This library provides an async image downloader with cache support. For convenience, we added categories for UI elements like
MKAnnotationViewadding web image and cache management
pod try SDWebImage
Objective-C: #import <SDWebImage/UIImageView+WebCache.h> ... [imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
Swift: import SDWebImage imageView.sd_setImage(with: URL(string: "http://www.domain.com/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png"))
pod 'SDWebImage/GIF'to your podfile.
UIImageView, it will only show the 1st frame as a static image.
YESto show the entire animated images and
NOto only show the 1st frame. For all the other platforms (tvOS, watchOS) we will fallback to the backwards compatibility feature described above
UITableView determines the size of the image by the first image set for a cell. If your remote images
don't have the same size as your placeholder image, you may experience strange anamorphic scaling issue.
The following article gives a way to workaround this issue:
SDWebImage does very aggressive caching by default. It ignores all kind of caching control header returned by the HTTP server and cache the returned images with no time restriction. It implies your images URLs are static URLs pointing to images that never change. If the pointed image happen to change, some parts of the URL should change accordingly.
If you don't control the image server you're using, you may not be able to change the URL when its content is updated. This is the case for Facebook avatar URLs for instance. In such case, you may use the
SDWebImageRefreshCached flag. This will slightly degrade the performance but will respect the HTTP caching control headers:
[imageView sd_setImageWithURL:[NSURL URLWithString:@"https://graph.facebook.com/olivier.poitrey/picture"] placeholderImage:[UIImage imageNamed:@"avatar-placeholder.png"] options:SDWebImageRefreshCached];
Add these before you call
[imageView sd_setShowActivityIndicatorView:YES]; [imageView sd_setIndicatorStyle:UIActivityIndicatorViewStyleGray];
There are three ways to use SDWebImage in your project:
platform :ios, '7.0' pod 'SDWebImage', '~> 4.0'
If you are using Swift, be sure to add
use_frameworks! and set your target to iOS 8+:
platform :ios, '8.0' use_frameworks!
There are 4 subspecs available now:
WebP (this means you can install only some of the SDWebImage modules. By default, you get just
Core, so if you need
WebP, you need to specify it).
Carthage is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods.
To install with carthage, follow the instruction on Carthage
In the source files where you need to use the library, import the header file:
At this point your workspace should build without error. If you are having problem, post to the Issue and the
