我正在尝试获取一个对象的时间戳与未来30天之间的日期数组。

I'm trying to get an array of dates between the time stamp of one of my objects and 30 days into the future.

我使用了下面的代码，但是我没有得到想要的结果，并且在尝试创建标题中描述的方法时遇到了麻烦。任何帮助都会很棒，谢谢。

I've used the code below but i'm not getting the desired result and am having trouble trying to make a method described in the title. Any help would be great, thank you.

var dates = [Date]() func fetchDays() { let cal = Calendar.current var dateComponents = DateComponents() dateComponents.year = 2017 dateComponents.month = 2 dateComponents.day = 12 guard let startDate = cal.date(from: dateComponents) else { return } var start = cal.startOfDay(for: startDate) for _ in 0 ... 30 { guard let daysBetween = cal.date(byAdding: .day, value: 1, to: startDate) else { return } start = daysBetween dates.append(start) } }

推荐答案

您将1加上相同的开始日期，因此您的数组将一遍又一遍地填充相同的日期。只需将 1 替换为循环索引+ 1。

You are adding 1 to the same start date so your array is filled with the same date over and over. Simply replace 1 with the loop index + 1.

for i in 0 ... 30 { if let newDate = cal.date(byAdding: .day, value: i + 1, to: startDate) { dates.append(newDate) } }

您不需要开始变量。
