iOS - 异步缓存和加载图像 [英] iOS - Caching and loading images asynchronously

问题描述

我想要一个适用于 iOS 的图像加载和缓存库

I want an image loading and caching library for iOS that

• 异步加载图像，
• 缓存图像，具有可配置的缓存大小和 LRU 行为，
• 使用 HTTP HEAD 检查图像是否已更新，
• 在出现错误代码或无效图像时不缓存任何内容.

我看过HJCache，但它只满足这些标准中的前两个.还有更好的吗?

I've looked at HJCache, but it only satisfies the first two of these criteria. Is there something better?

推荐答案

我知道这个帖子已经有人回答了，但是我尝试了一个非常有效的库.之前用的是ASIHttpRequest，差别很大.

I know that this thread has been answered, but I have tried a library that has worked great. I was using ASIHttpRequest before and the difference is big.

https://github.com/rs/SDWebImage

此外，如果有人需要调整或裁剪远程图像，并且具有与 SDWebImage 提供的相同功能，我将 SDWebImage 库与 UIImage+Resize 库(由 Trevor Harmon)集成，并创建了一个示例项目.我修改了 SDWebImage 的代码来处理转换(裁剪、调整大小).

Also, if someone needs to Resize or Crop the remote images, and have the same features that SDWebImage provide, I have integrated SDWebImage library with UIImage+Resize library (by Trevor Harmon), and created an example project. I modified the code of SDWebImage to deal with transformations (crop, resize).

该项目已在 https://github.com/toptierlabs/ImageCacheResize 上公开.随意使用它！

The project is public on https://github.com/toptierlabs/ImageCacheResize. Feel free to use it!
