TouristHelper

Libraries Used:

• GoogleMaps: For showing map

• KVOController: KVO helper.

Optimal Path Algorithm:

This is actually a TSP problem. But since we are talking about more than 100 nodes than the basic TSP is going to be impractical. Hence, a simple greedy approach is taken (which sometimes may give a result far from best optimal but it serves the purpose for this demo.) The implementation is isolated in such a way that it can be easily replaced with better one (like one of the variants of TSP).

Setup:

Cocoapods needs to be installed first. Then after cloning, from the project directory run

pod install

Running:

• make sure the bundle identifier is com.mush.Tourist. It's because that this bundle identifier is being used for Google Map Service.

TODO:

• more unittest.
• caching layer for Services.
• allow user to filter POI types. now the list contains only 'food','bar' and 'museum'.
• create more animation for UIs
• make visually more aesthetic.
