Memory management question

[tiltem]

I have navigation based template, using core data(not sure if that matters), and a UIViewController as a second view. I get to the second view by clicking the add (+) button in the top right of the navigation bar. In here I have the top right button of the navigation controller call my save method when clicked. In this save method I create a RootViewController object and call one of the rootView's methods and then pop back to the root view.

The issue is that if I release this root view object the app crashes, if I do not release the object it seems to work fine. I just need to know if this is causing a memory leak?

Here is the code for the save method, this is in my UIViewController, the RootViewController is a UITableViewController:

-(void) save{
	if ([newEventName.text length]== 0) {
		UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Missing Event Name" message:@"Please enter an event name or Cancel." delegate:self cancelButtonTitle:@"DONE" otherButtonTitles:nil];
		[alert show];
		[alert release];
		return;
	}
	eventDate = dateStartedPicked.date;
	RootViewController *rvc =[[RootViewController alloc] initWithNibName:nil bundle:nil];
	[rvc addEventName:newEventName.text eventDate:eventDate];
	[self.navigationController popToRootViewControllerAnimated:YES];
//	[rvc release];   <--- Dies here if released
}

I feel like the rvc object is now considered self since I have popped back to its view, and thus may not need to be released. I don't know but would like to know for sure.

Thanks!!!

Are you expecting rvc to be pointing to a pre-existing controller in your app? As far as I can see you're creating a brand new instance of the RootViewController class, calling the addEventName: method on it, and then immediately destroying it with [rvc release].

Is that what you want, or were you trying to get a pointer to an existing instance of RootViewController? You'd have to go through the AppDelegate or create your own singleton class for that.

Yes, I wanted to get access to the existing (original) RootViewController, but was unsure about how to do that from inside the new UIViewController. How would I go about creating a singleton class, and how can it be accessed through the app delegate?

I appreciate the help!!
