Buffering NSOutputStream used as NSInputStream?

Question

I have this consumer class that takes an NSInputStream as argument which will be processed async, and I want to push data that comes from a producer class that requires that

Answer 1

Here is an already implemented class that does exactly what you want

BufferOutputStreamToInputStream

// initialize
self.bufferWriter = [[BufferOutputStreamToInputStream alloc] init];
[self.bufferWriter openOutputStream];

// later you want to set the delegate of the inputStream and shedule it in runloop
// remember, you are responsible for the inputStream, the outputStream is taken care off;)
self.bufferWriter.inputStream.delegate = self;
[self.bufferWriter.inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[self.bufferWriter.inputStream open]

// fill with data when desired on some event      
[self.bufferWriter addDataToBuffer:someData];
