Objective c NSSocketPort端口仅单向工作

我试图用一个

NSSocketPort

在同一台计算机上的两个应用程序之间创建连接，但它似乎只有一种工作方式。 我有一个服务器，它创建一个

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。但是，我希望客户端向字典添加一个额外的键/值集，并再次将字典设置为

rootObject

。但是，服务器似乎没有收到客户端设置后的最后一个值/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;

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;

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];

@interface SocketModel : NSObject<NSCoding>
-(NSString*)performTask:(NSString*)data;
-(void)taskCompleted;
@end

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];

这是服务器读取值的方式：

self.data = (NSMutableDictionary*)[self.conn rootProxy];

客户端：

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;

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;

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];

@interface SocketModel : NSObject<NSCoding>
-(NSString*)performTask:(NSString*)data;
-(void)taskCompleted;
@end

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];

客户端的

self.data

接收到

“serverSet:Value”

很好，但是当客户端设置

“clientSet:Value”

后，我让服务器读取

[self.conn rootProxy]

时，服务器会得到一个带有

serverSet

值的字典，而不是

clientSet

我将按照以下方式回答学员的信息：

- (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;
}

难道我不能添加一个值并将

rootObject

返回到服务器吗？我如何做到这一点？

我通过实现一个类来解决这个问题，该类实现了

NSCoding

协议，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

结果是这样的：

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;

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;

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];

@interface SocketModel : NSObject<NSCoding>
-(NSString*)performTask:(NSString*)data;
-(void)taskCompleted;
@end

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];

袜子型号：

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;

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;

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];

@interface SocketModel : NSObject<NSCoding>
-(NSString*)performTask:(NSString*)data;
-(void)taskCompleted;
@end

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];

我甚至能够在我的

SocketModel

上创建一个委托，并将其分配给我的客户机，这使得服务器向客户机提供进度信息。

好吧，我也有同样的委托problem@DenisKohl事实上，我找到了解决问题的有效方法。我将其创建为一个答案：-）
