For iOS, is it possible to have a Toast message that can display on top of system app Settings?

Question

I have a button in my app that brings up the system app settings UI. Instructions are given around the button.

I want to provide further instructions to the user via a toast message after the settings page shows up so they know exactly what to do. It's not a super intuitive setting, related to notification style, and such instructions would be a lot clearer when the user is actually on the settings page.

In Android, this is easily done via toast.makeText().show(). The resulting toast would have no problem going on top of the system settings UI.

In iOS though, I've looked up several guides, mostly using the UIView animation. The problem is, the resulting toast window seems to only work inside the app itself. It cannot go on top of the system settings UI.

Is what I want to achieve technically possible in iOS?

Solution

No. You are sandboxed; Settings is a different app and you cannot impose anything on to its interface.

I highly doubt it.

I think it's not possible. Rather you can show an UIAlertController or custom popup view and show the instruction there. Then when user tap the yes/ok button of the alertController, take them to system setting app.

@talha_kuet Yeah that's what I already did. Unfortunately this particular setting requires 2 more level of clicks inside the settings, and it'd be a lot clearer if the instructions are actually shown on the settings page itself.

That's unfortunate. We obviously don't want to interfere with other apps. I wish they'd expose a system level display like Android's toast . Thanks for the confirmation!

Yeah, our app has the same issue. We send you off to system settings where you have to do something really confusing.
