Sending an NSImage on a Network
Post: #1
Hopefully there are some Cocoa game network programmers, because my question is about sending an NSImage from one computer to another.
Additionally, could someone help me out with the protocols. I don't know how to write them for this kind of thing.
Here's all of my server and client code:

Code:
---------- CLIENT CODE ----------
/* MyView */
#import <Cocoa/Cocoa.h>
@interface MyView : NSView
{
NSImage *myImage;
}
- (void)setImage:(NSImage *)image;
@end
#import "MyView.h"
@implementation MyView
- (id)initWithFrame:(NSRect)frameRect
{
if ((self = [super initWithFrame:frameRect]) != nil)
{
}
return self;
}
- (void)setImage:(NSImage *)image
{
[image retain];
[myImage release];
myImage = image;
[self setNeedsDisplay:YES];
}
- (void)drawRect:(NSRect)rect
{
NSRect bounds = [self bounds];
if(myImage)
{
NSRect imageRect;
NSRect drawingRect;
imageRect.origin = NSZeroPoint;
imageRect.size = [myImage size];
drawingRect = imageRect;
[myImage
drawInRect:drawingRect
fromRect:imageRect
operation:NSCompositeSourceOver
fraction:1.0
];
}
else
NSLog(@"Did not draw myImage.");
}
@end
/* Controller */
#import <Cocoa/Cocoa.h>
#import "MyView.h"
@interface Controller : NSObject
{
NSSocketPort *port;
NSConnection *connection;
IBOutlet NSView *myView;
}
- (void)setImage:(NSImage *)image;
- (IBAction)vendService:(id)sender;
@end
#import "Controller.h"
@implementation Controller
- (void)setImage:(NSImage *)image
{
[myView setImage:image];
}
- (IBAction)vendService:(id)sender
{
port = [[NSSocketPort alloc] initWithTCPPort:12345];
connection = [[NSConnection connectionWithReceivePort:port sendPort:nil] retain];
[connection setRootObject:self];
if(![[NSSocketPortNameServer sharedInstance] registerPort:port name:@"server"])
{
NSLog(@"Could not register name of server.");
}
}
@end
---------- CLIENT CODE ----------
/* Controller */
#import <Cocoa/Cocoa.h>
@interface Controller : NSObject
{
IBOutlet NSTextField *messageField;
NSSocketPort *port;
NSConnection *connection;
NSDistantObject *proxy;
NSImage *anImage;
}
- (IBAction)createProxy:(id)sender;
- (IBAction)sendImage:(id)sender;
@end
#import "Controller.h"
@implementation Controller
- (id)init
{
self = [super init];
if ( self )
{
anImage = [[NSImage alloc] initWithContentsOfFile:@"/users/jordanevans/desktop/snapshot.tiff"];
[anImage retain];
}
return self;
}
- (IBAction)createProxy:(id)sender
{
port = [[NSSocketPortNameServer sharedInstance] portForName:@"server" host:@"*"];
connection = [NSConnection connectionWithReceivePort:nil sendPort:port];
proxy = [[connection rootProxy] retain];
}
- (IBAction)sendImage:(id)sender
{
if( ![proxy setImage:anImage] )
{
NSLog(@"Did not set send image.");
}
}
@end

My general approach would be to use archivers and unarchivers. This makes sending objects over a network pretty trivial.
