How to parse an xcode url and get data that returns i.e

bilal

engineer

to different xcode fields i.e

NSString *id=1
NSString *name=bilal
NSString *designation=engineer

note. my url is self constructed to simply return the fields

result = [NSString stringWithFormat: "dev.evsoft.pk/fgglobal/…; it's something like that man — Bilal

I don't know if you are already establishing a connection to your web service or not… if not look up NSURLConnection in Google or Stack Overflow.

Regarding the only part of your question that I understood:

NSString* result = @"1\nbilal\nengineer";
NSArray* components = [result componentsSeparatedByString:@"\n"];

NSString* id = [components objectAtIndex:0];
NSString* name = [components objectAtIndex:1];
NSString* designation = [components objectAtIndex:2];

id is not a keyword in Objective-C. It’s a type name and, since types are in a different name space than the name space for variables, id is also a valid variable name.

Oops you're right, I removed that bit of misinformation from my answer.

yes i know that about id.. i was just explaining my requiremnt

@Bavarious, that's not quite true. Yes, id is a type, but according to this page it's also a reserved word. That makes sense because id has some special behavior. It's a built-in type that can be used in place of any object pointer type, and when you use it you're basically saying "I don't care about the type."
