使用分布式对象实现进程间的通信

Question

我不能设法出售代理对象，它只是停留在客户端时，试图获得连接

NSConnection *conn = [NSConnection connectionWithRegisteredName:@"server"  host:nil];

下面是我如何注册连接和自动售货对象

//server
-(void)initServer {

NSConnection * connection = [[NSConnection alloc]init];

MZRemoteObject * obj = [[MZRemoteObject alloc]init];
obj.message = @"hello world";
[connection setRootObject:obj];
if([connection registerName:@"server"]== NO){
    NSLog(@"error Register Server");
}
NSLog(@"Registered Server");
}

客户端(获取自动售货对象)

- (void)recieveMessage {

NSDistantObject *proxy;
NSConnection *conn = [NSConnection connectionWithRegisteredName:@"server"  host:nil];

if (!conn) {
    NSLog(@"conn recieve message error");
}

proxy = [conn rootProxy];
MZRemoteObject * obj =(MZRemoteObject*)proxy;

if (!proxy) {
    NSLog(@"proxy,recieve message error");
}
NSLog(@"----%@",obj.message);
}

谁能告诉我我做错了什么？

[[NSRunLoop currentRunLoop] run];  

在-(空)initServer方法中启动当前的运行循环。

-(void)initServer {

NSConnection * connection = [[NSConnection alloc]init];

MZRemoteObject * obj = [[MZRemoteObject alloc]init];
obj.message = @"hello world";
[connection setRootObject:obj];
if([connection registerName:@"server"]== NO){
    NSLog(@"error Register Server");
}
NSLog(@"Registered Server");
[[NSRunLoop currentRunLoop] run];  
}
