A generic NSData cache for storing data to disk, which is backed by NSCache for in-memory data.
Just include the header somewhere up top:
#import "ECDataCache.h"Then use it in your code like so:
NSData *someData = [ECDataCache.sharedCache dataForKey:@"some key"];
if (someData) {
// Do stuff with someData
} else {
// someData doesn't exist
}You can also use it with URLs to store and load images. For example:
NSURL *url = [NSURL URLWithString:@"http://www.educreations.com/static/images/logo/logo-large-dark.png"];
NSData *data = [ECDataCache.sharedCache dataForURL:url];
if (data) {
// We are good to go
UIImage *image = [UIImage imageWithData:data];
} else {
// Fetch the url
...
// On successful fetch, store the image to disk
[ECDataCache.sharedCache setData:data forURL:url];
