I am pretty new to the iOS world, and since I am a geographer by trade I of course wanted to play with some of the Mapkit functions.
I downloaded the KMLViewer sample, and as part of that sample the KML file has points and polygons. For the points users can press one of the points and get a call out with the attributes of that point. This functionally is not built in for the polygons. I would like to be able to press one of the polygons and have a call out open with its attributes?
Can someone help guide me on how to accomplish this? Thank you so much for any help, guidance, and patients.
Thanks,
Paul
It's all about Overlay view. Use MKAnnotationView class to set properties and annotate as much as you like. It's a view so you can build it like any view and put it on the map. You will also find other sample codes here. Also found nice example on OverlayView here.

I'm trying to define pixels of an image based on their color code, and display them on command. I've been researching this and can't seem to find information on the subject, I've mostly been pointed towards "Animations" and "Core Image Filters" which isn't quite what I'm looking for. Any information on the subject is much appreciated.

try this sample code of a color picker. one of the views is a plane of continuous colors and is probably what you want. apple has good source code and the swift book is great for avoiding bad questions. you have to watch it as a beginer.too many simple questions on this site and they will block you from asking more.
I want to use ground overlays using MKMapView . Is it possible to do so.
Please give me a solution.
Thanks.
Its a little late, but I think i found your answer. As a public service to others with the same question, but where the "Ray Wenderlich link to 6 Flags Magic Mountain MapKit Tutorial: Overlay Views" doesn't quite cut the mustard:
Try This Link: https://www.raywenderlich.com/158175/advanced-mapkit-tutorial-custom-tiles You'll need to be proficient at Graphic Line Art / illustration or trade deals with an Arts student because it involves preparing your own graphics for the actual tiles used, this is right down your alley.
I'm trying to create a map of the office I'm working at. I have a high resolution image, and would like to autorotate it in the direction the user is heading, allowing the user to navigate around the map. I thought this could be accomplished using CoreMotion/CoreLocation and a UIScrollView, but this seems like there's some work involved.
So I'm wondering if there are easier solutions for combining a custom map and direction/position on that map - can MapKit handle this for me? Are there other frameworks that can help me show a local 2D map with compass orientation on it?
You can convert your high-res image into map tiles easily with TileMill.
You should use some custom tiles with MKTileOverlay which only display at a very high zoom level (like z 18 or whatever). I suggest you take a look over at NSHipster and read what they have about it:

*Disclaimer: I haven't tried this myself, came across the NSHipster article while searching for solutions to my own problems.
I have gone through Vuforia's sample code for user Defined Target. I really dont find any clues on modifying the sample code to render some text instead of rendering the 3D model(the teapot). Can anyone help me understand how to change the sample code to render a text?
You should start by reading this vuforia "knowledge database" article, which explains how to replace the teapot with a textured plane.
Once you've done that, the simplest way to display text will be to generate a texture containing this text, and display it on the plane. This other article explains how to use other textures than the 2 that are provided with the sample app.
Hope this helps!
I am looking for a good and fast way to wrap locations that are in a specific range on a MKMapView in a single marker. Clicking on that marker brings you closer to the center point of this locations. You can see what I mean on the picture below.
mc donalds app - map sample screen
My first thought was to check a specific pixel range for each marker, hide the ones that are closer than X pixels to each other and get the center of them to create a new marker.
Did anyone of you ever did something similar?
There's a demo from WDC 11 or 10 that does exactly that, and coalesces based on proximity, not grid. Much better looking than DTCluster.
After a while of searching an testing, I found several frameworks for this like:
REVClusterMap, SuperPin, DTClusterMaker and a lot more. At the moment I stick with "REMarkerClusterer". It's pretty simple to implement and is free (MIT License)

Here is a nice article about clustering:

If someone else has good frameworks for this in his bookmarks/github-list, please post it here. I sill would like to see them ...
