One method would be to split the string at commas and trim whitespace:

NSArray *substrings = [myString componentsSeparatedByString: @","];
NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet];
NSMutableArray *result = [NSMutableArray array];
for ( NSString *str in substrings )
    [result addObject: [str stringByTrimmingCharactersInSet: whitespace]];

Are all of the strings that you want to break apart in this format?

NSArray *myArray = [string componentsSeparatedByString:@","];
NSString * strippedNumbers = [[myArray objectAtIndex:4] stringByReplacingOccurrencesOfRegex:@"[^0-9]" withString:@""];
NSString *myString = [NSString stringWithFormat:@"%@ %@", [myArray objectAtIndex:3], strippedNumbers];
