I just started using SKMap library on IOS recently.
One behavior of the function didSelectAnnotation (from the SKMapViewDelegate Protocol), is that whenever an annotation got selected, the center of the map's visible region will move to the location of that annotation.
Is there any way that I can disable this?
It's actually not a feature of didSelectAnnotationfunction, but rather of showCalloutForAnnotation function. Just set parameter animated in the function to NO.

I have just build an swift app that takes data+coords from dynamoDB and puts it onto the ios mapkit. There are two sets of coords: one for current user location and one from dynamoDB. I want these coords to be able to update inside the map, but do not want the actual mapView to zoom and move at all (only the user can zoom and move).
I have achieved everything above except the last part. Currently whenever the annotations are added and mapView.showAnnotations is called, the mapView zooms and moves to enclose the annotations. How do I disable this?
To show mapView annotations without updating mapView zoom and constraints, use addAnnotations() rather than showAnnotations.
I am guessing that you used code from online (which we all do, no worries) and that your code looked something like this. If I am right, then you likely have a line somewhere like this:
[map setRegion:scaledRegion animated:YES];
That line is the issue. You need to use some sort of boolean to make it so that it only happens once. So you could set the boolean has_mapped = false until you have called your update method once, at which point it = true. Then change your line to say something like,
if (has_mapped)
[map setRegion:scaledRegion animated:YES];
using target 8.0 MapKit, I would like to define an MKAnnotation (such as a pin, or a custom one) that remains fixed on the center of the map view as the user moves the map around. Once the user stops moving the map, I would like to be able to read the new coordinates of the annotation. How can I do this? This in swift, thank you soo much
You can follow this link to accomplish this task.They are doing something very similar to your requirement. Its quite descriptive. Link
In one of my application I need to move marker on drag and drop, once user drop the pin I need to get the dropped pin location.
This is very basic feature of map but I am surprised that there is no such option in the library.
In native map there is property called "Draggable", is there any equivalent property in the Arcgis ?
With the help of ARCGIS community support, I was able to find the answer for this question.
We have to implement the method mapView:didMoveTapAndHoldAtPoint:mapPoint:features: on AGSMapViewTouchDelegate.
The delegate method gets called every time the user moves his finger while taping and holding the map view. The method also provides the array of features at that location. So in the method you can update the geometry of the features to the new mapPoint.
You can use this sample as a reference. The sample adds a marker if you tap and hold and changes the location of that marker when you move while taping and holding.
I'm making an iOS app (using Swift) that has a map in the Mapbox iOS SDK. I've gotten to the point of displaying several markers on the map. Now, I want the user to be able to select a marker from the list, panning to that marker (easy), which also makes the marker's callout bubble appear automatically without the user having to touch it (not so easy).
It's this last task I'm having trouble with. While I've found the RMMarker class's showLabel() method, I can't seem to directly access a RMAnnotation's associated RMMarker object, so I'm not sure where or how to call this method.
Does anyone know how this is done?
Ignore the showLabel() API — this is not the callout in use, but rather a text label that's possible directly on the annotation.
You probably want -[RMMapView selectAnnotation:animated:] with a NO in the animated argument.
I'm designing an app using Swift for a food truck. I want to use MapKit to show a pin on the live location of the truck so one can look at the app to see it moving in realtime. I was able to get the server-side element set up using PHP/MySQL. Currently, the app makes a HTTP request every 3 seconds.
How should I go about animating the moving pin (or other image)? I tried a few methods already (if you have others, please suggest!):
I removed the pin and quickly added a new one in my HTTP function. While this works, I would prefer a smooth animation, not a flashing, jerky pin.
I subclassed MKMapViewDelgate like with a didAddAnnotationViews delegate that animates the pin's frame using UIView.animateWithDuration as suggested here. Animation only occurred when the map was initially loaded. Also, I have no idea how this would work with coordinates, since it involves frames.
I subclassed MKAnnotation with a modifiable var coordinate. In my HTTP function, I changed the coordinate. EDIT: This now works since I properly refreshed the mapView (thanks #Paulw11). However, I still have two main issues:
There's no linear animation, which I desire to better simulate real-time movement. How would I go about animating the pin's coordinates? Should I use UIView, like in method 2, a fast NSTimer, or something else?
Due to using the setCenterCoordinate function to forcibly refresh the map, the map cancels any current touches. How do I detect if there's any touches on the MapView so I can prevent the forced update?
