If you read your string like: "logged/name" into an NSString, you can use
- (NSArray *)componentsSeparatedByString:(NSString *)separator
to split it, like:
NSString *list = @"logged/name";
NSArray *listItems = [list componentsSeparatedByString:@"/"];
Would produce an NSArray of two NSStrings:
[ @"logged", @"name" ]

Yes, thats it. But, how can i access this string? The name i mean, is a dynamic string provided by php.
Ben
NSString *name = [listItems lastObject]; or [listItems objectAtIndex:1];
Brad
NSLog(@"There are %d strings - the first is %@ and the last is %@",[listItems count],[listItems objectAtIndex:0],[listItems lastObject]);

@Lucas Veiga: You would do a URL request to whatever server the PHP file was on and use the result string.

You could do that - but if you're doing what I think you're doing - the better way to do it is to spit your data out of your PHP page as XML data, then use NSXMLParser to read and parse the data from PHP. If you only have one string you're dealing with you might not need to - but if you had more data - I'd look into doing it that way...
