In my application I am using mapkit. All the time I have more than one annoatations on the map. In the callout i have placed the detailDisclosureButton. On the click of this button I want to load new viewController. How to do this?
Thanks in advance.
In - (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id )annotation delegate add a disclosure button as -
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[infoButton addTarget:self action:#selector(infoButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
pinView.rightCalloutAccessoryView = infoButton;
and in its action method -
-(IBAction) infoButtonPressed:(id) sender
{
DetailViewController *dvc = [[DetailViewController alloc] init];
[self.navigationController pushViewController:dvc animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation
{
//Some code here
pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
return pinView;
}
And make use of the following delegate method to get the button action
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
// code to show details view
}
I would check here: Modal View Controller Reference to see how to move from one view to another. When the detailDisclosureButton is pressed, set up the viewController you want to move to, and use the methods described in the link. Hope that helps!

I would like to have another view loaded when I tap on the disclosure button in my map callout.
I added the button to the callout using the following in the initWithAnnotation method of my AnnotationView implementation file (I am only showing the relevant code):
- (id)initWithAnnotation:(id<MKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier
{
self.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
}
I also added the following controllTapped method to my MapViewController implementation file for detecting when the disclosure button has been tapped:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
DetailViewController *dvc = [[DetailViewController alloc] init];
[self.navigationController pushViewController:dvc animated:YES];
}
I also created a new detailedDisclosure class with an .XIB for a UI. This is the view I want to load when the user taps the disclosure button.
Why, then, does nothing happen when the user taps the disclosure button?
UIButton *btnGo = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[btnGo addTarget:self action:#selector(goToLocation:) forControlEvents:UIControlEventTouchUpInside];
pinView.rightCalloutAccessoryView=btnGo;
-(void) goToLocation:(UIButton *) sender
{
}
You have to use MKMapView delegate method for this purpose like following, for identifying your CustomAnnotationClass:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
id <MKAnnotation> annotation = [view annotation];
if ([annotation isKindOfClass:[CustomAnnotationClass class]])
{
DetailViewController *dvc = [[DetailViewController alloc] init];
[self.navigationController pushViewController:dvc animated:YES];
}
}
Let me kno, If you get it to work.
I have a map view and there are 10 store locations which data comes via webservice. I just want to push to my detail view to show address, telephone and other informations of the clicked store.
I need to pass data to my detailview when user tapped or touch up inside to a annotation on mapkit. There are 10 annotations in my mapview and first I want to know, how can I understand or how can I get the annotationID of which annotation is clicked?
this is the method I return pins
- (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.animatesDrop=YES;
pinView.canShowCallout=YES;
pinView.pinColor=MKPinAnnotationColorPurple;
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton setTitle:annotation.title forState:UIControlStateNormal];
[rightButton addTarget:self
action:#selector(showDetails:)
forControlEvents:UIControlEventTouchUpInside];
pinView.rightCalloutAccessoryView = rightButton;
return pinView;
}
/* and my action method for clicked or tapped annotation: */
- (IBAction)showDetails:(id)sender{
NSLog(#"Annotation Click");
[[mtMap selectedAnnotations]objectAtIndex:0];
magazaDetayViewController *detail = [[magazaDetayViewController
alloc]initWithNibName:#"magazaDetayViewController" bundle:nil];
detail.sehir=#"";
detail.magazaAdi=#"";
detail.adres=#"";
detail.telefon=#"";
detail.fax=#"";
[self.navigationController pushViewController:detail animated:YES];
}
if i can just get the clicked annotation index no i can fill detail properties with my array.
if this is impossible is there any other way to do it?
First in your annotaion view delegat make a button to go in detail view like bellow:
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{
MKPinAnnotationView *mypin = [[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:#"current"];
mypin.pinColor = MKPinAnnotationColorPurple;
mypin.backgroundColor = [UIColor clearColor];
UIButton *goToDetail = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
mypin.rightCalloutAccessoryView = myBtn;
mypin.draggable = NO;
mypin.highlighted = YES;
mypin.animatesDrop = TRUE;
mypin.canShowCallout = YES;
return mypin;
}
Now use the following delegate whenever the button in annotationView will get tapped the following delegate will be called from where you can easly get which particular annotaion's button is tapped
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
{
annotation *annView = view.annotation;
detailedViewOfList *detailView = [[detailedViewOfList alloc]init];
detailView.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
detailView.address = annView.address;
detailView.phoneNumber = annView.phonenumber;
[self presentModalViewController:detailView animated:YES];
}
here annotaion is a class importing MKAnnotaion.h and address and phonenumber are properties of annotaion class you can make many more while the address and phoneNumber properties of detailView class are strong. So that you can pass values. Hope this will help you!
Bellow is Delegate method of MapView......
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
}
when user tap annotation pin above method call automaticaly if method define in .m file nut first declare MKMapViewDelegate delegate in .h file
and also you can get title or subtitle and id from google place API....
link is...
https://developers.google.com/maps/documentation/places/
for(int i=0; i<[arrLat count];i++) {
CLLocationCoordinate2D theCoordinate1;
konumpin* myAnnotation1=[[konumpin alloc] init];
theCoordinate1.latitude = [[arrLong objectAtIndex:i] doubleValue];
theCoordinate1.longitude = [[arrLat objectAtIndex:i] doubleValue];
myAnnotation1.coordinate=theCoordinate1;
myAnnotation1.title=[arrMagaza objectAtIndex:i];
[annotations addObject:myAnnotation1];
}
[mtMap addAnnotations:annotations];
I want to navigate to next class through tap on MKAnnotationView on MKMapView. How can I do this plz give some sample code for this.
I had done this code..explained below..
- (void)mapView:(MKMapView *)mapView1 didSelectAnnotationView:(MKAnnotationView *)customAnnotationView
{
//Here Push to another view controller
}
One problem is that when clicking on one item, this method calls and It will navigate to other class but when I come back and again tap on the same item this method not called.
Please help me to solve me this problem...
Thanks in advance...
you need to implement this method:-
edited:-
you need to implement following method.
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
NSLog(#"touch");
[mapView deselectAnnotation:view animated:NO];
firstVC *aa=[[[firstVC alloc]initWithNibName:#"firstVC" bundle:nil] autorelease];
[[self navigationController] pushViewController:aa animated:YES];
}
-(void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
NSLog(#"notouch");
firstVC *aa=[[[firstVC alloc]initWithNibName:#"firstVC" bundle:nil] autorelease];
[[self navigationController] pushViewController:aa animated:YES];
}
previous:-
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
CompanyDetail *detail = [[CompanyDetail alloc] initWithNibName:#"CompanyDetail" bundle:nil];
[self.navigationController pushViewController:detail animated:YES];
}
Make sure you do
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
in your
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation method
I have a map with only one annotation.I created a simple class which I want it to show when the user clicks on the annotation.The problem is that when I click on the annotation nothing happens.
Here is my code:
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark{
NSLog(#"Reverse Geocoder completed");
mPlacemark=placemark;
[mapView addAnnotation:placemark];
}
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"currentloc"];
annView.animatesDrop=TRUE;
//create UIButton for annotation
UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
//NSInteger annotationValue = [self.annotations indexOfObject:annotation];
[detailButton addTarget:self action:#selector(showDetailView:) forControlEvents:UIControlEventTouchUpInside];
annView.rightCalloutAccessoryView=detailButton;
return annView;
}
-(void)showDetailView:(id)sender{
NSLog("inside the stupid method");
MyDetailViewController *detailView=[[MyDetailViewController alloc] initWithNibName:#"MyDetailViewController" bundle:nil];
[[self navigationController] pushViewController:detailView animated:YES];
[detailView release];
}
My showDetailView function never gets called.Please help me.I'm new to iphone and I might forget a simple thing.Thanks
Still not working!!!!
First, check that the map view's delegate is set otherwise your viewForAnnotation method will not get called.
Next, the accessory button appears on the annotation's callout which will only appear if you set canShowCallout:
annView.canShowCallout = YES;
Next, instead of using your own method to handle the button action, it's much better to use the map view's own calloutAccessoryControlTapped delegate method which gets called when tapping an accessory:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"inside the stupid method");
//Here, the annotation tapped can be accessed using view.annotation
}
Remove the [detailButton addTarget... line from viewForAnnotation.
Also note your NSLog in the showDetailView method is missing the leading # which will result in a crash when the method does get called.
Another thing is you should use dequeueReusableAnnotationViewWithIdentifier in viewForAnnotation to enable annotation view re-use.
Example as requested:
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{
static NSString *annReuseId = #"currentloc";
MKPinAnnotationView *annView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:annReuseId];
if (annView == nil)
{
annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:annReuseId];
annView.animatesDrop = YES;
annView.canShowCallout = YES;
UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annView.rightCalloutAccessoryView=detailButton;
}
else {
annView.annotation = annotation;
}
return annView;
}
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"calloutAccessoryControlTapped: annotation = %#", view.annotation);
MyDetailViewController *detailView=[[MyDetailViewController alloc] initWithNibName:#"MyDetailViewController" bundle:nil];
//here, can set annotation info in some property of detailView
[[self navigationController] pushViewController:detailView animated:YES];
[detailView release];
}
Ok. If you are using storyboards, you need to create a segue between the map view controller and then where the below code exists:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"calloutAccessoryControlTapped: annotation = %#", view.annotation);
MyDetailViewController *detailView=[[MyDetailViewController alloc] initWithNibName:#"MyDetailViewController" bundle:nil];
//here, can set annotation info in some property of detailView
[[self navigationController] pushViewController:detailView animated:YES];
[detailView release];
}
Use the following code instead:
NSLog(#"calloutAccessoryControlTapped: annotation = %#", view.annotation);
[self performSegueWithIdentifier:#"DetailViewController" sender:self];
This will give you the movement to the detailed view.
write your function like this:
-(IBAction)showDetailView:(id)sender{
NSLog("inside the stupid method");
MyDetailViewController *detailView=[[MyDetailViewController alloc] initWithNibName:#"MyDetailViewController" bundle:nil];
[[self navigationController] pushViewController:detailView animated:YES];
[detailView release];
}
you have to set the map delegate to self like this,
mapview.delegate=self; (if your calling the method in same page)
if you don't assign the delegate in your code the respective methods won't be called, so check if you have the above mentioned line.
Replace -(IBAction)showDetailView:(UIView*)sender with following...
-(void)showDetailView:(id)sender
In my MapView i have pin dropped on certain locations and now i want to display some title on these pin annotation and make it clickable so that on click i can push another view.
Please help !!!!
This is the code snippet:
Custom Annotation View using this method
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
if (annotation == mapView.userLocation) return nil;
MKPinAnnotationView *pin = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier: #"asdf"];
if (pin == nil)
{
pin = [[[MKPinAnnotationView alloc] initWithAnnotation: annotation reuseIdentifier: #"asdf"] autorelease];
}
else
{
pin.annotation = annotation;
}
pin.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pin.pinColor = MKPinAnnotationColorRed;
pin.animatesDrop = YES;
[pin setEnabled:YES];
[pin setCanShowCallout:YES];
return pin;
}
Delegate method which get's called when you tap on the button
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
//DetailPg=[[BookMarksDetail alloc]initWithNibName:#"BookMarksDetail" bundle:nil];
//DetailPg.selectRest =[view.annotation title]; //In addition, to get the Title of the AnnotationView.
//DetailPg.m=1;
//[self.navigationController pushViewController:DetailPg animated:YES];
//[DetailPg release];
}
The answers to this are all provided in Apples Docs I suggest you read them more closely. However to have a call out all you need to do is set the title property.
For buttons and such you need to use the MapView Delegate method:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
_pin.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
Apple suggests reusing annotations this is something you will need to take into account.
