嘗試直接添加刪除線與文本（price1_lbl）的標籤。如果這不起作用，你可以試試this lib。

UPDATE：

您可以使用此代碼：

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];
