffer, const AudioTimeStamp * inStartTime, UInt32 inNumberPacketDescriptions, const AudioStreamPacketDescription * inPacketDescs) { RecordState * recordState = (RecordState*)inUserData; if (!recordState->recording) { printf("Not recording, returning\n"); } // if (inNumberPacketDescriptions == 0 && recordState->dataFormat.mBytesPerPacket != 0) // { // inNumberPacketDescriptions = inBuffer->mAudioDataByteSize / recordState->dataFormat.mBytesPerPacket; // } printf("Writing buffer %lld\n", recordState->currentPacket); OSStatus status = AudioFileWritePackets(recordState->audioFile, false, inBuffer->mAudioDataByteSize, inPacketDescs, recordState->currentPacket, &inNumberPacketDescriptions, inBuffer->mAudioData); NSLog(@"DATA = %@",[NSData dataWithBytes:inBuffer->mAudioData length:inBuffer->mAudioDataByteSize]); [[NSNotificationCenter defaultCenter] postNotificationName:@"Recording" object:[NSData dataWithBytes:inBuffer->mAudioData length:inBuffer->mAudioDataByteSize]]; if (status == 0) { recordState->currentPacket += inNumberPacketDescriptions; } AudioQueueEnqueueBuffer(recordState->queue, inBuffer, 0, NULL); } </code></pre> In the above code I have managed to send the inBuffer->mAudioData converted to NSData and send it on the other iPhone. I have also received the same data on the receiver iPhone. But now I do not know how to read this NSData. How to convert this data into an audio format and listen this audio on the speaker. Do I need to use Audio Queues on the receiver side or do I use simple AVPlayer to listen to the sound. If anyone can help solve it would be a great help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
