We are trying to implement MKMapView in iOS application.I got the mapView with the given locations and pins.When I tap on these pins I am getting the title and subtitle also.Now I want to include a detail Disclosure button in this view in which the title and subtitle are displayed.For that I used the below given code[MKPinannotation detail disclosure button - present new view is going inside the first method but it is not showing the detailDisclosureButton.
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"pinView"];
if (!pinView) {
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"pinView"] autorelease];
pinView.pinColor = MKPinAnnotationColorRed;
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinView.rightCalloutAccessoryView = rightButton;
} else {
pinView.annotation = annotation;
}
return pinView;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped
{
}
Now what can I do?Anyone please take a look and help me...
-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation {
pinView = nil;
if(annotation != map.userLocation)
{
NSString *defaultPinID =#"com.invasivecode.pin1";
pinView = (MKPinAnnotationView *)[map dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinView == nil ) pinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
UIButton *btnGo = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[btnGo addTarget:self action:#selector(goToLocation:) forControlEvents:UIControlEventTouchUpInside];
pinView.rightCalloutAccessoryView=btnGo;
pinView.canShowCallout = YES;
pinView.animatesDrop = YES;
pinView.draggable=NO;
}
else {
[map.userLocation setTitle:#"I am here"];
}
return pinView;
}
Declare this in .h file
MKPinAnnotationView *pinView
please try setting the frame for rightButton i.e
rightButton.frame = CGRectMAke (x,y,width,height);

Hope someone can help, I'm trying to implement dropping one single Pin on a mapView. But I want the pin to be able to be dragged around and and dropped and for this annotation to be separate from the annotation for the user's location. Whilst the below code works, it creates duplicate pins for a user's touch and the pins can not be dragged around:
- (void)dropPinFromPress:(UIGestureRecognizer *)recognizer {
// Add Pin from User's Touch
if (recognizer.state != UIGestureRecognizerStateBegan) {
return;
}
// convert touched position to map coordinate
CGPoint userTouch = [recognizer locationInView:self.mapView];
CLLocationCoordinate2D mapPoint = [self.mapView convertPoint:userTouch toCoordinateFromView:self.mapView];
// Add Pin from user's touch
Annotation *pin = [[Annotation alloc]initWithLocation:mapPoint];
[self.mapView addAnnotation:pin];
}
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{
MKAnnotationView *a = [ [ MKAnnotationView alloc ] initWithAnnotation:annotation reuseIdentifier:#"currentloc"];
// a.title = #"test";
if ( a == nil )
a = [ [ MKAnnotationView alloc ] initWithAnnotation:annotation reuseIdentifier: #"currentloc" ];
NSLog(#"%f",a.annotation.coordinate.latitude);
NSLog(#"%f",a.annotation.coordinate.longitude);
CLLocation* currentLocationMap = [[[CLLocation alloc] initWithLatitude:a.annotation.coordinate.latitude longitude:a.annotation.coordinate.longitude] autorelease];
[self coordinatesToDMS:currentLocationMap];
MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:a reuseIdentifier:#"currentloc"];
if(a.annotation.coordinate.longitude == mapView.userLocation.coordinate.longitude || a.annotation.coordinate.latitude == mapView.userLocation.coordinate.latitude )
{
if ([annotation isKindOfClass:MKUserLocation.class])
{
//user location view is being requested,
//return nil so it uses the default which is a blue dot...
return nil;
}
//a.image = [UIImage imageNamed:#"userlocation.png"];
//a.pinColor=[UIColor redColor];
}
else
{
// annView.image =[UIImage imageNamed:#"map-pin.png"];
//PinFirst=FALSE;
//annView.pinColor = [UIColor redColor];
// annView.annotation=annotation;
}
annView.animatesDrop = YES;
annView.draggable = YES;
annView.canShowCallout = YES;
return annView;
}

I am working on an mapkit app which drops pins on the map on certain locations (code at the end)
I have also added code for the callout. However, depending on which pin was tapped I was attemping to load a different views and I have no found any way to do oddly.
I placed a breakpoint and while stepping thru I noticed that there was a line which read.
"annotation.title=#"myhome"; so i was wondering if there way someway i could say what to call depending on which annotation was tapped.
Thanks

You could set tags say 1 for left and 2 for right accessory view. And in your calloutAccessoryControlTapped method, do like:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
if ([control tag] == 1) {
NSLog(#"tapped left accessory");
}
else if ([control tag] == 2) {
NSLog(#"tapped right accessory");
}
}
HI I have requirement to Implement Next and Previous functionality in the MKMapAnnotationView as shown in the Image.I have got reference from Here for making custom annotation but how can i change the next or previous annotation by clicking Next and Previous button.Please provide some Hint or idea regarding this.I am stack at this point.
For that you can use the rightCalloutAccessoryView and leftCalloutAccessoryView.
Here an example how to use the rightCalloutAccessoryView.
-(MKAnnotationView*)mapView:(MKMapView *)mapView viewForAnnotation: (id<MKAnnotation>)annotation {
if ([annotation isKindOfClass: [MKUserLocation class]]) {
return nil;
}
static NSString* AnnotationIdentifier = #"AnnotationIdentifier";
MKPinAnnotationView *pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
[pinView setCanShowCallout:YES];
if([annotation isKindOfClass:[ASPinAnnotation class]])
{
[pinView setPinColor:MKPinAnnotationColorRed];
}
else if([annotation isKindOfClass:[ASAddAutomatPin class]])
{
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton setTitle:[annotation title] forState:UIControlStateNormal];
[pinView setRightCalloutAccessoryView:rightButton];
[pinView setPinColor:MKPinAnnotationColorPurple];
}
And to get notified when a calloutAccessoryView is tapped you have to use this function in your delegate:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
if([(UIButton*)control buttonType] == UIButtonTypeDetailDisclosure)
{
ASAddViewController *addController = [[ASAddViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addController];
[addController setDelegate:self];
[self.controller presentViewController:navController animated:YES completion:nil];
}
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
NSLog(#"I'm Working");
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[userPins class]]) {
userPins *location = (userPins *) annotation;
MKPinAnnotationView *annotationView = (MKPinAnnotationView *) [_mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil) {
annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
} else {
annotationView.annotation = annotation;
}
annotationView.enabled = YES;
annotationView.canShowCallout = YES;
if ([location.name compare:#"LARCENY"] == NSOrderedSame) {
annotationView.pinColor = MKPinAnnotationColorGreen;
}
return annotationView;
}
return nil;
}
This code not working. I'm adding pins from JSON. I see red pins but I can't see nslog(I'm working). Any ideas?
You need to set the mapView's delegate in viewDidLoad or in the nib or wherever you are creating it.
I am working with MKPinAnnotationView annotations pins over a MKMapView. Into the view that I am developing, there is a map centered on a pin. When I call the view the pin drops down and if I make a click over it, it shows the annotation information (canShowCallout = YES). How I can get this callout just when I open the view? Without making a click over the annotation pin.
Thanks for reading.
Edited:
I am using this code.
- (void)viewDidLoad {
[super viewDidLoad];
AddressAnnotation *annotation = [[[AddressAnnotation alloc] initWithCoordinate:self.currentAnnotationCoordinate] autorelease];
[self.mapView addAnnotation:annotation];
[self zoomCoordinate:self.currentAnnotationCoordinate];
}
- (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation {
// If it's the user location, just return nil.
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
else { // Handles the other annotations.
// Try to dequeue an existing pin view first.
static NSString *AnnotationIdentifier = #"AnnotationIdentifier";
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier];
if (!pinView) {
// If an existing pin view was not available, creates one.
MKPinAnnotationView *customPinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier] autorelease];
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;
// Adds a detail disclosure button.
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;
} else
pinView.annotation = annotation;
}
return nil;
}
- (void)mapViewDidFinishLoadingMap:(MKMapView *)theMapView {
AddressAnnotation *annotation = [[[AddressAnnotation alloc] initWithCoordinate:self.currentAnnotationCoordinate] autorelease];
for (id<MKAnnotation> currentAnnotation in mapView.annotations) {
if ([currentAnnotation isEqual:annotation]) {
[mapView selectAnnotation:currentAnnotation animated:FALSE];
}
}
}
Edited:
Calling didAddAnnotationViews: instead of mapViewDidFinishLoadingMap: (as aBitObvious has commented), it works fine.
- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views {
id<MKAnnotation> myAnnotation = [self.mapView.annotations objectAtIndex:0];
[self.mapView selectAnnotation:myAnnotation animated:YES];
}

You want to call [mapView selectAnnotation:].
