Hi, I've created a custom class AnimalView which is a subclass of UIView containing a UILabel and a UIImageView.

@interface AnimalView : UIView {
    UILabel *nameLabel;
    UIImageView *picture;
}

Then I added in several AnimalView onto the ViewController.view. In the touchesBegan:withEvent: method, I wanted to detect if the touched object is an AnimalView or not. Here is the code for the viewController:

@implementation AppViewController

- (void)viewDidLoad {
    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:...
    [self.view addSubview scrollview];

    for (int i = 0; i<10; i++) {
        AnimalView *newAnimal = [[AnimalView alloc] init];
        // customization of newAnimal
        [scrollview addSubview:newAnimal;
    }
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    UIView *hitView = touch.view;
    if ([hitView isKindOfClass:[AnimalView class]]) {
        AnimalView *animal = (AnimalView *)hitView;
        [animal doSomething];
    }
}

However, nothing happened when I clicked on the animal. When I checked the class of hitView by NSLog(@"%@", [hitView class]), it always shows UIView instead of AnimalView. Is it true that the AnimalView changed to a UIView when it is added onto the ViewController? Is there any way I can get back the original class of a custom class?
