This method accepts a string and a dictionary. The string is the original string in which you want to replace various characters, the second one is a dictionary containing the characters you want to replace as the keys and the new characters you want to insert as the values.

- (NSString *)replaceSubstringsIn:(NSString *)string with:(NSDictionary *)replacements {

    NSString *result = string;

    for (NSString *key in replacements) {
        result = [result stringByReplacingOccurrencesOfString:key
                                                   withString:replacements[key]];
    }

    return result;
}

You can call it like this

NSDictionary *dictionary = @{ @" " : @"-", @"some" : @"any"};
NSString *string = @"some to any";

NSLog(@"%@", [self replaceSubstringsIn:string with:dictionary]);

write a dictionary contains the replace characters and write your own function to iterate the character replacement(then wrap it in a NSString category) Or enumerate and replace them.
