Well for one thing, you're "return"ing before you call "[theError
displayError:@"Server non connesso"];" ... so that will never get
called. You might want to review Apple's Introduction to Objective-C:

index.html

Hi and Thank you,
the problem is the secondary thread...
-(void)startConnection:(id)owner
{
NSAutoreleasePool * myPool=[[NSAutoreleasePool alloc]init];
[conditionLock lockWhenCondition:CONNECTION];
NSLog (@"start connection");
if (![sckt isConnected])
{
sckt = nil;
int portw = 4321;
NSString * host = [NSString stringWithString:IPUS];
sckt = [Socket socket];
[sckt retain];
[sckt setBlocking:YES];
[sckt connectToHostName:host port:portw];
if ([sckt isConnected])
{
[conditionLock unlockWithCondition:CHECK_SOCKET];
[aTextView insertText:@"Connected\n"];
/*time = [NSTimer scheduledTimerWithTimeInterval:0.05 target:self
selector: @selector(onTimer:)
userInfo: nil
repeats: YES];*/
}
else
{
return ;
[theError displayError:@"Server non connesso"];
}
}
[myPool release];
[NSThread exit];
}
If the connection failed ... I have to stop the thread before
getting this error:
[Session started at 2005-11-30 15:37:39 +0100.]
2005-11-30 15:37:41.897 test[710] start connection
2005-11-30 15:37:41.909 test[710] An uncaught exception was raised
2005-11-30 15:37:41.909 test[710] Socket: Not connected
2005-11-30 15:37:41.909 test[710] *** Uncaught exception: <Socket:

Thanks again

You can technically return; in a void function.
But I would re-examine your flow if you have to do that.

Hi to all,
I need a simple way to interrupt a function returning void.
-(void)method:(NSString*)aString
{
if (condition)
{
}
else
{
something like exit....
}
}
Anyone can tell me how to do?
Thank you all
Andrea
