mhhh I tried, but no good results...
the problem is:
my app take a shot of the screen and send it via socket, so the same app on other machine receive it via rendezvous...
I'm successful to run, but the problem is that any refresh the app must be:
- resolve the address
- connect with socket and NSNotification
- catch the image...
not good ....
any other suggest for me?

Hi,
You just need to setup a timer that will refresh your view every few seconds. This is done with the NSTimer class. Basically, you need to set up a timer with a certain interval as your refresh rate, give it a selector (function pointer) and then schedule the timer with your run loop. Or, for convenience, the scheduledTimerWithTimeInterval:target:selector:userInfo:repeats: method will handle all of that for you. Here's an example:
<x-tad-bigger>- (</x-tad-bigger><x-tad-bigger>void</x-tad-bigger><x-tad-bigger>)awakeFromNib
{
</x-tad-bigger><x-tad-bigger>// Setup a three-second timer than calls 'refresh:'.</x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>// The 'timer' should be an NSTimer instance variable.</x-tad-bigger><x-tad-bigger>
timer = [[NSTimer scheduledTimerWithTimeInterval:</x-tad-bigger><x-tad-bigger>3.0</x-tad-bigger><x-tad-bigger>
target:</x-tad-bigger><x-tad-bigger>self</x-tad-bigger><x-tad-bigger> selector:</x-tad-bigger><x-tad-bigger>@selector</x-tad-bigger><x-tad-bigger>(refresh:)
userInfo:</x-tad-bigger><x-tad-bigger>nil</x-tad-bigger><x-tad-bigger> repeats:</x-tad-bigger><x-tad-bigger>YES</x-tad-bigger><x-tad-bigger>] retain];
}
- (</x-tad-bigger><x-tad-bigger>void</x-tad-bigger><x-tad-bigger>)dealloc
{
[timer invalidate]; </x-tad-bigger><x-tad-bigger>// Stop the Timer</x-tad-bigger><x-tad-bigger>
[timer release]; </x-tad-bigger><x-tad-bigger>// Release the Timer</x-tad-bigger><x-tad-bigger>
[</x-tad-bigger><x-tad-bigger>super</x-tad-bigger><x-tad-bigger> dealloc];
}
- (</x-tad-bigger><x-tad-bigger>id</x-tad-bigger><x-tad-bigger>)sender
{
</x-tad-bigger><x-tad-bigger>// Reload Image Here</x-tad-bigger><x-tad-bigger>
}
</x-tad-bigger>
