How do I fetch a string from a server?

Question

Let's say I have an html file on my server called sample.txt (it's a plain text document)

Inside the sample.txt file is a line that says http://sample.com

In my app's delegate I have this code

NSDictionary* defaults = @{@"server_addr": @"http://sample.com"}; [[NSUserDefaults standardUserDefaults] registerDefaults:defaults];

Instead of having to change the server_addr within the app when needing to change servers, I'd like to change the server_addr from outside the app by calling whatever line of code is in sample.txt on my server.

How can I do this?

Any help would be greatly appreciated!

You can use NSURLSessionDownloadTask to download file from server.

Or if You want to check version data of server You can get even "Last-Modified" field from HTTP response header, and compare with current data version in your app.

Read the downloaded file to get what data that You want.
