Clear NSURLConnection cache

Question

Is there a way to clear NSURLConnection cache?

I used that to download some strings but I keep getting the same strings even though I changed that from my server.

You can clear the cache explicitly using:

obj-c

[[NSURLCache sharedURLCache] removeAllCachedResponses];

swift

 URLCache.shared.removeAllCachedResponses()

You specify cache policy when you create your NSURLRequest object. Set the cachePolicy property to NSURLRequestReloadIgnoringCacheData or use the initWithURL:cachePolicy:timeoutInterval: initializer. See documentation on cache policy.

What does this have to do with the question? – Iulian Onofrei Jul 23 '15 at 09:54
Clearly this is a better way to use (or not use) a cache than removing all cached responses, so this has a lot to do with the question don't you think? – sridhar_rajagopal Feb 19 '21 at 02:13

I had same issue, no matter what I do I will keep getting old data from web. I did a simple solution. I made a php script. This script reads the data . now I access this php script instead of the data file and I am good to go.
