FlyImage takes the advantages of SDWebImage, FastImageCache and AFNetworking, is a simple and high performance image library.
Features:
- High Performance, reduce memory operations while rendering, avoid
Memory warningcaused by image - Store and retrieve different size of small images in one memory file, smooth scrolling
- Simple, support
UIImageView,CALayercategory - An asynchronous image downloader
- Support
WebPformat - Support
mmapto improve I/O performace
Set the Podfile like this:
platform :ios, '8.0'
pod 'FlyImage', '~>1.0'
If you are using Swift, be sure to add use_frameworks!:
platform :ios, '8.0'
use_frameworks!
pod 'FlyImage', '~>1.0'
If you want to support WebP, just change the Podfile:
platform :ios, '8.0'
pod 'FlyImage/WebP', '~>1.0'
Using UIImageView and CALayer Category
#import "FlyImage.h"
...
UIImageView *imageView = [[UIImageView alloc] initWithFrame:frame];
[imageView setPlaceHolderImageName:@"default"
thumbnailURL:[NSURL urlWithString:@"http://thumbnail"]
originalURL:[NSURL urlWithString:@"http://original"]];
[]self.view addSubview:imageView];
...
UIImageView *iconView = [[UIImageView alloc] initWithFrame:frame];
[iconView setIconURL:[NSURL urlWithString:@"http://original"]];
[]self.view addSubview:iconView];
...
Using FlyImageCache
// retrieve a specific key, and get callback
[[FlyImageCache sharedInstance] asyncGetImageWithKey:key
completed:^(NSString *key, UIImage *image) {
imageView.image = image;
}];
// remove a image from the cache
[[FlyImageCache sharedInstance] removeImageWithKey:key];
// delete all images
[[FlyImageCache sharedInstance] purge];
Using FlyImageIconCache
// add a new icon with a specific key
[[FlyImageIconCache sharedInstance] addImageWithKey:key
size:drawSize
drawingBlock:^(CGContextRef context, CGRect contextBounds) {
UIImage *image = [UIImage imageWithName:@"imageName"];
UIGraphicsPushContext(context);
[image drawInRect:contextBounds];
UIGraphicsPopContext();
}
completed:nil];
// retrieve a specific key, and get callback
[[FlyImageCache sharedInstance] asyncGetImageWithKey:key
completed:^(NSString *key, UIImage *image) {
imageView.image = image;
}];
