text
Body
copied!<p>I'm using Parse.com as a backend and i want to show Geopoints on my map. Every Geopoint is also connected with a database boolean field true or false.</p> <p>How can I show a green pins colour for the "true" gepoint and red pins for the "false" Geopoint?</p> <p>Here is code for the <strong>MapViewController.m</strong></p> <pre><code>@property (weak, nonatomic) IBOutlet MKMapView *mapView; </code></pre> <p>I have a function to perform the query against the parse.com database to return me all location data. It is called within the viewDidLoad Method.</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; [self getAllStations]; } </code></pre> <p>Then I set the annotationView like this:</p> <pre><code>#pragma mark - MapViewDelegate - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)geoPointAnnotation { static NSString *MapViewAnnotationIdentifier = @"Places"; MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:MapViewAnnotationIdentifier]; if (geoPointAnnotation == mapView.userLocation) { return nil; } else { annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:geoPointAnnotation reuseIdentifier:MapViewAnnotationIdentifier]; annotationView.pinColor = MKPinAnnotationColorGreen; annotationView.canShowCallout = YES; annotationView.draggable = YES; annotationView.animatesDrop = YES; } return annotationView; } </code></pre> <p>Here is the Code for the <strong>MapViewAnnotation.m (Object):</strong></p> <pre><code>#import "MapViewAnnotation.h" #import "Parse/Parse.h" @interface MapViewAnnotation () @property (nonatomic, strong) PFObject *object; @end @implementation MapViewAnnotation #pragma mark - Initialization - (id)initWithObject:(PFObject *)aObject { self = [super init]; if (self) { _object = aObject; PFGeoPoint *geoPoint = self.object[@"location"]; [self setGeoPoint:geoPoint]; } return self; } - (void)setGeoPoint:(PFGeoPoint *)geoPoint { _coordinate = CLLocationCoordinate2DMake(geoPoint.latitude, geoPoint.longitude); NSString *streetName = self.object[@"adress"]; _title = [NSString stringWithFormat:@"%@", [_object objectForKey:@"name"]]; [PFGeoPoint geoPointForCurrentLocationInBackground:^(PFGeoPoint *currentLocationGeoPoint, NSError *error) { //Get current Location if (!error) { PFGeoPoint *distanceGeoPoint = [_object objectForKey:@"location"]; double distanceDouble = [currentLocationGeoPoint distanceInKilometersTo:distanceGeoPoint]; //NSLog(@"Distance: %.1f",distanceDouble); _subtitle = [NSString stringWithFormat:@"%@ - Distance: %.1f km", streetName, distanceDouble]; } }]; } @end </code></pre> <p>Can anyone give me a hint how I can show green and red pins based on a boolean?</p> <p>Thanks in advance!</p>
