I have been working with NSArrays and NSMutableArrays that store NSDate objects for a few days now. I noticed that calling [listOfDates removeObject:date1] removes all the NSDate objects from the array. I have instead been doing this to remove objects:

  NSMutableArray *dateList; // Has Dates in it
  NSDate *dateToRemove;     // Date Object to Remove
  __block NSUInteger indexToRemove;
  __block BOOL       foundMatch = NO;
  [dateList enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    if ([obj isEqualToDate:dateToRemove]) {
      indexToRemove = idx;
      foundMatch = YES;
      *stop = YES;
     }
  }];
  if (foundMatch) {
    [dateList removeObjectAtIndex:indexToRemove];
  }

Is there a better way to be doing this? Perhaps another data structure? Or a simpler function?
