nsstream

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'm using CFStream/NSStream to make http connections. I want to be able to detect that a SSL handshake fails for three cases: case A: server is not trusted case B: server is trusted but asks a client certificate case C: server is not trusted and it asks a client certificate Today without doing anithing on the SSL Properties of my CFStream, I get: case A: error -9807 case B: no error but server refuses the connection (error 500) case C: error 9807 Is there a way to configure CFStream to

问题 I am a newbie in Objective-C. I am trying to learn how to work with NSStream . I just used simple code from Apple Support. This code should open a stream from a file in my Desktop and show a simple message when the delegate is called by iStream. At the end of the code, I can see the status is correct, but the delegate never gets called. What am I missing? #import <Foundation/Foundation.h> @interface MyDelegate: NSStream <NSStreamDelegate>{ } - (void)stream:(NSStream *)stream handleEvent:

问题 I have written this code to setup a stream with a server: -(void)streamOpenWithIp:(NSString *)ip withPortNumber:(int)portNumber; { CFReadStreamRef readStream; CFWriteStreamRef writeStream; CFStreamCreatePairWithSocketToHost(kCFAllocatorDefault, (__bridge CFStringRef)ip, portNumber, &readStream, &writeStream); if(readStream && writeStream) { CFReadStreamSetProperty(readStream, kCFStreamPropertyShouldCloseNativeSocket, kCFBooleanTrue); CFWriteStreamSetProperty(writeStream,

问题 In my App, have setup the stream like this, (void)connectStream:(NSString *)pHostName PortNo:(int)inPortNo HasInput:(bool)bInput HasOutput:(bool)bOutput{ NSHost *host = [NSHost hostWithName:pHostName]; //host = [NSHost hostWithAddress:pHostName]; [NSStream getStreamsToHost:host port:inPortNo inputStream:&pInputStream outputStream:&pOutputStream]; [pInputStream retain]; [pOutputStream retain]; [pInputStream setDelegate:self]; [pOutputStream setDelegate:self]; bool bUseSSL = YES; if (bUseSSL) {

问题 I have an application set up to send data between two iOS devices using NSStream s over a TCP connection. The data sent consists of two parts: An integer indicating the size of the message object to come The message object, some NSStrings and an NSData object encoded with NSKeyedArchiver The issue: When the NSData object is around 1.5Mb, I get an incomprehensible archive exception when I try to decode it. When reading the 4 bytes following where the message should be, a large number is there,

问题 I am creating a multiplayer game using MPCF. You control a spacehip on the iPad using the iPhone. I am experiencing various amount of lag and latency and buffering/pauses at random times and intervals and have now landed on Apples Technical Q&A NW26 paper that talks about disabled the Nagle Algorithm. Im trying it out but my program keeps crashing and I dont understand why. It seem to be that CFWriteStreamCopyProperty always return NULL. - (void)stream:(NSStream *)stream handleEvent:

问题 I am using (and am required to use) a third-party framework to which I do not have source. The third-party framework handles creating an authenticated client/server connection and hands back a pair of open NSStreams. The challenge that I have is the NSStreams are scheduled on the main thread (creating situations where the UI may become unresponsive - which I would like to avoid). At the point that the streams are handed off from the third party framework, no network traffic is in progress. So

问题 I have the following situation where I create a GCD dispatch queue and in it I schedule an NSStream to the current NSRunLoop , as is required in its specification for it to emit delegate events, and then I make the run loop for that thread run using [[NSRunLoop currentRunLoop run] . This generates three possible scenarios: Create a serial queue in which an initial write message is sent through the stream and other write messages are only sent when there's a delegate callback from the NSStream
