Firstly you create a tap gesture recognizer and then add it to the view dot. UIView dot already has the tag assigned.
UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self
action:@selector(gotoZone:)];
[dot addGestureRecognizer:tapped];
Later, the problem in gotoZone: method is how to identify which UIView dot did the user tap? Here’s how we did it.
Setup a comparison and then cast the tap, associate the UIView with that tap, and voila, the row is the tag of that view.
if ([sender isKindOfClass:[UITapGestureRecognizer class]]) {
UITapGestureRecognizer *tap = (UITapGestureRecognizer *)sender;
UIView *view = tap.view;
row = view.tag;
}
