Contextual or global: action label in Navigation Bar and Segmented Control

Question

I'm trying to layout a screen where users could delete some content using the classic iOS pattern:

1. tap on the Nav-Bar's "edit" label (top-right)
2. then tick the items to delete
3. validate

Nothing complicated here, right?

But what if I need to add a segmented control?

Is the edit label supposed to be "global" to this screen, whichever segmented control we're on?

Or could this edit label be contextual and disappear or change if we press on "section2"/"section3".

In my case, I just need the deletion feature on "section1". I might either not need a top-left label on the other remaining sections or need a different one.
I'm asking because, due to its location, the "edit" label appears to be related to the page and not the the active segment below.
Would it go against iOS guidelines to make this label contextual and therefore change according to the active segmented control?
Have you ever encountered such case?

Best regards,

Answer 1

I think it would be totally fine with the Edit button contextually relevant to the content or segment. You can try to disable or hide the Edit button when users switch to other segments.

But it's true that the location of the button makes it a bit like for the whole page. The alternative approach would be that having the Edit button in the header of the table view, instead of in the navigation header.

Another thing to consider is that to use the cell-swipe gesture (swiping on a row all the way to the left or right to trigger actions).

Answer 2

The existing approach you have taken is perfectly fine and doesn't go against iOS guidelines. Try and see if you can place the edit action in footer of the page.

Even iOS follows the same convention - check their Clock app and see the Alarm & World Clock tabs.

Edit:

If you see, the Edit option is same for the World Clock and Alarm Tab
