MKMapView -> display a button for my location
I have a MKMapView
implemented with these lines of source code (my location is a blue bullet, the other one's are purple pins):
- (MKAnnotationView *)mapView:(MKMapView *)mapViewLocal viewForAnnotation:(id <MKAnnotation>)annotation {
if (annotation == mapViewLocal.userLocation) {
mapViewLocal.userLocation.title = @"Test";
[mapViewLocal setRegion:MKCoordinateRegionMakeWithDistance(mapViewLocal.userLocation.coordinate, 1000, 1000) animated:YES];
return nil;
}
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapViewLocal dequeueReusableAnnotationViewWithIdentifier:@"Pin"];
if(pinView == nil) {
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"Pin"] autorelease];
pinView.pinColor = MKPinAnnotationColorPurple;
pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinView.animatesDrop = NO;
pinView.canShowCallout = YES;
} else {
pinView.annotation = annotation;
}
return pinView;
}
The purple pins have a detail disclosure button, but my annotation does not开发者_StackOverflow中文版 have one. How can I set such a button?
And that is the method where I can do somethin a button is pressd:
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
How could I differentiate between my location and all other one's, because I need a different handling. Is there another delegate or do I have to make some kind of if clause?
in your didUpdateToLocation
write something like
AddressAnnotation *myAnnotation = [[AddressAnnotation alloc] initWithCoordinate:currentLocation];
myAnnotation.title = @"You are here";
[self.mapView addAnnotation:myAnnotation];
And Then
Something Like
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
// try to dequeue an existing pin view first
static NSString* annotationIdentifier = @"annotationIdentifier";
NSString *titlestr = annotation.title;
MKPinAnnotationView* pinView = (MKPinAnnotationView *)
[mapView dequeueReusableAnnotationViewWithIdentifier:annotationIdentifier];
MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:nil] autorelease];
if (!pinView)
{
// if an existing pin view was not available, create one
// MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
//initWithAnnotation:annotation reuseIdentifier:annotationIdentifier] autorelease];
if([titlestr isEqualToString:@"You are here"])
{
customPinView.pinColor = MKPinAnnotationColorGreen;
NSLog(@"customPinView.pinColor = MKPinAnnotationColorGreen;");
}
else{
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.selected = TRUE;
NSLog(@"customPinView.pinColor = MKPinAnnotationColorPurple;");
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self
action:@selector(ShowStoreDetail:)
forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
}
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;
return customPinView;
}
else
{
pinView.annotation = annotation;
if([titlestr isEqualToString:@"You are here"])
{
customPinView.pinColor = MKPinAnnotationColorPurple;
NSLog(@"customPinView.pinColor = MKPinAnnotationColorGreen;");
}
else{
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.selected = TRUE;
NSLog(@"customPinView.pinColor = MKPinAnnotationColorPurple;");
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self
action:@selector(ShowStoreDetail:)
forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
}
}
return pinView;
return nil;
}
