MLImageCache has been written as an alternative to clumsy SDWebCache. It is based on NSOperation / NSOperationQueue combo, which gives it additional features and safety.
The highlights:
- Two .m files and .h files. Just drag to your project and go. You can also use CocoaPods.
- Asynchronous download and disk read gives it an unmatched speed. It does not interfere with scrolling.
- Uses ARC and is carefully engineered not to induce strong reference cycles. It's memory reliability is thoroughly tested.
- It downloads only one copy of an image no matter how many times has it been requested.
- If multiple downloads are initiated with the same image view, only the last one is processed (important for reusable cells in table views)
- It can download arbitrary data, not only images.
- It supports prioritization and simultaneous downloads based on NSOperationQueue priority system.
Use CocoaPods or copy those 4 files directly into the project.
#import "UIImageView+Cache.h"
...
[self.imageView mll_setImageWithURL: self.urlToImage ];
or simply
[self.imageView setImageWithURL: self.urlToImage ];
if it does not collide with other libs.
And that's it! You can replace SDImageCache instantly. For more advanced features see MLImageCache.h
