在NSConnections上调用rootProxy不返回

Question

我有两个Cocoa-GUI-应用程序(用ARC编译，没有沙箱)。

应用程序一具有以下功能：

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // Insert code here to initialize your application

    CommController *cc = [CommController new];
    NSConnection *theConnection;
    theConnection = [NSConnection new];
    [theConnection setRootObject:cc];
    if ([theConnection registerName:@"MyServer"] == NO) {
        /* Handle error. */
        NSLog(@"Could not start server.");
    }

}

应用程序二具有以下功能：

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    id theProxy;
    NSConnection *theConnection;

    theConnection = [NSConnection
                     connectionWithRegisteredName:@"MyServer"
                     host:nil];
    theProxy = [theConnection rootProxy];
    [theProxy setProtocolForProxy:@protocol(NetProto)];

}

来自第二个应用程序的调用[theConnection rootProxy]永远不会返回。如果我使用废弃的[NSConnection defaultConnection]而不是[NSConnection new]，它可以工作。因此，我正在寻找一种非弃用的方法来获取rootProxy。

Answer 1

按照Ken Thomases的建议，保持对NSConnection对象的强引用是有帮助的。

Answer 2

CommController *cc = [CommController new];
    NSConnection *theConnection;
    theConnection = [NSConnection new];
    [theConnection setRootObject:cc];
    if ([theConnection registerName:@"MyServer"] == NO) {
        /* Handle error. */
        NSLog(@"Could not start server.");
    }
[[NSRunLoop currentRunLoop] run];//Start the current runloop
