Features

  • Add an option to scale down large images #787 00bf467 efad1e5 8d1a0ae. Fixed #538, #880 and #586. This one is a more robust solution than #884 or #894. Can be activated via SDWebImageScaleDownLargeImages or SDWebImageDownloaderScaleDownLargeImages

Fixes

  • Fixed #1668 CGContextDrawImage: invalid context 0x0 - b366d84

4.0.0 beta - New platforms (Mac OS X and watchOS) + refactoring, on Oct 5th, 2016

See all tickets marked for the 4.0.0 release

Infrastructure:

  • support for watchOS and OS X platforms #1595
  • the SDWebImage xcodeproj contains the following targets:
    • SDWebImage iOS static (iOS static lib)
    • SDWebImage watchOS static (watchOS static lib)
    • SDWebImage OSX (OSX dynamic framework)
    • SDWebImage iOS (iOS dynamic framework)
    • SDWebImage tvOS (tvOS dynamic framework)
    • SDWebImage watchOS (watchOS dynamic framework)
    • the SDWebImage Demo xcodeproj contains the following targets:
      • SDWebImage OSX Demo
      • SDWebImage iOS Demo
      • SDWebImage TV Demo
      • SDWebImage Watch Demo
  • bumped libwep version to 0.5.1
  • improved unit testing code coverage (35% -> 77%) and integrated CodeCov

Backwards incompatible changes

  • removed all deprecated methods (that we carried around for backwards compatibility in previous versions) #774
  • Renamed SDWebImageManager downloadImageWithURL:options:progress:completed: to loadImageWithURL:options:progress:completed: as it makes more sense, since we check the cache first and download only if needed a32a177
  • Deleted targets: SDWebImage+MKAnnotation, SDWebImage+WebP, SDWebImageFramework:
    • SDWebImage target that build as a static library (all subspecs included) -> libSDWebImage.a
    • SDWebImageiOS and SDWebImagetvOS targets that build as dynamic frameworks
  • Renamed the dynamic frameworks targets from WebImage to SDWebImage. Renamed the WebImage.h to SDWebImage.h to match the framework naming
  • Renamed the schemes for consistency. Updated the Tests Podfile + project.
  • For #883 Fix multiple requests for same image and then canceling one, several breaking changes were needed:
    • SDWebImageDownloader method - downloadImageWithURL:options:progress:completed: now returns a SDWebImageDownloadToken * instead of id <SDWebImageOperation> (give the ability to cancel downloads using the returned token)
    • SDWebImageDownloaderOperation initializer - initWithRequest:options:progress:completed:cancelled split into - initWithRequest:options and addHandlersForProgress:completed:. Note: there is no more cancel block
  • Modern Objective-C syntax done in 64382b9 includes:
    • initializers now return instancetype instead of id
    • explicit designated initializers (i.e. for SDImageCache)
  • For #1575 GIF support using FLAnimatedImage, several changes were needed:
    • replaced type SDWebImageQueryCompletedBlock with SDCacheQueryCompletedBlock and added an NSData * param
    • because of the change above, the done param of SDImageCache queryDiskCacheForKey:done: is now a SDCacheQueryCompletedBlock and those blocks must now include an NSData * param
    • replaced type SDWebImageCompletionWithFinishedBlock with SDInternalCompletionBlock and added an NSData * param
    • because of the change above, the completed param of SDWebImageManager loadImageWithURL:options:progress:completed: is now SDInternalCompletionBlock and those blocks must now include an NSData * param
    • for consistency with the previous change, also renamed SDWebImageCompletionBlock to SDExternalCompletionBlock
    • UIImage will no longer respond to sd_animatedGIFNamed: or sd_animatedImageByScalingAndCroppingToSize:
  • Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581
    • breaks compatibility at least for Swift users of the framework
  • watchOS and OS X support #1595 required
    • renamed SDWebImage iOS static lib target to SDWebImage iOS static for clarity
  • improving the unit tests code coverage #1681 required
    • Refactored NSData ImageContentType category, instead of returning the contentType as a string, the new added method sd_imageFormatForImageData will return a SDImageFormat enum value
    • SDImageCache configuration properties moved into SDImageCacheConfig (which is now available via config property):
      • shouldDecompressImages
      • shouldDisableiCloud
      • shouldCacheImagesInMemory
      • maxCacheAge
      • maxCacheSize
    • The storeImage: methods from SDImageCache were async already, but declared as sync. Properly marked them as async + added completion. Got rid of the recalculate param. If the NSData is provided, use it. Otherwise, recalculate from the UIImage
    • Removed the synchronous methods diskImageExistsForURL: and cachedImageExistsForURL: from SDWebImageManager
    • Removed the synchronous method diskImageExistsWithKey: from SDImageCache
    • Get rid of the confusion caused by cleanDisk and clearDisk on SDImageCache. Renamed cleanDisk to deleteOldFiles. No longer expose the sync clearDisk and deleteOldFiles, just the async ones.
    • Renamed SDImageCache queryDiskCacheForKey:done: to queryCacheOperationForKey:done:
    • Another SDImageCache clarification: imageFromDiskCacheForKey: used to also check the memory cache which I think is misleading. Now imageFromDiskCacheForKey only checks the disk cache and the new method imageFromCacheForKey checks both caches
    • Got rid of removeImageForKey: and removeImageForKey:fromDisk: from SDImageCache that looked sync but were async. Left only the 2 async ones
    • Removed UIImageView sd_cancelCurrentHighlightedImageLoad
  • Added sd_ prefix to the activity indicator related methods (setShowActivityIndicatorView:, setIndicatorStyle:, showActivityIndicatorView, addActivityIndicator, removeActivityIndicator) #1640
  • Use dispatch_main_async_safe for all the completion blocks on the main queue (used to be dispatch_sync) - avoiding locks.
  • Removed dispatch_main_sync_safe as it can be mistakenly used
  • Add url as param to progress block SDWebImageDownloaderProgressBlock - #984

Features:

  • Switched our GIF support to a better implementation: FLAnimatedImage by Flipboard #1575
    • requires iOS 8+ (it's the only way due to FLAnimatedImage requirements)
    • the implementation relies on a WebCache category on top of FLAnimatedImageView
    • details in the README
  • Converted any remaining code to Modern Objective-C syntax - 64382b9
  • Xcode 7 Objective-C updates (Lightweight Generics and Nullability) #1581
  • via #1595 Clarified and simplified the usage of TARGET_OS_* macros. Added SD_MAC, SD_UIKIT, SD_IOS, SD_TV, SD_WATCH. The biggest issue here was TARGET_OS_MAC was 1 for all platforms and we couldn't rely on it.
  • Replaces #1398 Allow to customise cache and image downloader instances used with SDWebImageManager - added a new initializer (initWithCache:downloader:) 9112170
  • UIImage responds to sd_imageData and sd_imageDataAsFormat: via the MultiFormat category. Those methods transform a UIImage to the NSData representation 82d1f2e
  • Created SDWebImageDownloaderOperationInterface to describe the behavior of a downloader operation. Any custom operation must conform to this protocol df3b6a5
  • Refactored all the duplicate code from our WebCache categories into a UIView WebCache category. All the other categories will make calls to this one. Customization of setting the image is done via the setImageBlock and the operationKey e1840c3
  • Due to the change above, the activity indicator can now be added to UIButton, MKAnnotationView, UIImageView
  • Animated WebP support #1438
  • The shared objects (not really singletons) should allow subclassing, therefore the return type of the shared resource method should be instancetype and not a fixed type - c57cf7e
  • Allow to specify NSURLSessionConfiguration for SDWebImageDownloader #1654
  • Add url as param to progress block SDWebImageDownloaderProgressBlock - #984

Fixes:

  • Fix multiple requests for same image and then canceling one #883 + 8a78586
  • Fixed #1444 and the master build thanks to @kenmaz
  • Fixed an issue with the SDWebImageDownloaderOperation : cancelInternal was not called because of the old mechanism rellying on the thread property - probably because that thread did not have a runloop. Removed that and now cancelInternal is called as expected f4bdae6
  • Replaced #781 on replacing dispatch_sync with dispatch_async for the main queue 062e50a f7e8246 c77adf4 fdb8b2c 265ace4 0c47bc3. Check for main queue instead of main thread.
  • Fixed #1619 iOS 10 crash (setObjectForKey: object cannot be nil) - #1676 7940577
  • Fixed #1326 #1424 (Carthage bitcode issue) - #1593
  • Fixed #1639 via #1657 (Add support for downloading images behind redirect)
  • Replaced #1537 via 9cd6779 - fixed a potential retain cycle
  • Updated dispatch_main_async_safe macro in order to avoid redefinition when included as Pod
  • Fixed #1089 by updating the docs on the calling queue for the progressBlock (background queue)
  • Fixed a compilation issue on FLAnimatedImageView+WebCache - #1687

3.8.2 Patch release for 3.8.0 on Sep 5th, 2016

Fixes:

  • Fixed #1608 #1623 #1644 Crash in [NSURLCache cachedResponseForRequest:] - the fix is actually avoiding to access NSURLCache which appears to generate a race condition. We only call it if necesarry (SDWebImageRefreshCached is used and the image cannot be cached by the system when it's too big or behind authentication)

3.8.1 Patch release for 3.8.0 on Jun 7th, 2016

Fixes:

  • SDWebImage 3.8.0 get wrong image #1589 - the issue was caused by the changes in 3.8.0 (Removed the URL query params from the filename (key) fb0cdb6d 1bf62d4 #1584 - fixes #1433 #1553 #1583 #1585) - Reverted.
  • Note: The solution for those issues (i.e. #1433 #1553) is to set the SDWebImageManager cacheKeyFilter block and do their own calculations there.
