Method should be called when a view gets into focus

Question

in my iOS project I use InAppSettings. This is missing a delegate in the modal view controller for willDismiss.

So when the modal view gets dismissed I want a method to be called in my main view controller. How can I do this? Is there a method in a view controller that gets triggered whe the view is in focus again?

Answer 1

You could try something like this

BOOL settingsLaunched = NO;

-(void)presentInAppSettingsViewController
{
    //Show the settings modal view controller here

    //Set our flag
    settingsLaunched = YES;
}

-(void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    if(settingsLaunched)
    {
        //Your code here
    }
}
