Question

Do UINavigationController buttons added need to be autoreleased? is this code ok?

Background – I’m seeing a range of navigation issues occuring in my application after I start triggering “memory warnings”. I’m wondering if it is something to do with the question I posed here. Questions would include:

1. Is code below correct?
2. Any additional memory management code required elsewhere? (e.g. dealloc method? – I’ve currently got no code here to deallocate any buttons)
3. Any other tips re what might be going wrong with navigation bar populations/screen flow issues using a UINavigationController after simulating memory warnings

Code Below:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationItem.rightBarButtonItem = [ 
    [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAction:)] autorelease];   // IS AUTORELEASE HERE CORRECT?
    self.navigationItem.leftBarButtonItem = self.editButtonItem;  
    self.title = @"Views";   

thanks

I always just use autorelease and I think that it should do just fine.
