iOS how can i perform multiple NSInputStream

由 你说的曾经没有我的故事 提交于 2021-02-08 08:05:57
问题 My app uses NSInputStream like below: inputStream.delegate = self; [inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [readStream open]; and delegate: - (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent It works fine, but all other requests that i do, it queued until first is finished. I can do one per time and there is no way to do multiple concurrent requests. There is a solution ? Thank you This solution not work for me : https:

问题 I have a large sized video saved in my documents directory. I want to retrieve this video and remove it's first 5 bytes. For large video files of above 300 MB using [NSData(contentsOf: videoURL)] causing Memory issue error. I have gone through Swift: Loading a large video file (over 700MB) into memory and found that we need to use [InputStream] and [OutputStream] or [NSFileHandle]for large files. How to use it? Sample code is given below: let nsDocumentDirectory = FileManager

iOS input stream receives fast data only if output stream is simultaneously sending

问题 My iOS app requires socket communication. I'm following this Ray Wenderlich tutorial for setting up the input and output streams. The server I'm using is Twisted. My app requires sending and receiving fast bursts of data generated by external events like gyroscope data. It is sending/receiving data in form of JSON string. So largely, it's very much like a real-time messaging chat app but sending and receiving is very fast and in bursts. So my app layout is that I have 1 view controller:

Using NSOutputStream to POST to url

由 一笑奈何 提交于 2019-12-21 06:24:47
问题 So all I want to do is send a POST request to a url. Now I tried using NSURLRequest/NSURLConnection, but was having problems with that and decided to move to a lower level, also because I want to send large files and thought dealing directly with streams might be better. But the output stream delegate never seems to be called, and I can't seem to find examples using NSOutputStream's initWithURL . NSURL *url = [NSURL URLWithString:NSString stringWithFormat: @"http://url"]; self.outputStream =

Writes to NSOutputStream after performing work on background thread don't work

问题 I have a program that is sending large files over NSStreams after some initial processing. The flow of the application goes like this: 1) Two devices connect to each other, open their input and output streams, and schedule their run loops: [self.inputStream setDelegate:self]; [self.outputStream setDelegate:self]; [self.inputStream scheduleInRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode]; [self.outputStream scheduleInRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode];

问题 Okay so I'm implementing a NSOutput and Input Streams. When they are initialized, the streams open and connect to my TCPServer I have running on my PC, but then appear to close once outside of the initializing function or maybe the streams aren't being stored properly. I'm not quite sure so any assistance is greatly appreciated In my .h file: @interface AVCamViewController : UIViewController <UIImagePickerControllerDelegate,UINavigationControllerDelegate, NSStreamDelegate> { NSOutputStream

Sending UIImage over NSOutputStream [closed]

I'm trying to send an image that user takes to the server. I get the JPEG representation, append that to the string needed to upload the photo, and then send the data through NSOutputStream. However, when I try to get the photo back from server, I only see 10% of it from the top. Any help would be appreciated. btw. socket is open and connected. Here's my code: NSString *requestString = [NSString stringWithFormat:@"SubmitPhoto::%@::", userID]; NSData * stringData = [requestString dataUsingEncoding:NSUTF8StringEncoding]; NSData *imgData = UIImageJPEGRepresentation(image, 1.0); NSMutableData
