Question 1

How to preload web content with EVURLCache in iOS?

Accepted Answer

Place files in the /PreCache folder with the same directory structure as the URLs. For example, for evict.nl/index.html, store it in /PreCache/evict.nl/index.html. Then enable EVURLCache in AppDelegate by calling EVURLCache.activate().

Question 2

EVURLCache vs Apple's URLCache: which is better for offline apps?

Accepted Answer

EVURLCache offers advanced features like pre-caching, configurable size limits, and case-insensitive handling, making it superior for robust offline functionality. Apple's URLCache is more basic and integrated, suitable for simple caching without extra setup.

Question 3

Does EVURLCache work with Alamofire in Swift?

Accepted Answer

Yes, EVURLCache is fully compatible with Alamofire and other NSURLRequest-based libraries. It automatically caches responses, so no additional code is needed beyond activating the cache in your app delegate.

Question 4

How to clear the cache in EVURLCache?

Accepted Answer

EVURLCache doesn't provide a built-in method to clear cache; you need to manually delete files from the cache directory. The storage path can be obtained using EVURLCache.storagePathForRequest(theRequest) for specific files.

Question 5

What is the maximum file size limit in EVURLCache?

Accepted Answer

By default, it's 16MB (2^24 bits), but you can configure it by setting EVURLCache.MAX_FILE_SIZE. Ensure EVURLCache.MAX_CACHE_SIZE is at least 16 times larger, or the file size limit won't be effective.

Question 6

Can EVURLCache handle case-sensitive URLs?

Accepted Answer

Yes, by default it converts paths to lowercase for compatibility with case-insensitive web servers. You can disable this by setting EVURLCache.FORCE_LOWERCASE = false if you need case-sensitive matching on file systems.
