The following link used for loading data:
http://pastebin.com/raw/wgkJgazE
Above download link is configurable and can be set in PinsViewModel as urlstring parameter.
Images link, Likes, time of creation and JSON is cached in-memory only for all Pin items.
The classes in model are structured as follows:-
Cache size can be configured using class CacheConfiguration parameter maxItems
**** Cache default duration can be set using duration in same class CacheConfiguration
Downloading Libraries are structured as follows
`DownloadManager`-->`CacheManager`
The items are removed from cache based on number of times the object was requested and in case of same number of requests most recent item is kept while others are removed
Pull to refresh has been avoided as data is presented with initial page photos being shown on top
**** An image load may be cancelled using method cancelDownload defined in class Downloader
In case of a pin/url being requested by multiple sources simultaneously (even before it has loaded) the number of times the pin was requested is incremented by 1 and this place a crucical role in deciding which item to remove from cached
Clean build the Pinboard Manager Workspace in case SwiftyJSON is not found. For the following project I make use of SwiftyJSON as a dependancy for Decoding JSON object and assigning members in model classes.
Build the Workspace with target selected as PinBoardFramework to get the framework generated as output in same directory.
Add SwiftyJSON and PinBoardManager.framework generated to you linked framework and Libraries along with Embeded binaries and import the frameworks in your source to make use of library. (add framework in target you are building)
import PinBoardManager
import SwiftyJSON
