Read .txt file from the Internet - Objective-C

Question

In my iPhone application, how can I download a .txt file from the Internet and then get its contents in NSString. For example, let's say the text file was at http://www.somewebsite.com/textfile.txt

Then I want to do the following:

if(user has internet connection) NSString *textFile = download text file from http://www.somewebsite.com/textfile.txt else NSLog(@"user has no internet"); 

Can someone show me the code for this?
