MapKit (MKMapView): zPosition does not work anymore on iOS11

问题 On iOS11 the zPosition stopped working for the annotationView.layer. Every time the map region changes. No luck with original solution: layer.zPosition = X; No luck with bringViewToFront / SendViewToBack methods Xcode 8.3/9 UPDATE (SOLUTION thanks Elias Aalto): When creating MKAnnotationView: annotationView.layer.zPosition = 50; if (IS_OS_11_OR_LATER) { annotationView.layer.name = @"50"; [annotationView.layer addObserver:MeLikeSingleton forKeyPath:@"zPosition" options:0 context:NULL]; } In

Hello i have stuck in one situation on map where i have managed to show custom annotation. When the annotation is tapped i have to show a view with some information and one button. when user taps on the button then one alert should display. code is as follows - (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { if (![view.annotation isKindOfClass:[MKUserLocation class]]) { POCustomAnnotation *annotation = (POCustomAnnotation *)[view annotation]; UIView *bgview=[[UIView alloc]initWithFrame:CGRectMake(-30, -150,130, 150)]; bgview.backgroundColor=[UIColor

问题 I need to show on my MkMapView about 10 locations (and respective annotations) and after pressing a button I need to add new different annotations according to different JSON parsing results (for example a locationIDValue < 100 means a red pin, otherwise green). This is the simplified code: - (void)viewDidLoad { [super viewDidLoad]; map.showsUserLocation = true; map.mapType = MKMapTypeStandard; arrayID = [[NSMutableArray alloc] initWithObjects: @"id1", @"id2", @"id3", @"id4", @"id5", @"id6",

change UIImage from MKAnnotation in the MKMapView

问题 I have a mapView with only on MKAnnotation, that has a costume image. When the user changes the mapType, I need to change the image of that annotation. The way I did that was to remove the annotation from the map, and insert another with the correct image, bu i don't think is the best way. It takes about 1 ou 2 seconds to show the new image. How can I do it without remove the annotation and drop another? Thanks, RL 回答1: You can use the viewForAnnotation: instance method of the map view (not

Animate removal of annotations

问题 I have a map and a set of annotations, each with a 'parent' property. Currently when I add annotations I implement the didAddAnnotationViews method to animate those annotations so they appear to come from their parent's coordinate. Is there a way of doing this during the removal of annotations? When I remove an annotation from the map I want it to animate in to its parent coordinate, and as far as I know there is no equivalent for didAddAnnotationViews for when an annotation is removed. 回答1:

问题 I have a data set of annotations that can update very quickly. At the moment I remove all annotations before replotting them back onto the map. NSArray *existingpoints = [mapView.annotations filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"!(self isKindOfClass: %@)", [MKUserLocation class]]]; [mapView removeAnnotations:existingpoints]; I calculate where they are anyway within the custom object so would like to be able to call this and "move" the annotation without removing and

问题 I have a working loop to setup annotations for the title and subtitle elements for some working data points. What I want to do within that same loop structure is to set the pin color to Purple instead of the default. What I can't figure out is what I need to do to tap into my theMapView to set the pin accordingly. My working loop and some attempts at something... .... for var index = 0; index < MySupplierData.count; ++index { // Establish an Annotation myAnnotation = MKPointAnnotation(); ...

Draw a circle of 1000m radius around users location in MKMapView

由 自作多情 提交于 2019-11-27 02:51:16
(Using iOS 5 and Xcode 4.2) I have an MKMapView and want to draw a circle of 1000m radius around the user location. On the surface it would seem that implementing the mapView:viewForAnnotation: map view delegate method, and adding a custom MKAnnotationView for the users location, would be a perfect solution. It would look something like this: - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation { // If it's the user location, return my custom MKAnnotationView. if ([annotation isKindOfClass:[MKUserLocation class]]) { return myCustomAnnotationView; }

MKAnnotationView and tap detection

问题 I have a MKMapView . I added a UITapGestureRecognizer with a single tap. I now want to add a MKAnnotationView to the map. I can tap the annotation and mapView:mapView didSelectAnnotationView:view fires (which is where I'll add additional logic to display a UIView). The issue is now when I tap the annotation, the MKMapView tap gesture also fires. Can I set it so if I tap the annotation, it only responds? 回答1: There might be a better and cleaner solution but one way to do the trick is
