has somebody an idea why i can't force the mapView callout to use a detailDisclosureBtn instead of infoButton?
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString *identifier = #"HPIPAnnotation";
if ([annotation isKindOfClass:[CoreCityAnnotation class]])
{
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [_mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
UIButton *disclosureButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.canShowCallout = YES;
annotationView.animatesDrop = YES;
annotationView.rightCalloutAccessoryView = disclosureButton;
return annotationView;
}
return nil;
}
Thats my implementation of the delegate.
The button images for detailDisclosure type and infoLight/infoDark are the same.

PREAMBLE
I have implemented a map annotation using MKMapView and MapAnnotation. When tapped a title view appears as depicted in the following image.
I have used the following LOC to implement said map annotation:
// VENUE 1 PIN.
CLLocationCoordinate2D venue1Location = CLLocationCoordinate2DMake(-27.5, 153.5);
MapAnnotation *venue1Pin = [[MapAnnotation alloc] initWithTitle:#"1 ONE ST" Location:venue1Location];
VIEW FOR ANNOTATION DELEGATE METHOD:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MapAnnotation class]])
{
MapAnnotation *venueLocationAnnotation = (MapAnnotation *)annotation;
MKAnnotationView *venueLocationAnnotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:#"customAnnotation"];
venueLocationAnnotationView.rightCalloutAccessoryView.hidden = YES;
if (venueLocationAnnotationView == nil)
venueLocationAnnotationView = venueLocationAnnotation.annotationView;
else
venueLocationAnnotationView.annotation = annotation;
return venueLocationAnnotationView;
}
else
{
return nil;
}
}
QUESTION
How do I remove the information button from the aforementioned map annotation title view ?
You can use following statement:
You have to implement following delegate method for this:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
...
venue1Pin.rightCalloutAccessoryView = nil;
...
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:nil];
annotationView.canShowCallout = YES;
annotationView.rightCalloutAccessoryView.hidden=YES;
return annotationView;
}
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[MKPointAnnotation class]])
{
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:#"yourPinIdentifier"];
if (!pinView)
{
pinView.rightCalloutAccessoryView.hidden=YES;
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
}
return pinView;
}
}
I'm trying to create a custom map callout that looks like so:
As you can see, I need custom pins and custom callouts. The color of the pins are based on a rating as is the color of the circle in the callout.
Here's the code that I have so far:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[CustomAnnotation class]])
{
static NSString *identifier = #"CustomAnnotation";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[self.map dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil)
{
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
annotationView.enabled = YES;
annotationView.canShowCallout = NO;
annotationView.animatesDrop = NO;
}
else
{
annotationView.annotation = annotation;
}
CustomAnnotation *myAnnotation= (CustomAnnotation *)annotation;
// Based on the score, set the pin image
if ([myAnnotation.score intValue] == 1)
{
annotationView.image = [UIImage imageNamed:#"dot_purple_xsmall.png"];
}
else if (...)
{
// and so on...
}
return annotationView;
}
return nil;
}
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
if (![view.annotation isKindOfClass:[MKUserLocation class]])
{
CustomCalloutView *callout = CustomCalloutView *)[[[NSBundle mainBundle]loadNibNamed:#"MyCallout" owner:self options:nil] objectAtIndex:0];
CGRect calloutViewFrame = callout.frame;
calloutViewFrame.origin = CGPointMake(-calloutViewFrame.size.width / 2 + 15, -calloutViewFrame.size.height);
callout.frame = calloutViewFrame;
// TODO: Set the outlets of the xib
callout.nameLabel.text = #"Testing";
[view addSubview:callout];
}
}
- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
for (UIView *subView in view.subviews)
{
[subView removeFromSuperview];
}
}
The custom pins work fine but when I tap on a pin, all I get is a black view. The app also uses a Navigation and Tab Controller.
Here is only one delegate for it.
#pragma mark - Map Delegate
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString *reuseId = #"annotation";
MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[mapView
dequeueReusableAnnotationViewWithIdentifier:reuseId];
if (annotationView == nil)
{
annotationView = [[MKPinAnnotationView alloc]
initWithAnnotation:annotation
reuseIdentifier:reuseId];
}
else
{
//Update view's annotation reference
//because we are re-using view that may have
//been previously used for another annotation...
annotationView.annotation = annotation;
}
annotationView.image = [UIImage imageNamed:#"spotcrewcellicon_image.png"];
return annotationView;
}
#end
You are probably trying to perform operations on the annotation for the user's location, a common cause of crashes in viewForAnnotation:
if([annotation isKindOfClass:[MKUserLocation class]])
{
return nil; // Use default system user-location view.
}
should solve your problem.
I want to avoid to display a callout when I tap a MKAnnotation, just to display the pin, and when I tap, I want nothing happens.
Thanks
Try like this .
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"sample"];
annView.canShowCallout = NO;
return annView;
}
Hope this code is useful for you.
This will help you.
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
static NSString *reuseId = #"pin";
MKPinAnnotationView *pinV = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseId];
if (pinV == nil)
{
pinV = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseId];
pinV.canShowCallout = NO; // You have to add this.
}
return pinV;
}
I want to check if the annotation is clicked:
So it goes from this:
To :
Here's my code that shows the annotation:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[MyLocation class]]) {
MKAnnotationView *annotationView = (MKAnnotationView *) [_mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
annotationView.image = [UIImage imageNamed:#"arrest.png"];//here we use a nice image instead of the default pins
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
} else {
annotationView.annotation = annotation;
}
return annotationView;
}
return nil;
}
the rightCalloutAccesoryView is a blue button inside the callout. But i need to hide something when the user clicks on the annotation.
Does anyone know how to check this/do this?
Thanks is advance
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
//do your code
}
