如何从通知名称中创建信号？例如,我想从:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(userDidChange:)
                                             name:kTTCurrentUserLoggedOffNotification
                                           object:nil];

类似于:

[signalForName(kTTCurrentUserLoggedOffNotification) subscribeNext:^(id x){
...
}];
