Question

Hi I have a weird problem,

In my MainViewController class I post a notification when ever a button gets pressed

[[NSNotificationCenter defaultCenter] postNotificationName:@"step" object:nil];

in the class it self i have a observer

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(step) name:@"step" object:nil];

which runs the “step” method

- (void)step {
    NSLog(@"works");
}

and in another class called Slide1ViewController I have a observer as well

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        NSLog(@"works 2");

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(step) name:@"step" object:nil];
    }
    return self;
}

and the dealloc method removes it

- (void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"step" object:nil];
}

In the MainViewController the method gets called, but never in the Slide1ViewController.

The Slide1ViewController gets initialized like that:

Slide1ViewController*test = [[Slide1ViewController alloc] initWithNibName:@"Slide1ViewController" bundle:nil];
test.view.frame = CGRectMake(1024*0, 0, 1024, 768);
[contentScrollView addSubview:test.view];
