RacSignal disposed automatically

Question

I have merged some racsignals into a single Racsignal. And subscribed the merged signal. Now if any of the signals that i have merged sends error event all the merged signals are disposed. I want all the signals to continue there executing if any signal has failed.

Answer 1

I can suggest two options:

1. Apply catchTo:[RACSignal empty] to each signal to squelch any signal that errors.
2. Apply -materialize to each signal which changes all subscriber events into concrete instances of RACEvent.

Using option #1 drops the error objects and prevents the other merged signals from being disposed, but leaves the subscriber uninformed about all errors.

Using option #2 means your subscriber has to unwrap the RACEvent and then conditionally perform the value or error handling logic, inside the next block.
