Program doesn't jump in Delegate-Method

Good Morning Community,

I have a problem, because I have implemented an CoverFlowViewController.m with an Delegate method, but the Debugger NEVER jump in this method, does anyone know why? Here is the code:

- (void)viewDidLoad {
    [super viewDidLoad];
    UIButton *weiter = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    weiter.frame = CGRectMake(100, 400, 120, 40);
    [weiter addTarget:self action:@selector(goToChart) forControlEvents:UIControlEventTouchUpInside];
    NSString *ansicht = @"Weiter";
    [weiter setTitle:ansicht forState:UIControlStateNormal];
    [self.view addSubview:weiter];
    // loading images into the queue
    loadImagesOperationQueue = [[NSOperationQueue alloc] init];
    NSString *imageName;
    for (int i=0; i < 10; i++) {
        imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];
        imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
        UIImage *aktuellesImage = imageView.image;
        UIImage *scaledImage = [aktuellesImage scaleToSize:CGSizeMake(100.0f, 100.0f)];
        [(AFOpenFlowView *)self.view setImage:scaledImage forIndex:i];
    }
    [(AFOpenFlowView *)self.view setNumberOfImages:10];

}

- (void)openFlowView:(AFOpenFlowView *)openFlowView selectionDidChange:(int)index{
    NSLog(@"%d is selected",index);
}

Does anyone know why the Debugger (= the Programm) never jump into the selectio开发者_开发技巧nDidChange() method?

I have no solution since three days, and hope somebody could help me?

Greetings and Thank you beforehand Marco

are you sure you connected the viewDelegate to your viewController?
Please add NSLog(@"Delegate: %@", ((AFOpenFlowView*)self.view).viewDelegate); at the end of your viewDidLoad method to see if it is connected.

Add

((AFOpenFlowView *)self.view).viewDelegate = self; on the init or viewDidLoad method
