With iOS 7 this works fine. - (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { CustomMapAnnotation *annotation = (CustomMapAnnotation *)view.annotation; if([annotation isKindOfClass:[CustomMapAnnotation class]]) { CustomMapCalloutView *calloutView = [CustomMapCalloutView new]; calloutView.translatesAutoresizingMaskIntoConstraints = NO; calloutView.titleLabel

问题 In my app I'm rotating the MapView according to the device heading, I have only one annotation and i'm rotating it's pin and it's pinView too. My rotation method is inside the next function - (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading { if (newHeading.headingAccuracy < 0) return; CLLocationDirection theHeading = ((newHeading.trueHeading > 0) ? newHeading.trueHeading : newHeading.magneticHeading); lastHeading = theHeading; [self rotateImage:self

问题 As you can see in the image below that all annotations have same image and discount which is not correct, they should have different image and discount . How can I fix this? I am using a custom annotation class with discountStr and 'imgPathStr' property and the following code. -(void) connectionDidFinishLoading: (NSURLConnection *) connection { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; _adResultDict = [NSJSONSerialization JSONObjectWithData:_adResultData options

问题 For some odd reason the detail button somehow stopped appearing: - (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation { MKPinAnnotationView *pinAnnotation = nil; if(annotation != mapView.userLocation) { MKPinAnnotationView *pinAnnotation = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"sadasdasd"]; if ( pinAnnotation == nil ){ pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@

问题 I am using the below code to fetch location information via Geocoding and then add a map pin to a Google Map View. The code uses a For loop to cycle through each place in my database.
