Sorry for another message of the same argument...
My app is more similar to PictureSharing & PictureSharingBrowser that you can find on:
http://developer.apple.com/samplecode/PictureSharing/PictureSharing.html
http://developer.apple.com/samplecode/PictureSharingBrowser/PictureSharingBrowser.html
the difference is that my app don't share an images but the desktop of another user found on rendezvous...simply share a snapshot.
Now I want to render this snapshot dinamic... like a RemoteDesktop, a sort of refresh of the snapshot.
I implemented a NSTimer that call a refresh metod like this:
- (void)awakeFromNib
{
// Setup a three-second timer than calls 'refresh:'.
// The 'timer' should be an NSTimer instance variable.
timer = [[NSTimer scheduledTimerWithTimeInterval:3.0
target:self selector:@selector(refresh:)
userInfo:nil repeats:YES] retain];
}
- (void)dealloc
{
[timer invalidate]; // Stop the Timer
[timer release]; // Release the Timer
[super dealloc];
}
- (id)sender
{
socketToRemoteServer = socket(AF_INET, SOCK_STREAM, 0);
if(socketToRemoteServer > 0) {
NSFileHandle * remoteConnection = [[NSFileHandle alloc] initWithFileDescriptor:socketToRemoteServer closeOnDealloc:YES];
if(remoteConnection) {
NSLog( @"notifica" );
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(readAllTheData:) name:NSFileHandleReadToEndOfFileCompletionNotification object:remoteConnection];
if(connect(socketToRemoteServer, (struct sockaddr *)socketAddress, sizeof(*socketAddress)) == 0) {
[remoteConnection readToEndOfFileInBackgroundAndNotify];
}
} else {
close(socketToRemoteServer);
}
}
}
as you seen the problem is that refresh: always reconnect with socket etc. etc. (so my app take also the 70% of CPU) but this is the only way that I have found to obtain a new shot and view on my NSImageView.
I don't know how to resolve this... if anyone want I can send the code.
Thanks!
