Hi All,
I have two application in cocoa . My aim is to communicate with a
protocol between both the application using IPC mechanism (through
NSConnection) but I am unable to achieve my goal.
I want to use id < MyProtocol > protocol as inout parameter for two way
communication.
Please see my code below and guide me what I am missing.
//***********************************Vendor
Process**********************************
// Root.h
@protocol MyProtocol
- (long) getNumber ;
@end
@protocol RootProtocol
- (HRESULT) getData : (id < MyProtocol >) pMyProtocol;
@end
@interface CRoot : NSObject < RootProtocol>
{}
@end
@protocol RemoteObjProtocol
- (id) GetDistObject;
@end
@interface CRootService : NSObject < RemoteObjProtocol >
{}
@end
@interface OutClass : NSObject < MyProtocol >
{}
@end
// Root.m
@implementation OutClass
- (id) init {return self;}
- (void) dealloc {[super dealloc];}
- (long) getNumber {return 10;}
@end
@implementation CRoot
- (id) init{return self;}
- (void) dealloc{[super dealloc];}
- (HRESULT) getData : (id < MyProtocol >) pMyProtocol
{
pMyProtocol = [[[CRootService alloc] init] autorelease];
return S_OK;
}
@end
@implementation CRootService
- (id) init
{
[[NSConnection defaultConnection] setRootObject: self];
[[NSConnection defaultConnection] registerName: @"RootService"];
return self;
}
- (void) dealloc{[super dealloc];}
- (id) GetDistObject
{
return [[[CRoot alloc] init] autorelease];
}
@end
//************************Reciever Process**************************
/// Test.h
@interface CTest : NSObject {}
+ (id) ReturnDistObj : (NSString*)registeredName;
@end
// Test.m
id remoteProxy;
@implementation CTest
- (id) init{return self;}
- (void) dealloc{[super dealloc];}
+ (id) ReturnDistObj : (NSString*)registeredName
{
remoteProxy = [[NSConnection rootProxyForConnectionWithRegisteredName:
registeredName host: nil] retain];
[remoteProxy setProtocolForProxy:@protocol(RemoteObjProtocol)];
if (remoteProxy && [remoteProxy conformsToProtocol: @protocol(
RemoteObjProtocol)])
{
return [remoteProxy GetDistObject] ;
}
else
return NULL;
}
@end
int main()
{
id < RootProtocol > pRootProtocol = [CTest ReturnDistObj:
@"Rootservice"];
id < MyProtocol > pMyProtocol = nil;
[pRootProtocol getData: pMyProtocol ];
return 1;
}
