我正在尝试以hh:mm:ss格式显示倒计时,但是由于我没有输出Date而是dateComponents,所以不能使用formatter.dateFormat。是否可以格式化dateComponents?

目前,我得到的输出看起来像这样:

时间:5,分钟:12,秒:45

func nextEventCalculator() -> DateComponents {
    let now = Date()
    let calendar = Calendar.current
    let components = DateComponents(calendar: calendar, hour: 12, minute: 15)  // <- 12:15 pm
    let nextEvent = calendar.nextDate(after: now, matching: components, matchingPolicy: .nextTime)!

    let diff = calendar.dateComponents([.hour, .minute, .second], from: now, to: nextEvent)
    dateCountdownLabel.text = "\(diff)"
    return diff
}

最佳答案

使用 DateComponentsFormatter unitsStyle .positional :

let formatter = DateComponentsFormatter()
formatter.unitsStyle = .positional
dateCountdownLabel.text = formatter.string(from: diff)

关于ios - 是否可以将dateComponent设置为hh:mm:ss格式?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/44476224/
