PO- (MKAnnotationView *)mapView not getting called
text
Body
copied!<p>In my code, the <code>- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation</code> method is not getting called. I don know why. Can anyone please help me?</p> <p>Below is my code:</p> <pre><code>- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@","]; NSLog(@"pin map"); if(pinView == nil) { pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@""]; pinView.animatesDrop = YES; pinView.canShowCallout = YES; UIImage *image = [UIImage imageNamed:@"ann.png"]; CGRect resizeRect; resizeRect.size = image.size; CGSize maxSize = CGRectInset(self.view.bounds, [map annotationPadding], [map annotationPadding]).size;*/ maxSize.height -= self.navigationController.navigationBar.frame.size.height + [map calloutHeight]; if (resizeRect.size.width > maxSize.width) resizeRect.size = CGSizeMake(maxSize.width, resizeRect.size.height / resizeRect.size.width * maxSize.width); if (resizeRect.size.height > maxSize.height) resizeRect.size = CGSizeMake(resizeRect.size.width / resizeRect.size.height * maxSize.height, maxSize.height); resizeRect.origin = (CGPoint){0.0f, 0.0f}; UIGraphicsBeginImageContext(resizeRect.size); [image drawInRect:resizeRect]; UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); pinView.image = resizedImage; pinView.opaque = NO; UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside]; pinView.rightCalloutAccessoryView = rightButton; if (annotation == mapView.userLocation) { return nil; } return pinView; } else { pinView.annotation = annotation; } return pinView; } </code></pre> <p>This is how I am adding the annotations to the map:</p> <pre><code>-(void) Annotations:(int)i { /*NSString* address = [mpartyDetail objectAtIndex:i]; address = [[address componentsSeparatedByCharactersInSet: [NSCharacterSet whitespaceCharacterSet]] componentsJoinedByString: @""]; NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", address]; NSLog(@"nsstring %@",urlString); NSString *locationString = [[[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:urlString]] autorelease]; NSLog(@"location string %@",locationString); NSArray *latlng = [locationString componentsSeparatedByString:@","]; NSLog(@"the latlng %@",latlng); float lat = [[latlng objectAtIndex:2] floatValue]; float lng = [[latlng objectAtIndex:3] floatValue]; */ NSLog(@"ann"); lat = [[latiArray objectAtIndex:i]floatValue]; lng = [[longiArray objectAtIndex:i]floatValue]; CLLocationCoordinate2D newCoord = {lat,lng}; mapAnnotations* annotation = [[mapAnnotations alloc] initWithCoordinate:newCoord]; [mapView addAnnotation:annotation]; } </code></pre> <p>mapAnnotations is another class. The below code shows the method of that class which is getting called:</p> <pre><code>- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate{ NSLog(@"the cor"); self = [super init]; if (self != nil) { NSLog(@"in"); _coordinate = coordinate; } return self; } </code></pre> <p>The idea is that I add annotations when the user presses on the map and the user can give any title to that pin. I need a callout to show the title entered by the user. The annotations are getting added. But I am not able to get the callout as this method is not getting called.</p>
