does anybody know how it is possible to add an accessibility label to a map annotation? I've tried adding it to the MKAnnotationView and the MKAnnotation but neither works. VoiceOver always only reads "pin" when an annotation is selected, while the original Maps application features the correct title when selecting an annotation.
Thanks and best regards,
Chris
In your -mapView:viewForAnnotation: set the accessibilityValue of your returned MKAnnotationView object.

I'm struggling to identify how I can tell that the MKMapView is showing the current user location pin in a UI Test. This is a MKUserLocation annotation (and I've created an MKAnnotationView to use an image for the pin instead of the blue spot.)
Debugging tells me that the MKUserLocation annotation instance has a title of "My Location". I was expecting that the following would work:
app.maps.element.otherElements["My Location"]
would return it but [that code].exists returns false. Printing debugDescription of otherElements lists a whole set of annotations on the map but not the User Location.
Is there a different type of XCUIElement that represents the pin/annotation/annotation view that I can check for?
Use accessibility labels to access your MKAnnotationView. In your code, retrieve your user location annotation and set an accessibility label for it:
yourAnnotation.accessibilityLabel = "labelYouWillUseToFindIt"
Then during your tests you can do:
app.maps.element.otherElements["labelYouWillUseToFindIt"]
Use print(app.debugDescription) to see if your annotation is visible and if not, force it to be accessible with:
yourAnnotation.isAccessibilityElement = true

I am using iOS 9 with Swift 2.
I have been unable to find a way of displaying text on hover of a pin that exists on a map using mapkit.
I would like to do this without having to have a callout, which forces the user to click on the pin.
Any ideas?
There isn't really a "hover" per say like with a web app. There is either tap (selected) or no tap (unselected), but terminology aside, you're going to want to use an MKAnnotationView. Specifically I'd replace it with a UILabel using this method:
func viewForAnnotation(_ annotation: MKAnnotation) -> MKAnnotationView?
That will let you set the view to be whatever you want, so create the UILabel view, then set it to be your annotation view there
Set MKAnnotarion.title property, then you can see the value on TAP. As mentioned above comment, there is no Hover concept in iOS
I am using map on my IOS application. I can see the annotation on my map, and when I tap on that there is the description, which I have set. My question is whether I can have this description visible when map first loads and not make the user tap on the annotation to view it?
is that possible?
Thanks.
use an overlay instead of an annotation
So `MKAnnotation's. Fun stuff.
My questions:
What's the difference between an annotation's title and its subtitle and how does that affect the visual component of the annotation?
What's the difference between a MKPinAnnotationView and a MKAnnotationView?
Are there different types of map annotations in iOS apart from pins?
Title is main heading of your pin.
The subtitle is actually displaying the address/(common info) of the dropped pin.You can store other deeply information of related to title that is puted on pin.
MKAnnotation is a protocol you need to adopt if you wish to show your object on a MKMapView. The coordinate property tells MKMapView where to place it. title and subtitle properties are optional but if you wish to show a callout view you are expected to implement title at a minimum.
MKAnnotationView visually presents the MKAnnotation on the MKMapView. The image property can be set to determine what to show for the annotation. However you can subclass it and implement drawRect: yourself.
MKPinAnnotationView is a subclass of MKAnnotationView that uses a Pin graphic as the image property. You can set the pin color and drop animation.
Don't forget about the leftCalloutAccessoryView and the rightCalloutAccessoryView properties of MKAnnotationView that can be used to customize the callout view.
The title and subtitle are displayed when a pin is selected on the map. The subtitle simply falls below the title.
MKPinAnnotationView is simply an specialized form of MKAnnotationView that knows how to draw a pin (and a shadow) and also allows setting the pin color. It's the only built-in annotation view with an image, you have to make your own if you want something different (but it's very easy to do).
I am developing a small project, which will display the source and distance trace route, I did complete till that, now the thing is I am unable to add two annotation pin of different color for source and destination, suppose I am using red for source and green for destination.
This might be huge help for everybody who are learning and working.
Thanks
You could use images for your pins or you could use a subclass of MKAnnotationView - MKPinAnnotationView and just change the pinColor property, it's documentation can be found here:
