Swift 将秒转换为时间戳

我正在使用Swift计算一个时间数组，以百分之一秒为单位计算平均次数。得到的平均值是总百分之一秒的输出

例：总百分之一秒111

我怎样才能把这一百秒转换成

分：秒。第一百秒

最大60：最大60。最多100

ex:00:01.11

我使用此函数将数组转换为总百分之一秒：

let timeToSecondsArray = valueLast20.map{
     i -> Int in
     let timeString = (i as AnyObject).components(separatedBy: ":")
     let minute = Int(timeString[0])
     let second = Int(timeString[1])
     let hundredthseconds = Int(timeString[2])
     let minuteToSec = minute! * 3600
     let secondToSec = second! * 60
     let totalSeconds = minuteToSec + secondToSec + hundredthseconds!
     return totalSeconds
}

let seconds: Int = timeToSecondsArray.reduce(0, {x, y in x + y})/timeToSecondsArray.count
let one = String(format: "%02ld", seconds/3600)
let two = String(format: "%02ld", (seconds%3600)/60)
let three = String(format: "%02ld", ((seconds%3600)%60))
self.averageTime.text = "\(one):\(two).\(three)"

01:02.11

你的问题是什么？不管怎么说->毫秒111秒不是1分11秒。好吧，让我们重新开始：它实际上不是毫秒，而是百分之一秒。你做错了的是假设111秒的输入是秒，不是，那是111百分之一秒，意味着一整秒和11多百分之一秒。@WillMays这不是苹果秒表计时的方式。Apple秒表格式为00:00.00，注意小数点，表示分、秒和百分之一秒，而不是毫秒。克里斯告诉你的是正确的，111秒是1分51秒。@luk2302啊，好的，我现在明白了，我已经更新了问题

let valueLast20 = ["01:03:24", "01:00:98"]

let hundredthSecondsArray = valueLast20.map{
    i -> Int in
    let timeString = (i as AnyObject).components(separatedBy: ":")
    let minute = Int(timeString[0])
    let second = Int(timeString[1])
    let hundredthSeconds = Int(timeString[2])!
    let minuteToHundredth = minute! * 60 * 100
    let secondToHundredth = second! * 100
    let totalSeconds = minuteToHundredth + secondToHundredth + hundredthSeconds
    return totalSeconds
}

let hundredth: Int = hundredthSecondsArray.reduce(0, +) / hundredthSecondsArray.count
let one = String(format: "%02ld", hundredth / 100 / 60)
let two = String(format: "%02ld", (hundredth / 100 % 60))
let three = String(format: "%02ld", (hundredth % 100))
print("\(one):\(two).\(three)")
