Objective-C - Detect dismiss of a view after page curl

I have a Main View which call a settings panel in another view with the page curl transition. All seems fine, but when I close the settings view it doesn't trigger the "viewWillAppear" method of my Main View causing me a lot of troubles because it doesn't get updated with the settings.

There is an answer which seems fine for me, but I don't know how to implement it. There is another easy way or someone who can explain to me how to apply that answer?

Thanks in advance.

Instead of reacting to views, you should probably react to settings changes. What I mean by that is that it would be a more solid design to use Key-Value Observing (KVO) so that your main view can be notified of changes to the objects that represent your settings.

Alternatively, if you can't or don't want to observe a specific object, you can use NSNotificationCenter and have your settings view fire a notification when the new settings are applied and your other view can register to listen to those notifications. Here is a simple example of that.

I hope this helps solve your problem.
