Hello! I've two view controller. In the first, i write my room's name (for example bedroom) and push the button. In second view, i see the name of my room, and insert other details, like number of bulbs, name of bulbs and when i've finished, I press on a button that keeps me coming back to first controller. I'm using uinavigation bar for this two steps, but i have a question. If I press on bedroom's button, i don't see the details that i've wrote before. How i can see that?
