Question

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

ex：总计百分之111

如何将这些百分之一秒转换为

（分钟）:(秒）。（百分之一秒）

（最多60）:(最多60）。（最多100个）

ex：00：01.11

我用它来将数组转换为总数百秒：

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)"

Answer 1

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)")

01：02.11
