ios - 在 UITableView 中滚动时 CustomCell 图像发生变化

Question

问题:滚动表格时API再次调用。
我完成的代码:

- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath {
    ITableViewCell* cell = ( ITableViewCell* )[self.tblNotes dequeueReusableCellWithIdentifier:@"NoteTableCell"];

    cell.tag = indexPath.row;
    if(cell.tag == indexPath.row) {
        cell = [cell initWithNote:[notesArray objectAtIndex:indexPath.row]];
    }
    [cell setNeedsLayout];
    [cell setNeedsDisplay];
    return cell;
}  

我不想在滚动时调用 initWithNote。

提前致谢。

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

   ITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"NoteTableCell"];
    if (cell == nil) {
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"NoteTableCell" owner:self options:nil];
        cell = [topLevelObjects objectAtIndex:0];
    }

    id object = [notesArray objectAtIndex:indexPath.row];
    if ([object isKindOfClass:[NSDictionary class]]) {
        NSDictionary *dict = (NSDictionary *)object;
        [cell.userNameforNotes setText:[NSString stringWithFormat:@"%@",[[dict valueForKey:@"uploadedBy"] uppercaseString]]];
        [cell.noteDescription setText:[NSString stringWithFormat:@"%@",[[dict valueForKey:@"description"] uppercaseString]]];
        [cell.dateForNotes setText:[NSString stringWithFormat:@"%@",[[dict valueForKey:@"uploadedDate"] uppercaseString]]];
        NSString *urlString = [NSString stringWithFormat:@"%@", [dict valueForKey:@"incidentID"]];
        [cell.noteImage sd_setImageWithURL:[NSURL URLWithString:urlString]];
    }
    return cell;
}
