Hello Ebrahim,

I added this code to the sample I've provided you through support, and it works without problems. I can send the updated code to you again via support.

My advice is to check for memory management issues in your code, e.g.: check if you retained correctly the objects you are using, like the connectionInfo.

Hope this helps.
Best regards,

Gianluca
Hello Gianluca,
My Code is :
- (void)connectWithLightStreamer
{

fieldNames = [ NSArrayarrayWithObjects :LIGHTSTREAMER_FIELDNAMES, nil];
[ selfperformSelectorInBackground: @selector(connectInBackground) withObject:nil];

}
- (void) connectInBackground
{
_client = [[ LSClient alloc ]init ];
LSConnectionInfo *connectioninfo = [LSConnectionInfoconnectionInfoWithPushServerURL : LIGHTSTREAMER_CONNECITON_ADDRESSpushServerControlURL : niluser :@"username" password:@"password" adapter:LIGHTSTREAMER_CONNECITON_ADAPTER];
[ _clientopenConnectionWithInfo:connectioninfo delegate:self];
}
- (void) clientConnection :Smile_Ac: LSClient*)client didReceiveServerFailure :Smile_Ac: LSPushServerException *)failure {


[ _clientperformSelectorInBackground: @selector(closeConnection) withObject:nil];

}

but i receive error : Thread 8:signal SIGABRT
Hello Ebrahim,

to trace this problem I will need full logs and possibly a crash dump. You should add the following lines to your application:didFinishLaunchingWithOptions: delegate:

[ LSLogenableSourceType: LOG_SRC_CLIENT];
[ LSLogenableSourceType: LOG_SRC_SESSION];
[ LSLogenableSourceType :LOG_SRC_STATE_MACHINE];

Then run your app until you get the crash, save the crash dump and contact support sending both the crash dump and the logs the app has produced.

Thanks.
Best regards,

Gianluca

      Hello Ebrahim,

      it seems what you are experiencing is not a crash due to some sort of bug, but simply an uncaught exception. As stated in the LS client library documentation set, openConnectionWithInfomay raise two kind of exceptions (LSPushServerException and LSPushConnectionException) and thus you need a try/catch block, such as:

      @try {
      [_client openConnectionWithInfo:connectioninfo delegate:self];

      } @catch (NSException *e) {
      NSLog(@"Can't connect due to exception: %@", e);
      }

      Best regards,

      Gianluca
