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.

Answer 1

You can clear the cache explicitly using:

obj-c

[[NSURLCache sharedURLCache] removeAllCachedResponses];

swift

 URLCache.shared.removeAllCachedResponses()

Answer 2

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.

Answer 3

Add one random number at the end of file name

Like abc.pdf?rand=10023

Answer 4

Here's a way from official Apple pages that might help. Just read the short and informative answer in the link.

TLS Session Cache

Answer 5

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.
