Xcode: split a NSString into NSArray

NSString *str = @"011597464952,01521545545,454545474,454545444|Hello this is were the message is.";

NSArray *firstSplit = [str componentsSeparatedByString:@"|"];
NSAssert(firstSplit.count == 2, @"Oops! Parsed string had more than one |, no message or no numbers.");
NSString *msg = [firstSplit lastObject];
NSArray *numbers = [[firstSplit objectAtIndex:0] componentsSepratedByString:@","];

// print out the numbers (as strings)
for(NSString *currentNumberString in number) {
NSLog(@"Number: %@", currentNumberString);
}
