问题
I am trying to create a simple Today Extension. I was able to add a label wherein the value can be updated via the main app. Now, I am exploring the possibility to update the value in main app via the extension. However, when I tried to add a textfield, I cannot input anything.
Is this a limitation of the extension? If not, can you please guide me how to accomplish this? Thank you very much!

Unfortunately, it is a limitation.
It says in Apple's extension programming guide:
Because user interaction with Today widgets is quick and limited, you should design a simple, streamlined UI that highlights the information users are interested in. In general, it’s a good idea to limit the number of interactive items in a widget. In particular, note that iOS widgets don’t support keyboard entry.
