问题 I've got a problem with my MKAnnotationView s when MKUserTrackingModeFollowWithHeading is enabled on the MKMapView. I positioned my images using the centerOffset property of the MKAnnotationView. Specifying the coordinates of the pin's tip relative to the coordinate system at the center of the image is somewhat counter-intutive, but I came up with the following formula: annotationView.centerOffset = CGPointMake(imageWidth/2.0 - tipXCoordinate, imageHeight/2.0 - tipYCordinate); This works fine

问题 I've been trying to use a UILongPressGestureRecognizer in a MKAnnotationView subclass. Interestingly the gesture recognizer only triggers when using two ore fingers/touches. What prevents the gesture recognizer to get triggered with only one touch? Implementation UILongPressGestureRecognizer *pressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)]; pressRecognizer.minimumPressDuration = 0.25; pressRecognizer.numberOfTapsRequired = 0;

问题 I have integrated FBAnnotationClustering on mkmapview which works perfectly, but when there is more than one annotation at exactly the same place I cannot display the annotationView with the correct informations. I'm trying to loop through the annotations and display them in the same view (each with a callout button to display more info). So far I managed to make one callout work to display the details at the bottom, but in the annotationView it displays it without the right title, and there

问题 Since iOS 11, when I use setImage in my custom MKAnnotationView , the image is displayed with an animation. The problem is when I select and deselect the MKAnnotationView and the image has a different size. It results in a weird animation. No problem until iOS 11, can we stop this behaviour? 回答1: Seeing that this is the only mention of this issue (feature?) that I've found anywhere over the past year and a half, let me first thank you for being my only source of sanity. With that, I've

问题 MKPinAnnotationView does not allow you to use a custom image as 'pin' and enable dragging at the same time, because the image will change back to the default pin as soon as you start dragging. Therefore I use an MKAnnotationView instead of an MKPinAnnotationView. While using MKAnnotationView instead of MKPinAnnotationView does keep your custom image shown as your 'pin' it doesn't support the drag & drop animation that you get with the default pin. Anyway, my issue is that after I drag my

问题 I have a map to which I add several annotations, like so: for (Users *user in mapUsers){ double userlat = [user.llat doubleValue]; double userLong = [user.llong doubleValue]; CLLocationCoordinate2D userCoord = {.latitude = userlat, .longitude = userLong}; MapAnnotationViewController *addAnnotation = [[MapAnnotationViewController alloc] initWithCoordinate:userCoord]; NSString *userName = user.username; NSString *relationship = user.relationship; [addAnnotation setTitle:userName];

问题 I'm trying to hide a pin on a MapKit view, and while setting the hidden property to YES works, I can still tap on it and get didSelectAnnotationView messages!. Naturally, I tried setting userInteractionEnabled to NO , but I'm still receiving the messages. This is what I've tried. a is my annotation view. a.hidden = YES; a.layer.hidden = YES; a.userInteractionEnabled = NO; There's something that I'm missing here, and I've Googled everywhere and can't find anything that works. Any clues? 回答1:

问题 I'm on iOS 7 and I have the following problem. I can't find a clue after some research curiously... I have a map view annotation with left and right accessories but transparent in the middle (default iOS 7 behavior I think). How to change the default translucent/transparent background to any other color I want? 回答1: Is your MKMapView inside a UITableViewCell ? I had a similar issue, where the UITableViewCellSelectionStyle of the cell caused this visual glitch. Setting it to

问题 I want to customise the iOS8 MapView Callout bubble which get visualised when clicking on a MKAnnotationView. The Default bubble is a bit limiting (having only Title,Subtitle and 2 accessory view) so I'm struggling to find an alternative solution. Here two possible ways and the relative problems I'm facing: PROBLEM 1) CREATING A CUSTOM CALLOUT BUBBLE Digging the Apple documentation I have found this: When you use a custom view instead of a standard callout, you need to do extra work to make
