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 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.
Good afternoon,
I would like to know if I can take a picture and then draw something in the image (with the finger movement, for example, a black line "handwritted"). Is it possible?
If that's possible... How can I start doing that?
Edit:
I want to take a picture from my iPhone (that's what I currently have in my App) and then I would like to draw something in that picture.
Thanks in advance.
There is no one tutorial to this. And as #Stephen mentioned in the comments, it is not a 2 min job. However, you can start with the following tutorials.
http://w3z.in/7ef - How To Make A Simple Drawing App with UIKit.
http://w3z.in/9b1 - Apple's official UIKit guide.
http://w3z.in/e2c - iOS 7 graphics tutorial.
The key here would be to have patience, do some small experiment apps and then figure out what to do in your app.
Thanks
I want to develop an Angry Birds style game (more for learning purpose), so I am digging into Cocos2D + Box2D and after having done a few test all by code I am wondering which tool can I use to design level easier ?
A bit of google pointed me out Tiled or R.U.B.E. but I am not really sure if it's what I need. Tiled seem to be more designed for tiled game like a plat-former and I don't really know about R.U.B.E.
What I'd like to do is being able to place my body manually in a scene, set their physic property and so...
Which tool would you recommend for this kind of level design ?
Thank in advance.
I advise you to download/buy LevelHelper/SpriteHelper, they have helped me a lot when I was a novice with box2d. I think it's just what you need, once you learn the basics then you can go forward freely without them. In addition now there's also one or more tutorials on the Ray Wenderlich site that will help you even more like this (The softwares are not free, but in my opinion they worth their price)
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've just cloned the three.js project from github. I'm interested in creating a circle on a 2d plane that I can drag with my mouse. I have no experience in graphics programming (WebGL or OpenGL).
Can someone please point me in the right direction? I've tried google, but the examples seem too complicated.
Many thanks in advance,
I think this is something you need to have a go at. It's not nearly as complicated as you might think. If the maths are scaring you off, don't worry three.js handles it all for you, you just need to add a camera, some shapes and ask it to render them.
Please do take the time to go through aerotwists three js tutorials as these will give you a good grounding in how to setup a basic scene.
You will quickly realise that once you have a scene you can change objects quite easily using your current scene.
As for dragging things around, I'm sure that will come just try to walk before you can run.
