问题描述
我对显示特定日期有疑问。在这种情况下,我会从我的API(06/16/2015)中获得一个随机日期,该日期总是会变化。我将其放入具有日期类型的变量名称 toDate
中。对于我的 fromDate
变量,我需要在 toDate
前30天。我阅读了此但仍然无法正常工作。

variable. I read this but its still not working. Thanks in Advance.
*注意:我在此控制器中没有任何DatePicker
*Note : I dont have any DatePicker in this controller
推荐答案
在这里:
let toDate = `your date object`
let fromDate = Calendar.current.date(byAdding: .month, value: -1, to: toDate)
or,
// If you want to have exactly 30 days before
let fromDate = Calendar.current.date(byAdding: .day, value: -30, to: toDate)
