IOS CustomCallout does not get removed from the view - ios

Question

I have a custom callout loaded from a xib file.
It loads and displays correctly.
The problem is that the callouts will not remove from the view.
I recently added the 'tag = 999' so i could try to track the subview, no joy, it never sees a tag with a value of 999.
I have tried every possible 'removeFromSuperview' combination I could find.
The 'handleTap method is getting called ok.
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView
*)view {
if ([view.annotation isKindOfClass:[MKUserLocation class]]) {
return;
}
UIView *customCalloutView = [[[NSBundle mainBundle] loadNibNamed:#"CustomXibCallout" owner:self options:nil]objectAtIndex:0];
customCalloutView.tag = 999;
customCalloutView.backgroundColor = [UIColor whiteColor];
customCalloutView.alpha = 0.9;
customCalloutView.layer.cornerRadius = 10.0f;
CGPoint offset = CGPointAdd(customCalloutView.center,(CGPointMake(-100, -150)));
customCalloutView.center = offset;
[view addSubview: customCalloutView];
}
- (void)handleTap:(UITapGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateEnded) {
for (UIView *subView in self.view.subviews) {
if (subView.tag == 999) {
[subView removeFromSuperview];
}
}
}
}

Answer 1

First, you are adding customCalloutView as a subview of an MKAnnotationView -- not as a subview of self.view. So looping through self.view.subviews looking for 999 isn't going to work.
Depending on the hierarchy... if (MKAnnotationView *)view is a subview of (MKMapView *)mapView, which is a subview of self.view ... you could try:
UIView *v = [self.view viewWithTag:999];
[v removeFromSuperview];
But.... I think a better route is to know where the view is in the hierarchy. In - (void)handleTap:(UITapGestureRecognizer *)sender, sender is the gesture. You can get the view that sent the tap with:
sender.view
So, if you know the gesture is being sent by the MKAnnotationView, you could keep assigning the 999 tag and change your handler to:
- (void)handleTap:(UITapGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateEnded) {
UIView *v = [sender.view viewWithTag:999];
[v removeFromSuperview];
}
}

Answer 2

- (void)handleTap:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
MKAnnotationView *av = (MKAnnotationView *)sender.view;
if (av.tag == 999) {
[av removeFromSuperview];
}
}
}
