If you just want to trim certain characters from a string, you can use NSCharacterSet and stringByTrimmingCharactersInSet: method of NSString.

NSCharacterSet *chs = [NSCharacterSet characterSetWithCharactersInString:@"<>"];
string = [string stringByTrimmingCharactersInSet:chs];

There are lots of way to achieve this:

One you can use the way bigkm shows. Second Empty Stack had suggest a better way too.

Here is one other way:

NSString *dataToken = @"<8c09362c 82d6b735 c82fb2d9 8070db6f f73419b3 9da15e34 72aba570 6fbf5a45>";
NSString *str = [dataToken stringByReplacingOccurrencesOfString:@"<" withString:@""];
str = [str stringByReplacingOccurrencesOfString:@">" withString:@""];

simple

NSString *dataToken = @"<8c09362c 82d6b735 c82fb2d9 8070db6f f73419b3 9da15e34 72aba570 6fbf5a45>";
NSString *token = [dataToken substringWithRange:NSMakeRange(1, [dataToken length]-2)];
