 1 + (instancetype)cellWithTableView:(UITableView *)tableView existedComments:(NSString *)comments
 2 {
 3     TripNoticeLogCell *cell;
 4     if (comments) {
 5         cell = [tableView dequeueReusableCellWithIdentifier:@"twoLineNoticeLog"];
 6         if (cell == nil) {
 7             cell = [[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([DemoCell class]) owner:nil options:nil] objectAtIndex:1];
 8         }
 9     } else {
10         cell = [tableView dequeueReusableCellWithIdentifier:@"oneLineNoticeLog"];
11         if (cell == nil) {
12             cell = [[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([Demo2Cell class]) owner:nil options:nil] objectAtIndex:0];
13         }
14     }
15     return cell;
16 }
