iOS: How to check if a stream connection is timed out - ios

Question

In my application I connect to a server using
- (void)connectToServerUsingCFStream:(NSString *) urlStr portNo: (uint) portNo
This function is called by another method
- (void)connectToServer:(NSString *)serverName onPort:(int)portNo
{
[self connectToServerUsingCFStream:serverName portNo:portNo];
while (!((iStream.streamStatus == 2) || (oStream.streamStatus == 2))) {
continue;
}
NSLog(#"Streams connected");
[self sendLoginRequest];
}
Now I want to know wether there is an easy possibility to check if my connection request is timed out (maybe with a certain time value?). Is there a way to handle this in my while loop or should I use something different?
Thanks in advance,

I have no idea how you exactly implement the connection, but here I have some connection codes from the XMPPFramework , as the code comments:
/**
* XMPPReconnect handles automatically reconnecting to the xmpp server due to accidental disconnections.
* That is, a disconnection that is not the result of calling disconnect on the xmpp stream.
*
* Accidental disconnections may happen for a variety of reasons.
* The most common are general connectivity issues such as disconnection from a WiFi access point.
*
* However, there are several of issues that occasionaly occur.
* There are some routers on the market that disconnect TCP streams after a period of inactivity.
* In addition to this, there have been iPhone revisions where the OS networking stack would pull the same crap.
* These issue have been largely overcome due to the keepalive implementation in XMPPStream.
*
* Regardless of how the disconnect happens, the XMPPReconnect class can help to automatically re-establish
* the xmpp stream so as to have minimum impact on the user (and hopefully they don't even notice).
*
* Once a stream has been opened and authenticated, this class will detect any accidental disconnections.
* If one occurs, an attempt will be made to automatically reconnect after a short delay.
* This delay is configurable via the reconnectDelay property.
* At the same time the class will begin monitoring the network for reachability changes.
* When the reachability of the xmpp host has changed, a reconnect may be tried again.
* In addition to all this, a timer may optionally be used to attempt a reconnect periodically.
* The timer is started if the initial reconnect fails.
* This reconnect timer is fully configurable (may be enabled/disabled, and it's timeout may be changed).
*
* In all cases, prior to attempting a reconnect,
* this class will invoke the shouldAttemptAutoReconnect delegate method.
* The delegate may use this opportunity to optionally decline the auto reconnect attempt.
*
* Auto reconnect may be disabled at any time via the autoReconnect property.
*
* Note that auto reconnect will only occur for a stream that has been opened and authenticated.
* So it will do nothing, for example, if there is no internet connectivity when your application
* first launches, and the xmpp stream is unable to connect to the host.
* In cases such as this it may be desireable to start monitoring the network for reachability changes.
* This way when internet connectivity is restored, one can immediately connect the xmpp stream.
* This is possible via the manualStart method,
* which will trigger the class into action just as if an accidental disconnect occurred.

I don't know if this XMPPReconect class meets your demand.
