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)

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.
