Container View Controllers - notify parent of action

Question

Say I have a custom container view controller (MainViewController) where I do something like this:

- (void)viewDidLoad
{
    [super viewDidLoad];        

           


        

Answer 1

There's another way too... Every view controller has a parentViewController property so using that you can do this...

In MainViewController define a method for the action you want to perform...

- (void)someMethod:(BOOL)someParam;

Then in HomeViewController you can do...

MainViewController* parent = (MainViewController*)[self parentViewController];
[parent someMethod:paramValue];

HTH :)
