我正在尝试使用NSSocketPort
在同一台计算机上的两个应用程序之间创建连接,但它似乎只是单向工作。
我有一台服务器,可以创建NSMutableDictionary
并将其设置为rootObject
。客户端读取rootProxy
并在服务器创建字典时获取字典。但后来我希望客户端在字典中添加一个额外的键/值集,并再次将字典设置为rootObject
。但是,在客户端设置它之后,服务器似乎没有收到最后一个值/密钥集。
服务器
self.portRecv = [[NSSocketPort alloc] initWithTCPPort:30028];
self.conn = [NSConnection connectionWithReceivePort:self.portRecv sendPort:nil];
self.data = [NSMutableDictionary dictionary];
[self.data setObject:@"Value" forKey:@"serverSet"];
self.conn.rootObject = self.data;
self.conn.delegate = self;
这是服务器读取值的方式:
self.data = (NSMutableDictionary*)[self.conn rootProxy];
客户端:
self.portSend = [[NSSocketPort alloc] initRemoteWithTCPPort:30028 host:@"127.0.0.1"];
self.conn = [NSConnection connectionWithReceivePort:nil sendPort:self.portSend];
self.conn.delegate = self;
self.data = (NSMutableDictionary*)[self.conn rootProxy];
[self.data setObject:@"Value" forKey:@"clientSet"];
self.conn.rootObject = self.data;
客户端self.data
收到"serverSet : Value"
就好了,但是当我让服务器在客户端设置[self.conn rootProxy]
服务器后读取"clientSet : Value"
时获取一个包含serverSet
值的字典,而不是clientSet
。
我正在回答下面的代理信息:
- (BOOL)makeNewConnection:(NSConnection *)conn sender:(NSConnection *)ancestor
{
return YES;
}
- (BOOL)connection:(NSConnection *)ancestor shouldMakeNewConnection:(NSConnection *)conn
{
return YES;
}
- (BOOL)connection:(NSConnection *)conn handleRequest:(NSDistantObjectRequest *)doReq
{
NSInvocation *invocation = [doReq invocation];
[invocation invoke];
if ([invocation selector] == @selector(entitiesByName))
{
id retVal;
[invocation getReturnValue:&retVal];
NSDictionary *rebuilt = [NSDictionary dictionaryWithDictionary:retVal];
[invocation setReturnValue:&rebuilt];
}
[doReq replyWithException:nil];
return YES;
}
我不能添加值并将rootObject
返回给服务器吗?我怎么能这样做?
答案 0 :(得分:0)
我设法通过实现一个实现NSCoding
协议的类来解决这个问题,然后将其用作rootObject
。通过这样做,我能够从客户端调用服务器对象上的不同方法。
它最终是这样的:
服务器强>
int port = 30012;
self.socketModel = [[SocketModel alloc] init];
self.socketModel.statusBarUiDelegate = self;
NSSocketPort* recvPort = [[NSSocketPort alloc] initWithTCPPort:port];
self.conn = [NSConnection connectionWithReceivePort:recvPort sendPort:nil];
[self.conn setRootObject:self.socketModel];
<强> SocketModel:强>
@interface SocketModel : NSObject<NSCoding>
-(NSString*)performTask:(NSString*)data;
-(void)taskCompleted;
@end
<强>客户端:强>
NSString* data = @"pewpew";
NSSocketPort* recv = [[NSSocketPort alloc] initRemoteWithTCPPort:30012 host:@"127.0.0.1"];
self.conn = [NSConnection connectionWithReceivePort:nil sendPort:recv];
[self.conn setRequestTimeout:5];
NSString* result = nil;
SocketModel* obj = nil;
obj = (SocketModel*)[self.conn rootProxy];
result = [builderObj performTask:data];
[obj taskCompleted];
我甚至可以在SocketModel
上创建委托并将其分配给我的客户端,这使服务器向客户端提供进度信息。
