UITableView局部刷新

只刷新cell不刷新section，这问题还难住了一阵子

需要用到：

- (void)insertRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation;
- (void)deleteRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation;

注意：(NSArray *)indexPaths里面的下标要不同的哦，要是往最后插入，要记得看仔细哦

    //加载新数据
    self.dataSource = [[NSMutableArray alloc]initWithArray:@[@"",@"",@"",@"",@""]];
    NSArray *array2 = [[NSArray alloc]initWithArray:self.dataSource];
    NSMutableArray *array3 = [[NSMutableArray alloc]init];
    for (int i = 0; i < array2.count; i ++) {

    }
    array2 = [[NSArray alloc]init];
    [tableview insertRowsAtIndexPaths:array3 withRowAnimation:UITableViewRowAnimationRight];
    [tableview endUpdates];
}


@end

 数据从3个变成5个了还带动画效果～～～～～～～
