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](https://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Protocols/NSCoding_Protocol/Reference/Reference.html). Put things in like this: - -**Objective-C** -```objective-c -UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]]; -[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately -``` -**Swift** -```swift -let img = UIImage(data: data, scale:UIScreen.main.scale) -PINCache.shared().setObject(img, forKey: "img") -``` - -Get them back out like this: - -**Objective-C** -```objc -[[PINCache sharedCache] objectForKeyAsync:@"image" block:^(PINCache *cache, NSString *key, id object) { - UIImage *image = (UIImage *)object; - NSLog(@"image scale: %f", image.scale); -}]; -``` -**Swift** -```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** -```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** -```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) -``` - -## Installation - -### Manually - -[Download the latest tag](https://github.com/pinterest/PINCache/tags) and drag the `PINCache` folder into your Xcode project. - -Install the docs by double clicking the `.docset` file under `docs/`, or view them online at [cocoadocs.org](http://cocoadocs.org/docsets/PINCache/) - -### Git Submodule - - git submodule add https://github.com/pinterest/PINCache.git - git submodule update --init - -### CocoaPods - -Add [PINCache](http://cocoapods.org/?q=name%3APINCache) to your `Podfile` and run `pod install`. - -### Carthage - -Add the following line to your `Cartfile` and run `carthage update --platform ios`.

It uses the concept of download and processing tasks to ensure that even if multiple calls to download or process an image are made, it only occurs one time (unless an item is no longer in the cache). PINRemoteImageManager is backed by **GCD** and safe to **access** from **multiple threads** simultaneously. It ensures that images are decoded off the main thread so that animation performance isn't affected. None of its exposed methods allow for synchronous access. However, it is optimized to call completions on the calling thread if an item is in its memory cache. - -PINRemoteImage supports downloading many types of files. It, of course, **supports** both **PNGs** and **JPGs**. It also supports decoding **WebP** images if Google's library is available. It even supports **GIFs** and **Animated WebP** via PINAnimatedImageView. - -PINRemoteImage also has two methods to improve the experience of downloading images on slow network connections. The first is support for **progressive JPGs**. This isn't any old support for progressive JPGs though: PINRemoteImage adds an attractive blur to progressive scans before returning them. - -![Progressive JPG with Blur](/progressive.gif "Looks better on device.") - -[PINRemoteImageCategoryManager](Pod/Classes/PINRemoteImageCategoryManager.h) defines a protocol which UIView subclasses can implement and provide easy access to -PINRemoteImageManager's methods. There are **built-in categories** on **UIImageView**, **PINAnimatedImageView** and **UIButton**, and it's very easy to implement a new category. See [UIImageView+PINRemoteImage](/Pod/Classes/Image Categories/UIImageView+PINRemoteImage.h) of the existing categories for reference. - - -### Download an image and set it on an image view: - -**Objective-C** -```objc -UIImageView *imageView = [[UIImageView alloc] init]; -[imageView pin_setImageFromURL:[NSURL URLWithString:@"http://pinterest.com/kitten.jpg"]]; -``` - -**Swift** -```swift -let imageView = UIImageView() -imageView.pin_setImage(from: URL(string: "https://pinterest.com/kitten.jpg")!) -``` - -### Download a progressive jpeg and get attractive blurred updates: - -**Objective-C** -```objc -UIImageView *imageView = [[UIImageView alloc] init]; -[imageView setPin_updateWithProgress:YES]; -[imageView pin_setImageFromURL:[NSURL URLWithString:@"http://pinterest.com/progressiveKitten.jpg"]]; -``` - -**Swift** -```swift -let imageView = UIImageView() -imageView.pin_updateWithProgress = true -imageView.pin_setImage(from: URL(string: "https://pinterest.com/progressiveKitten.jpg")!) -``` - -### Download a WebP file - -**Objective-C** -```objc -UIImageView *imageView = [[UIImageView alloc] init]; -[imageView pin_setImageFromURL:[NSURL URLWithString:@"http://pinterest.com/googleKitten.webp"]]; -``` - -**Swift** -```swift -let imageView = UIImageView() -imageView.pin_setImage(from: URL(string: "https://pinterest.com/googleKitten.webp")!) -``` - -### Download a GIF and display with PINAnimatedImageView - -**Objective-C** -```objc -PINAnimatedImageView *animatedImageView = [[PINAnimatedImageView alloc] init]; -[animatedImageView pin_setImageFromURL:[NSURL URLWithString:@"http://pinterest.com/flyingKitten.gif"]]; -``` - -**Swift** -```swift -let animatedImageView = PINAnimatedImageView() -animatedImageView.pin_setImage(from: URL(string: "http://pinterest.com/flyingKitten.gif")!) -``` - -### Download and process an image - -**Objective-C** -```objc -UIImageView *imageView = [[UIImageView alloc] init]; -[self.imageView pin_setImageFromURL:[NSURL URLWithString:@"https://i.pinimg.com/736x/5b/c6/c5/5bc6c5387ff6f104fd642f2b375efba3.jpg"] processorKey:@"rounded" processor:^UIImage *(PINRemoteImageManagerResult *result, NSUInteger *cost) - { - CGSize targetSize = CGSizeMake(200, 300); - CGRect imageRect = CGRectMake(0, 0, targetSize.width, targetSize.height); - UIGraphicsBeginImageContext(imageRect.size); - UIBezierPath *bezierPath = [UIBezierPath bezierPathWithRoundedRect:imageRect cornerRadius:7.0]; - [bezierPath addClip]; - - CGFloat sizeMultiplier = MAX(targetSize.width / result.image.size.width, targetSize.height / result.image.size.height); - - CGRect drawRect = CGRectMake(0, 0, result.image.size.width * sizeMultiplier, result.image.size.height * sizeMultiplier); - if (CGRectGetMaxX(drawRect) > CGRectGetMaxX(imageRect)) { - drawRect.origin.x -= (CGRectGetMaxX(drawRect) - CGRectGetMaxX(imageRect)) / 2.0; - } - if (CGRectGetMaxY(drawRect) > CGRectGetMaxY(imageRect)) { - drawRect.origin.y -= (CGRectGetMaxY(drawRect) - CGRectGetMaxY(imageRect)) / 2.0; - } - - [result.image drawInRect:drawRect]; - - UIImage *processedImage = UIGraphicsGetImageFromCurrentImageContext(); - UIGraphicsEndImageContext(); - return processedImage; - }]; -``` - -**Swift** -```swift -let imageView = FLAnimatedImageView() -imageView.pin_setImage(from: URL(string: "https://i.pinimg.com/736x/5b/c6/c5/5bc6c5387ff6f104fd642f2b375efba3.jpg")!, processorKey: "rounded") { (result, unsafePointer) -> UIImage?

See our [Installation](http://texturegroup.org/docs/installation.html) guide for instructions. - -## Performance Gains - -Texture's basic unit is the `node`. An ASDisplayNode is an abstraction over `UIView`, which in turn is an abstraction over `CALayer`. Unlike views, which can only be used on the main thread, nodes are thread-safe: you can instantiate and configure entire hierarchies of them in parallel on background threads. - -To keep its user interface smooth and responsive, your app should render at 60 frames per second — the gold standard on iOS. This means the main thread has one-sixtieth of a second to push each frame. That's 16 milliseconds to execute all layout and drawing code! And because of system overhead, your code usually has less than ten milliseconds to run before it causes a frame drop. - -Texture lets you move image decoding, text sizing and rendering, layout, and other expensive UI operations off the main thread, to keep the main thread available to respond to user interaction. - -## Advanced Developer Features - -As the framework has grown, many features have been added that can save developers tons of time by eliminating common boilerplate style structures common in modern iOS apps. If you've ever dealt with cell reuse bugs, tried to performantly preload data for a page or scroll style interface or even just tried to keep your app from dropping too many frames you can benefit from integrating Texture. - -## Learn More - -* Read the our [Getting Started](http://texturegroup.org/docs/getting-started.html) guide -* Get the [sample projects](https://github.com/texturegroup/texture/tree/master/examples) -* Browse the [API reference](http://texturegroup.org/appledocs.html) - -## Getting Help - -We use Slack for real-time debugging, community updates, and general talk about Texture.

Those properties - * will be ignored when rasterizing descendants. - * - * Note: this has nothing to do with -[CALayer shouldRasterize], which doesn't work with ASDisplayNode's asynchronous - * rendering model. - * - * Note: You cannot add subnodes whose layers/views are already loaded to a rasterized node. - * Note: You cannot call this method after the receiver's layer/view is loaded. - */ -- (void)enableSubtreeRasterization; - -@end - -NS_ASSUME_NONNULL_END diff --git a/Example/Pods/Texture/Source/ASDisplayNode+Convenience.h b/Example/Pods/Texture/Source/ASDisplayNode+Convenience.h deleted file mode 100644 index 3c00f672..00000000 --- a/Example/Pods/Texture/Source/ASDisplayNode+Convenience.h +++ /dev/null @@ -1,28 +0,0 @@ -// -// ASDisplayNode+Convenience.h -// Texture -// -// Copyright (c) Facebook, Inc. and its affiliates.
