I connect annotation with UITapGestureRecognizer. I want to detect touch.
if ([annotation isKindOfClass:[Annotation class]])
{
NSString * annotationIdentifier = @"UserAnnotationIdentifier";
CustomAnnotationView * customAnnotationView = (CustomAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:annotationIdentifier];
if (!customAnnotationView)
{
customAnnotationView = [[CustomAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:annotationIdentifier];
UITapGestureRecognizer *tapGesture =
[[UITapGestureRecognizer alloc] initWithTarget:self
action:@selector(calloutTapped:)];
[customAnnotationView addGestureRecognizer:tapGesture];
I use the code bottom, but it caused error in compilation
-(void) calloutTapped:(id) sender {
id<MKAnnotation> annotation = ((MKAnnotationView*)sender.view).annotation;
ERROR: property view not found on object of type __strong id
Change:
-(void) calloutTapped:(id) sender
to:
-(void) calloutTapped:(UITapGestureRecognizer *) sender
then the sender
would have the view
property or first cast the sender
to UITapGestureRecognizer
.
To cast correctly:
-(void) calloutTapped:(id) sender {
UITapGestureRecognizer *tapGesture = (UITapGestureRecognizer *)sender;
MKAnnotationView *sendersView = (MKAnnotationView *)tapGesture.view;
id<MKAnnotation> annotation = sendersView.annotation;
}
