It'll make everything easier if you can make sure that everything after a opening bracket can be removed.

// find the location of the bracket
NSInteger bracketStart = [str rangeOfString:@"("].location;
// get the substring to the opening bracket
NSString *reducedStr = [str substringToIndex:bracketStart];
// remove whitespace at the end of the needed string
reducedStr = [reducedStr stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

and you can remove the newlines from your countrycode like this:

NSString *countryCode = [@"AF\n   \n" stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

NSString* id_str = [NSString stringWithUTF8String: "Afghanistan (\u0627\u0641\u063a\u0627\u0646\u0633\u062a\u0627\u0646)\0"];
id_str = [[id_str componentsSeparatedByString: @"("] objectAtIndex: 0];

NSString* title = @"AS\n   \n";
title = [title stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString: @"\n "]];
