我正在使用专为iPhone直播而制作的私有(private)图书馆。在每次记录每一帧时，它都会调用一个delegate函数voidMyAQInputCallback(void*inUserData,AudioQueueRefinQueue,AudioQueueBufferRefinBuffer,constAudioTimeStamp*inStartTime,UInt32inNumPackets,constAudioStreamPacketDescription*inPacketDesc);NowhowIcanappendthisinBuffertomyAVAssetWriterInpu

我想从iPhone连接Alexa，因为我正在使用一个在Github上用swift2.2编写的示例所以我需要将其转换为Swift3.0从xcode从Swift2.2迁移到Swift3.0已完成，解决了几乎所有错误，现在唯一剩下的错误与AudioQueueBufferRef有关swift2.2:self.recorderState=RecorderState(setupComplete:false,dataFormat:AudioStreamBasicDescription(),queue:UnsafeMutablePointer.alloc(1),buffers:Array(count:

如何在Swift中传递C回调？考虑这个例子:classAudioQueue{vardesc:AudioStreamBasicDescriptionvarqueue:AudioQueue?funcaudioQueueHandleBuffer(ctx:UnsafeMutablePointer,inAQ:AudioQueue!,inBuffer:AudioQueueBufferRef){//dostuff}funcinitialize(){//thisdoesnotwork!varerr=AudioQueueNewOutput(&desc,audioQueueHandleBuffer,nil
