Magic Map

A super simple, easy-to-use, beautiful world map for iOS.

Features

• Simply parse a CLLocationCoordinate2D object (latitude and longitude) to position the marker on the map.
• Changes in marker position are animated by default.
• Easily fix the map to the marker. The map will first animate to the marker location (if animation is enabled), then respond to touch events by bouncing but not moving.
• Built for both standard definition and retina screens.

Implementation

1. Be sure to link the CoreLocation framework to your target in Xcode.
2. Copy the following files into your project:
   • UIMagicMap.h
   • UIMagicMap.m
   • magicMap.jpg
   • magicMap@2x.jpg
   • mapMarker.png
   • mapMarker@2x.png
3. There are two ways to use the magic map.
   • The easy way is to drop a UIView into your storyboard/NIB, give it a custom class of UIMagicMap, then link it to an outlet in your ViewController's header file. If you are implementing it this way be sure to add the UIMagicMap class files in the "Compile Sources" of your target's build phases. You will probably also want to call the setLocation method on the UIMagicMap as soon your view loads. Note that the first setLocation is never animated.
   • To insert the UIMagicMap component programatically, just allocate the object then initialize it with (id)initWithFrame:(CGRect)frame location:(CLLocationCoordinate2D)location fixed:(BOOL)fixed animated:(BOOL)animated.
4. To position a marker on the map (and scroll to/show the location): call the setLocation method.
5. To turn animations off: call the setAnimated method.
6. To fix the map to the marker: call the setFixed method. Note that if the map is currently not positioned over the marker then it will animate/move the map accordingly.
7. To position the map over the marker: call the centerOnMarker method.

Credits

• For the map I used the colors and textures from this world map & pin by Thom van der Weerd. I then added Antarctica to the map and made adjustments to ensure its geographical accuracy, reflecting the mercator projection rather than the equirectangluar projection.
• I used this great blog post to help calculate the target map marker point from latitude and longitude coordinates.
