1）我想创建一个带罢工的文本，所以我使用了 ext 框架，我已经创建了它并保持在 lbal 上，当我在表格单元格中使用它时，当我选择单元格时，标签上的罢工消失了

尝试将删除线直接添加到带有文本 (price1_lbl) 的标签。如果这不起作用，你可能想试试这个库。

更新：

您可以使用以下代码：

CGSize size = [price1_lbl.text sizeWithFont:[UIFont systemFontOfSize:16.0f]];
UILabel *line = [[UILabel alloc] initWithFrame:CGRectMake(0 , label.frame.size.height / 2, size.width, 1)];
line.backgroundColor = [UIColor blackColor];
[price1_lbl addSubview:line];
