I'm trying to use delegate methods from NMSSH library in iOS but could not get it working. Let's take an example.
CustomViewController.h
#import <UIKit/UIKit.h>
#import <NMSSH/NMSSH.h>
#interface CustomViewController : UIViewController<NMSSHSessionDelegate, NMSSHChannelDelegate>
- (IBAction)connectButton:(UIButton *)sender;
#end
CustomViewController.m
#import "CustomViewController.h"
#implementation CustomViewController
-(void)viewDidLoad{
[super viewDidLoad];
}
- (IBAction)connectButton:(UIButton *)sender {
[self serverConnect:#"10.0.0.1"];
}
-(void)serverConnect:(NSString *)address{
NMSSHSession *session = [NMSSHSession connectToHost:address withUsername:#"username"];
NMSSHChannel *myChannel = [[NMSSHChannel alloc]init];
if (session.isConnected) {
[session authenticateByPassword:#"password"];
if (session.isAuthorized) {
NSLog(#"Authentication succeeded");
[session setDelegate:self];
[myChannel setDelegate:self];
}
}
NSError *error = nil;
//session.channel.requestPty = YES; (tried and later ignored)
NSString *response = [session.channel execute:#"mkdir" error:&error];
NSLog(#"Response from device: %#", response);
}
- (void)session:(NMSSHSession *)session didDisconnectWithError:(NSError *)error{
NSLog(#"log if session disconnects...Delegate method");
}
- (void)channel:(NMSSHChannel *)channel didReadError:(NSString *)error{
NSLog(#"Error received...Delegate method");
}
- (void)channel:(NMSSHChannel *)channel didReadRawData:(NSData *)data{
NSLog(#"Read Raw Data...Delegate method");
}
Connection to the server, sending a single line command and acknowledgement back from the server in Console is OK.
I have decent idea how to pass values from one View Controller to another using delegate (went through few tutorials with practical implementation).
With the same knowledge I am attempting to get response from delegate methods parts of NMSSH library but it's driving me round and round. I've found http://cocoadocs.org/docsets/NMSSH/2.2.1/ pretty nice API of this library but with my limited knowledge of iOS, I'm bit stuck.
Please help me.
My search finally came to an end with NMSSH AsyncAPI (branch) which supports multithreading.

I am currently serving videos in my iOS application with MPMoviePlayerController. The files are streamed from our backend server that requires authentication. It is key-based authenticated set in the Authorization HTTP Header.
It used to work perfectly with single video files. Now we’re trying to implement HLS adaptive streaming and we have faced a wall. I am currently using a custom NSURLProtocol subclass to catch requests made to our backend server and inject the proper Authorization header. For HLS it simply doesn’t work.
When we looked at the server logs, we clearly saw that the first request to the m3u8 file worked fine. Then all subsequent calls made (other m3u8 files and ts also) are 403 forbidden. It seems that MPMoviePlayerController doesn’t use NSURLProtocol for the other files. (side note: It does work on the simulator thought, but not on a physical device which let me think that both are not implemented in the same way).
MPMoviePlayerController instantiation
self.videoController = [[MPMoviePlayerController alloc] initWithContentURL:video.videoURL];
The URL Protocol interception
+ (NSURLRequest *) canonicalRequestForRequest:(NSURLRequest *)request {
NSMutableURLRequest *newRequest = request.mutableCopy;
[newRequest setValue:#"HIDDEN" forHTTPHeaderField:#"Authorization"];
return newRequest;
}
Any Ideas, suggestions, work arounds?
After verification with Apple Developer Technical Support, I figured what I wanted to achieve is impossible (and unsupported).
Here's the quote from the reply :
The problem you're seeing with NSURLProtocol and so on is that the movie playback subsystem does not run its HTTP requests within your process. Rather, these requests are run from within a separate system process, mediaserverd. Thus, all your efforts to affect the behaviour of that playback are futile.
By using NSURLProtocol, you can intercept the communication between MPMoviePlayerController and the streamed requests. To inject cookies along the way, or possibly save the stream offline videos. To do this, you should to create a new class extending NSURLProtocol:
Hope this helps you:
GAURLProtocol.h
#import <Foundation/Foundation.h>
#interface GAURLProtocol : NSURLProtocol
+ (void) register;
+ (void) injectURL:(NSString*) urlString cookie:(NSString*)cookie;
#end
GAURLProtocol.m
#import "GAURLProtocol.h"
#interface GAURLProtocol() <NSURLConnectionDelegate> {
NSMutableURLRequest* myRequest;
NSURLConnection * connection;
}
#end
static NSString* injectedURL = nil;
static NSString* myCookie = nil;
#implementation GAURLProtocol
+ (void) register
{
[NSURLProtocol registerClass:[self class]];
}
// public static function to call when injecting a cookie
+ (void) injectURL:(NSString*) urlString cookie:(NSString*)cookie
{
injectedURL = urlString;
myCookie = cookie;
}
+ (BOOL)canInitWithRequest:(NSURLRequest *)request {
if([[[request allHTTPHeaderFields] objectForKey:#"Heeehey"] isEqualToString:#"Huuu"])
{
return NO;
}
return [[[request URL] absoluteString] isEqualToString:injectedURL];
}
+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request {
return request;
}
// intercept the request and handle it yourself
- (id)initWithRequest:(NSURLRequest *)request cachedResponse:(NSCachedURLResponse *)cachedResponse client:(id<NSURLProtocolClient>)client {
if (self = [super initWithRequest:request cachedResponse:cachedResponse client:client]) {
myRequest = request.mutableCopy;
[myRequest setValue:#"Huuu" forHTTPHeaderField:#"Heeehey"]; // add your own signature to the request
}
return self;
}
// load the request
- (void)startLoading {
// inject your cookie
[myRequest setValue:myCookie forHTTPHeaderField:#"Cookie"];
connection = [[NSURLConnection alloc] initWithRequest:myRequest delegate:self];
}
// overload didReceive data
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[[self client] URLProtocol:self didLoadData:data];
}
// overload didReceiveResponse
- (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse *)response {
[[self client] URLProtocol:self didReceiveResponse:response cacheStoragePolicy:[myRequest cachePolicy]];
}
// overload didFinishLoading
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[[self client] URLProtocolDidFinishLoading:self];
}
// overload didFail
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[[self client] URLProtocol:self didFailWithError:error];
}
// handle load cancelation
- (void)stopLoading {
[connection cancel];
}
#end
Register
// register protocol
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[NSURLProtocol registerClass:[GAURLProtocol class]];
return YES;
}
Usage
[GAURLProtocol injectURL:#"http://example.com/video.mp4" cookie:#"cookie=f23r3121"];
MPMoviePlayerController * moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:#"http://example.com/video.mp4"];
[moviePlayer play];
#Marc-Alexandre Bérubé I can think of below workaround:
Run a proxy server in your app to proxy all the video URL's. Download all the video content by injecting the necessary auth headers to the request and relay back the content via the proxy server to the media player to render it. This approach may not work for large videos as the video rendering would only start after entire video is downloaded.
I have multiple views where I need to handle the network connection of socket.io, so I created singleton class namely MC_SocketHandler. Below is the code of the MC_SocketHandler class.
// MC_SocketHandler.h
#import <Foundation/Foundation.h>
#import "SocketIO.h"
#interface MC_SocketHandler : NSObject <SocketIODelegate>
// SocketIO
//#property (nonatomic) SocketIO *socketConnection;
+ (MC_SocketHandler *) sharedSocketHanderObj;
+ (SocketIO *) initHandShake;
+ (SocketIO *) getSocketConnection;
-(bool) isConnected;
-(void) disConnect;
-(void) fireAgentLeftChat;
#end
// MC_SocketHandler.m
#import "MC_SocketHandler.h"
#import "MC_APIUtility.h"
#implementation MC_SocketHandler
SocketIO *socketConnection = nil;
static MC_SocketHandler *sharedSocketObj = nil;
+ (MC_SocketHandler *) sharedSocketHanderObj {
if (sharedSocketObj == nil)
sharedSocketObj = [[MC_SocketHandler alloc] init];
return sharedSocketObj;
}
+(SocketIO*) initHandShake {
if (socketConnection == nil) {
NSDictionary *headers = [NSDictionary dictionaryWithObjectsAndKeys:[MC_APIUtility getApiToken], #"token", nil];
socketConnection = [[SocketIO alloc] initWithDelegate:(id)self ];
[socketConnection connectToHost:domain onPort:447 withParams:headers];
}
return socketConnection;
}
+ (SocketIO *) getSocketConnection {
return socketConnection;
}
-(bool) isConnected {
if (socketConnection == nil)
return socketConnection.isConnected;
return false;
}
-(void) disConnect {
if (socketConnection != nil && socketConnection.isConnected)
[socketConnection disconnect];
NSLog(#"Disconnected --- %hhd", socketConnection.isConnected );
return;
}
// SocketIO Delegate
-(void) socketIODidConnect:(SocketIO *)socket {
NSLog(#"Socket has Connected....");
}
-(void) socketIO:(SocketIO *)socket didReceiveEvent:(SocketIOPacket *)packet {
NSString *data = packet.data;
NSLog(#"---- didReceoveEvent - data - %#", data);
// Grab data from packet
NSDictionary *dict = packet.dataAsJSON;
NSLog(#"EVENT DATA :- %# DICT :- %#", data, dict);
/*
EVENTS To Listen
onSuccessInit
visitor_info
new_visitor
agent_online

*/
dict = nil;
// Pull out args fro mdict
//NSArray *args = dict[#"args"];
}
-(void) socketIO:(SocketIO *)socket didReceiveMessage:(SocketIOPacket *)packet {
NSLog(#"Rcvd Message - %#", packet.data);
}
-(void) socketIO:(SocketIO *)socket didSendMessage:(SocketIOPacket *)packet {
NSLog(#"Send Msg - %#", packet.dataAsJSON);
}
-(void) socketIO:(SocketIO *)socket onError:(NSError *)error {
NSLog(#"Error - %#", error);
}
-(void) socketIODidDisconnect:(SocketIO *)socket disconnectedWithError:(NSError *)error {
NSLog(#"Disconnected With Error - %#", error);
}
-(void) fireAgentLeftChat {
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:[MainAppDataObject sharedAppDataObject].activeAgentChatItem.chatSessionId forKey:#"chat_session_id"];
[socketConnection sendEvent:#"agentLeftChat" withData:dict];
return;
}
- (void)dealloc {
socketConnection = nil;
}
#end
Code that I use it in 1 of my views :
// Init SocketIO
SocketIO *socket = [MC_SocketHandler initHandShake];
// Fire Agent Online event
[socket sendEvent:#"setAgentOnline" withData:nil];
Handshake is being done properly, setAgentOnline event is send properly. Other events that I fire are also done properly. BUT,
when socket gets connected thru initHandshake, I believe "Socket has Connected...." should be seen in logs as that is written in socketIODidConnect delegate method. Similarly, I receive event (I see logs of socket.m class), but my delegate method didReceiveEvent is never called. Same way I don't see any logs of any delegate methods.
In initHandShake method only I have set the delegate also :
socketConnection = [[SocketIO alloc] initWithDelegate:(id)self ];
yet why these methods aren't called.
I was also wondering, when I receive events, on different events I got to perform different actions. How will I transfer to particular view (View's obj won't be shared with this to call his method) ? And If I create delegate, then I will have to handle all delegate methods in all views. What's will be the best method to work out with this ? And why this Singleton & delegate methods aren't being linked & called when I have set the delegate. Where am I going wrong ?
Any help, guidance is highly appreciative. Thanks alot.
In SocketIO, you create a SocketIO
Is that right?
In fact called "socketConnection". Am i right?
AT THAT TIME...
you must set the delegate !!!
Essentially, your code must look like this,
socketConnection = make one of these.
socketConnection.delegate = self;
It's possible this is your fundamental problem. I hope it helps!
PS you should, almost certainly, use only properties in iOS development. get rid of your "traditional" variables and use only properties.
I have a class, "WebAPI", that handles all web API calls, the class uses NSURLConnection through its asynchronous delegate-based calls.
Whenever an object needs to communicate with the web API it will use an instance of WebAPI and call the required method as shown below in the case of signing in I make the folowing call from the AppDelegate:
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
WebAPI *webAPI = [[WebAPI alloc] init];
[webAPI performLoginWithUserName:#"test1#myserver.com" andPassword:#"password"];
}
The problem is that once the performLoginWithUserName:andPassword call is made, the code progresses on and any/all response is received in the delegate methods that are implemented in WebAPI.m.
This is a real issue because I need to be able to get response codes and any data received within the class method from where the call to the WebAPI, originated . I would like to be able to this :
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
WebAPI *webAPI = [[WebAPI alloc] init];
WebAPIResponse * webAPIRespnse = [webAPI performLoginWithUserName:#"test1#myserver.com" andPassword:#"password"];
}
Where WebAPIResponse class is a custom class that will contain the HTTP Status code and any data that is received.
This is achievable if I change WebAPI.m to use NSURLConnection sendSynchronousRequest, but that doesnt enable me to receive all HTTP codes.
What would be the best way to fulfill this requirement?
Thank you for your help.
You could use blocks to handle responses.
For example:
WebApi.h
- (void)performLoginWithUsername:(NSString *)userName
andPassword:(NSString *)password
successBlock:(void(^)(NSData *response))successBlock
failureBlock:(void(^)(NSError *error))failureBlock;
WebApi.m
#interface WebAPI()
#property (nonatomic, copy) void(^authorizationSuccessBlock)(NSData *response);
#property (nonatomic, copy) void(^authorizationFailureBlock)(NSError *error);
#end
#implementation WebAPI
- (void)performLoginWithUsername:(NSString *)userName
andPassword:(NSString *)password
successBlock:(void(^)(NSData *response))successBlock
failureBlock:(void(^)(NSError *error))failureBlock {
self.authorizationSuccessBlock = successBlock;
self.authorizationFailureBlock = failureBlock;
// NSURLConnection call for authorization here
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
if (self.authorizationSuccessBlock != nil) {
self.authorizationSuccessBlock(data);
self.authorizationSuccessBlock = nil;
}
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
if (self.authorizationFailureBlock != nil) {
self.authorizationFailureBlock(error);
self.authorizationFailureBlock = nil;
}
}
AppDelegate.m
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
WebAPI *webAPI = [[WebAPI alloc] init];
[webAPI performLoginWithUserName:#"test1#myserver.com" andPassword:#"password" successBlock:^(NSData *response) {
// Handle result here
} failureBlock:^(NSError *error) {
// Handle error here
}];
}
Change your WebAPI class to provide a delegate interface of its own, or to use completion blocks on the request which are called when the asynchronous connection completes.
I am building an app that uses a web service and to get information from that web service I use NSURLSession and NSURLSessionDataTask.
I am now in the memory testing phase and I have found that NSURLSession is causing memory leaks.
This is not all of the leaks. It is all that I could fit in the picture.
Below is how I setup the NSURLSession and request the information from the web service.

Question:
Why is NSURLSession causing these memory leaks? I am invalidating the NSURLSession when I am finished with it. I am also releasing any properties that I do not need and setting the session to nil (refer to - (void)cleanupSession & - (void) endSessionAndCancelTasks).
Other Information:
The memory leaks occur after the session has completed and "cleaned up". Sometimes, they also occur after I have popped the UIViewController. But, all of my custom (GPPhotoRequest and GPSearch) objects and UIViewController are being dealloced (I've made sure by adding an NSLog).
I tried not to post to much code, but I felt like most of it needed to be seen.
Please let me know if you need any more information. Help is greatly appreciated.
I had this same "leaky", memory management issue when I switched to NSURLSession. For me, after creating a session and resuming/starting a dataTask, I was never telling the session to clean itself up (i.e. release the memory allocated to it).
// Ending my request method with only the following line causes memory leaks
[dataTask resume];
// Adding this line fixed my memory management issues
[session finishTasksAndInvalidate];
From the docs:
After the last task finishes and the session makes the last delegate call, references to the delegate and callback objects are broken.
Cleaning up my sessions fixed the memory leaks being reported via Instruments.
After rereading the URL Loading System Programming Guide it turns that I was setting the NSURLSession property to nil too early.
Instead, I need to set the NSURLSession property to nil AFTER I receive the delegate message URLSession:(NSURLSession *)session didBecomeInvalidWithError:(NSError *)error, which makes sense. Luckily, it was a minor mistake.
E.g.
- (void)URLSession:(NSURLSession *)session didBecomeInvalidWithError:(NSError *)error
{
if (error)
{
#ifdef DEBUG
NSLog(#"[GPPhotoRequest] Session Invalidation: %#", [error description]);
#endif
}
if ([session isEqual:_session])
{
[self cleanupSession];
}
}
Had the same issue. The #Jonathan's answer didn't make a sense - my app still leaked memory. I found out that setting the session property to nil in URLSession:didBecomeInvalidWithError: delegate method is causing the issue. Tried to look deeper into the URL Loading System Programming Guide. It says
After invalidating the session, when all outstanding tasks have been canceled or have finished, the session sends the delegate a URLSession:didBecomeInvalidWithError: message. When that delegate method returns, the session disposes of its strong reference to the delegate.
I left the delegate method blank. But the invalidated session property still have a pointer, when should I set it nil? I just set this property weak
// .h-file
#interface MyClass : NSObject <NSURLSessionDelegate>
{
__weak NSURLSession *_session;
}
// .m-file
- (NSURLSessionTask *)taskForRequest:(NSURLRequest *)request withCompletionHandler:(void(^)(NSData *,NSURLResponse *,NSError *))handler
{
if(!_session)
[self initSession];
//...
}
The app stopped leaking memory.
Please see my answer here: https://stackoverflow.com/a/53428913/4437636
I believe this leak is the same one I was seeing, and only happens when running network traffic through a proxy. My code was fine, but it turned out that an internal bug in the Apple API was causing the leak.
i'm trying to get data from Google Analytics, using the Core Reporting API sdk.
https://developers.google.com/analytics/devguides/reporting/core/v3/gdataLibraries
But even the samples for IOS are not compiling on Xcode 5, and i cannot find any source code or exemple.
Sorry to ask for that, but is there anyone have a link to a demo, or tutorial to get this done?
There is a bug reported under analytics-issues
a linker error when building with Xcode 5
it has fixed status as for 20 Sep 2013. And project manager has also given a link to IOS SDK where is should work with version > 3.01.
But after this fixed status - there are three users as for today who have the problem.
After a lot of try, i put a small sample of how to get data, if this can help someone:
