It always gives NSLog for image pressed 0. I'm don't understand what it is exactly what I'm doing wrong. It never gives me the number of the image I'm pressing. Even when I try to save the image I tap on it always saves the very last image.
- (void)viewDidLoad
{
UIScrollView *imageScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
imageScrollView.delegate = self;
imageScrollView.pagingEnabled = YES;
for (int i = 0; i < 61; i++) {
CGFloat xOrigin = i * self.view.frame.size.width;
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton addTarget:self action:#selector(dismissView:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(xOrigin, 10, 60, 35);
[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
myButton.layer.borderWidth = 2;
myButton.layer.borderColor = [[UIColor whiteColor] CGColor];
[myButton setTitle:#"Done" forState:UIControlStateNormal];

Because you never set the tag for the view so it defaults to 0. And seriously, how many times are you going to ask the same question? You've been given quite a lot of good feedback, use it.
