Asia/Tokyo I want to get only "Tokyo" by removing "Asia/" I know it will get to work by searching for the position of "/" but how do i do that? pls help

To get the location of a substring in a string :
[@"Asia/Tokyo" rangeOfString:@"/"].location

Note this will find the first instance of the substring. You can use
rangeOfString:options:range if you want to find other instances, or search backwards, or other things covered by the options.You can use this as well:
NSString *mainString = @"Asia/Tokyo"; NSUInteger location = [mainString rangeOfString:@"/"].location + 1; NSLog(@"Trimed string:%@",[mainString substringFromIndex:location]); Result: Trimed string:Tokyo

Just split the string with componentsSeparatedByString:@"/" This'll return an array, and you just grab the second element.

That's overkill when you simply need the index of a character.
rob mayoff
Unless this is performance-critical code,
[input componentsSeparatedByString:@"/"][1] is a perfectly good solution.rmaddy
@robmayoff Yes, it works but the thought of scanning the entire string for the delimiter, creating a temporary array full of strings I don't actually need, just to get the index of a character, makes me shiver.

@rmaddy Although the question was how to get the index, the OP isn't actually trying to get the position of the character, he's trying to get the substring delimited by the character.
rmaddy
@David Then use
substringFromIndex: to get the needed substring after getting the range of the delimiter. |
You can use rangeOfString to give you the location of string. I would also run the range through an if statement looking for NSNotFound just in case the string you are looking for isn't found.
