PINCache
Fast, non-deadlocking parallel object cache for iOS and OS X.
[PINCache](Source/PINCache.h) is a fork of TMCache re-architected to fix issues with deadlocking caused by heavy use. It is a key/value store designed for persisting temporary objects that are expensive to reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar stores, one in memory ([PINMemoryCache](Source/PINMemoryCache.h)) and one on disk ([PINDiskCache](Source/PINDiskCache.h)), all backed by GCD and safe to access from multiple threads simultaneously. On iOS, PINMemoryCache
will clear itself when the app receives a memory warning or goes into the background. Objects stored in PINDiskCache
remain until you trim the cache yourself, either manually or by setting a byte or age limit.
PINCache
and PINDiskCache
accept any object conforming to NSCoding. Put things in like this:
Objective-C
UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]];
[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately
Swift
let img = UIImage(data: data, scale:UIScreen.main.scale)
PINCache.shared().setObject(img, forKey: "img")
Get them back out like this:
Objective-C
[[PINCache sharedCache] objectForKeyAsync:@"image" block:^(PINCache *cache, NSString *key, id object) {
UIImage *image = (UIImage *)object;
NSLog(@"image scale: %f", image.scale);
}];
Swift
PINCache.shared().object(forKey: "image") { (cache, key, object) in
if let image = object as? UIImage {
print("image scale: %f", image.scale)
}
}
Both PINMemoryCache
and PINDiskCache
use locks to protect reads and writes. PINCache
coordinates them so that objects added to memory are available immediately to other threads while being written to disk safely in the background. Both caches are public properties of PINCache
, so it's easy to manipulate one or the other separately if necessary.
Collections work too. Thanks to the magic of NSKeyedArchiver
, objects repeated in a collection only occupy the space of one on disk:
Objective-C
NSArray *images = @[ image, image, image ];
[[PINCache sharedCache] setObject:images forKey:@"images"];
NSLog(@"3 for the price of 1: %d", [[[PINCache sharedCache] diskCache] byteCount]);
Swift
// In Swift, Array, String, and Dictionary are all value types.
let images = [image, image, image] as NSArray // Cast to NSArray
PINCache.shared.setObject(images, forKey: "images")
print("3 for the prices of 1: %d", PINCache.shared.diskCache.byteCount)
