Question

I have two scenes. A regular, full-screen iPad view and another popover view. Tapping a button loads the popover view with no problems. In the popover view I have a button that will perform some action and is also linked to a storyboard modal transition.

The idea is that pressing the button from the popover view will save the user’s selection state and send that data to the main view. I have no issues with the data saving, that works just fine.

The issue I am having is that when I press the button from the popover view, the main view’s viewDidLoad method actually completes before the popover view’s IBAction method does. So the main view gets the data, but since the view already loaded it is not able to update the label in time.

I tried creating multiple popover view scenes and added multiple buttons to the main view that will link to these new scenes. The weird part is that some of them work just fine. Some of them will perform the IBAction method and then it transitions back to the main view via a modal transition. There seems to be no rhyme or reason why one loads before the other.

I suppose a possible solution would be to perform the transition manually within the IBAction method of the popover view. I am definitely new to this so there may be something fundamental about transitions that I am missing.

In the view controller of view on which the button is present… When segue is going to be performed. You can pass data in

 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
    {
        // Get reference to the destination view controller
        YourViewController *vc = [segue destinationViewController];

        // Pass any objects to the view controller here, like...
        [vc setMyObjectHere:object];
    }
}

This method is called before the view is loaded..
