Question

Here’s how I set up my app. I have a root view that loads a subview over the top of it during the viewDidLoad method. In the subview I have a button that, when clicked, hides itself and reveals the root view. Everything is working great, but I hate having a view that is loaded but is not in use. I tried to put a method in the delegate that does this:

[theLaunch release];

…where theLaunch is my Subview.

This method, located in my delegate, is called hidetheLaunch.

Then I was trying to call this method from within the subview:

[[UIApplication sharedApplication].delegate hidetheLaunch];

But it says -hidetheLaunch not found in protocol.

Am I doing this all wrong?

Thanks in advance!

You need to first cast the UIApplicationDelegate to your specific delegate’s type:

[((MyAppDelegate *) [UIApplication sharedApplication].delegate) hidetheLaunch];
