Answer 1

您需要实现这些方法以使其可见

  - (NSAttributedString *)collectionView:(JSQMessagesCollectionView *)collectionView attributedTextForCellBottomLabelAtIndexPath:(NSIndexPath *)indexPath {
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MMM-yyyy"];//22-Nov-2012
NSString *formattedDateString = [dateFormatter stringFromDate:[[DataArray objectAtIndex:indexPath.row] date]];
        return [[NSAttributedString alloc] initWithString:formattedDateString];
     }

    - (CGFloat)collectionView:(JSQMessagesCollectionView *)collectionView
                       layout:(JSQMessagesCollectionViewFlowLayout *)collectionViewLayout heightForCellBottomLabelAtIndexPath:(NSIndexPath *)indexPath {
        return kJSQMessagesCollectionViewCellLabelHeightDefault;
    }
