Hi @soso. Warm welcome to the MySensors community!
MySensors is a fantastic project, but it might not be the right project for you. MySensors takes care of communication between sensors, and from sensors to a gateway which in turn connects to a Home Automation Controller. To me, it sounds you don't need any of that. The RFduino can use bluetooth to communicate directly with an iOS device. No need to communicate between sensors, no need for a gateway and no need for a Home Automation Controller.
You might be better off asking in the rfduino forum.
With that said, there might be some rfduino users who also use MySensors so hopefully someone is able to give some recommendations. If you want to read more about what can be done with MySensors, take a look at the getting started guide.
