I have an iPhone app which needs to load some data from a URL.

I have an iPhone app which needs to load some data from a URL. I have the following line of code:

NSString *versionControlContents = [NSString stringWithContentsOfURL:[NSURL URLWithString:versionControlURL] encoding:encoding error:NULL];

The issue that I’m having is that if the contents of the URL have changed since the first time the URL was loaded, the changes aren’t being reflected. Every subsequent time that line of code runs, versionControlContents ends up with the same content as the first time it ran.

I’m assuming this is because the iPhone has some sort of caching mechanism so that it doesn’t actually load the data from the URL every subsequent time. How can I disable this temporarily?

Thanks!

    You might try + requestWithURL:cachePolicy:timeoutInterval:

    Then you can set your cacheing policy as you wish.
