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，您可能需要给予 this lib尝试一下。

更新:

您可以使用此代码:

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];
