创建socket连接。包括服务端和客户端 一个例子。
创建协议:
// do_common.h
#import <Foundation/Foundation.h>
#include <sys/socket.h>
#define DO_DEMO_PORT 12345
#define DO_DEMO_HOST "localhost"
@protocol ClientProtocol
- (void)setA:(float)arg;
- (void)setB:(float)arg;
- (float)getSum;
- (void)helloFromClient:(id)client;
@end
@protocol ServerProtocol
- (bycopy NSString *)whoAreYou;
@end
//创建服务端
//DOServer.h
#import <Cocoa/Cocoa.h>
#import "do_common.h"
@interface DOServer : NSObject <ClientProtocol>
{
float a;
float b;
}
@end
// do_server.m
#import "DOServer.h"
// server
@implementation DOServer
- (id)init
{
[super init];
a = 0;
b = 0;
return self;
}
- (void)dealloc
{
[super dealloc];
}
- (void)helloFromClient:(in byref id<ServerProtocol>)client
{
NSLog([client whoAreYou]);
}
- (oneway void)setA:(in bycopy float)arg
{
a = arg;
}
- (oneway void)setB:(in bycopy float)arg
{
b = arg;
}
- (float)getSum
{
return (float)(a + b);
}
@end
创建好后就可以把服务端开启了。
#import <Foundation/Foundation.h>
#import "DOServer.h"
int main (int argc, const char * argv[])
{
NSSocketPort *port;
NSConnection *connection;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSRunLoop *runloop = [NSRunLoop currentRunLoop];
DOServer *server = [[DOServer alloc] init];
///
NS_DURING
port = [[NSSocketPort alloc] initWithTCPPort:DO_DEMO_PORT];
NS_HANDLER
NSLog(@"failed to initialize TCP port.");
exit(1);
NS_ENDHANDLER
connection = [NSConnection connectionWithReceivePort:port sendPort:nil];
[port release];
// vend the object
[connection setRootObject:server];
[server release];
[runloop run];
[connection release];
[pool release];
exit(0);
return 0;
}
