Question : Memory Leak in Poping Modal View Controller

In controller named controller1, I am pushing a modal view controller

1:
2:
3:
4:
5:
6:
7:
8:
	 AddConversationViewController *addController = [[AddConversationViewController alloc] 
	 initWithNibName:@"AddConversationViewController" bundle:nil];
	 //addController.delegate = self;	 
	 UINavigationController *navigationController = [[UINavigationController alloc]
	 initWithRootViewController:addController];
	 [self presentModalViewController:navigationController animated:YES];
	 [addController release];
	 [navigationController release];

and then in that addcontroller, I have allocated several object. but in the dealloc method, when i release those objects, I will get BAD_ACCESS warning when i dismiss the modal view controller. If I don't release those objects I have allocated, it doesn't give the BAD_ACCESS warning.
those objects I have allocated before are not released nor retained.

Does anybody know how to fix this memory leak?

Answer : Memory Leak in Poping Modal View Controller

The BAD_ACCESS error means that you are releasing an object that another function is currently using. Run your code like this:

       AddConversationViewController addController = [[AddConversationViewController alloc]
       initWithNibName:@"AddConversationViewController" bundle:nil];
       //addController.delegate = self;
       UINavigationController navigationController = [[UINavigationController alloc]
       initWithRootViewController:addController];
       [self presentModalViewController:navigationController animated:YES];
       [addController release];
NSLog(@"After addController released");
       [navigationController release];
NSLog(@"After navigationController released");

This adds some console messages before you release each of your objects. If you see After addController released in your console, you know that [addController release]; is not causing your crash. If you see both of those console messages, you know that none of those statements are causing a crash, but most likely, one of those 2 release statements is causing the crash. I am thinking that the [navigationController release]; statement is causing your crash because you need that to move views via your navigationController. If you remove that line, you shouldn't crash. Removing addController shouldn't cause a crash because you just made that to move the view and it doesn't do anything else. If you have any further questions, please feel free to ask me about them.
