iOS Reading a TXT data file, from HTTP

Fontano · Sep 22, 2008

I have my app working with my REST webservices.
However, the XML overhead is un-believably horrible on EDGE connections, so-so on 3G, and okay on Wi-FI (or when on the simulator).

I have turned my REST service to output a deliminited TXT file instead of a well formed XML. This has resulted in a 92% drop in the file size.

Is there a code sample out there, on what is the best way to read, load, and parse out the deliminted lines. So I can load them into my custom class objects that I am using in the current app.

Probably the simplest way is to load the whole file into a NSString then split the string into lines with componentsSeparatedByCharactersInSet: then split each line into components with the same...

Here is code I used recently to parse out each line in a text file:

Code:

           NSArray *fileData = [[NSString stringWithContentsOfFile:myFile] componentsSeparatedByString:@"\r\n"];
            for (NSString *dataLine in fileData) {
                .....

You could use the same code to parse each line of data - just change @"\r\n" to @",".

If you're going with a simple plain-text format that isn't XML, I'd recommend using JSON. Use this to parse the JSON:

Code:

NSString *urlContents = [NSString stringWithContentsOfURL:
						   [[NSURL alloc] initWithString:
							@"htttp://aaa/a/a.tx"]];

should do the trick.
