Answer 1

当我动态添加一行时，我使用 insertRowsAtIndexPaths：这是一个示例函数

- (void) allServersFound {
    // called from delegate when bonjourservices has listings of machines:
    bonjourMachines = [bonjourService foundServers]; // NSArray of machine names;

    NSMutableArray *tempArray = [[NSMutableArray alloc] init];

    int i = 0;
    for (NSArray *count in bonjourMachines) {
        [tempArray addObject:[NSIndexPath indexPathForRow:i++ inSection:0]];
    }

    [[self tableView] beginUpdates];
    [[self tableView] insertRowsAtIndexPaths:(NSArray *)tempArray withRowAnimation:UITableViewRowAnimationNone];
    [[self tableView] endUpdates];

    [tempArray release];
}

如果您要从数组中填充表格，则只需向数组中添加一个元素并调用[myTable reloadData]

重新加载数据既好又简单，但据我所知并没有动画......

ReloadData 可以在 teble 视图中添加行，但是如果您想要在添加行时添加一些动画，那么您应该使用这些代码行。

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
        NSMutableArray *tempArray = [[NSMutableArray alloc] init];
        [tempArray addObject:[NSIndexPath indexPathForRow:indexPath.row+1 inSection:0]];

        [mainArray insertObject:@"new row" atIndex:indexPath.row+1];

        [[self tableView] beginUpdates];
        [[self tableView] insertRowsAtIndexPaths:(NSArray *)tempArray withRowAnimation:UITableViewRowAnimationFade];
        [[self tableView] endUpdates];

}
