import UIKit
class ViewController: UIViewController {
var seconds = 59
var minute = 0
@IBOutlet weak var label: UILabel!
@IBOutlet weak var sliderOutlet: UISlider!
@IBAction func slider(sender: UISlider) {
seconds = Int(sender.value)
minute = Int(sender.value)
if seconds == 60 {
minute = minute + 1
seconds = 0
}
label.text = String(minute) + " Minute :" + String(seconds) + " Seconds"
}
var dateFormatter = DateComponentsFormatter()
dateFormatter.allowedUnits = ([.minute, .second])
dateFormatter.unitsStyle = .full
label1.text = dateFormatter.string(from: 105)
输出 -
1分钟45秒
从代码中，您猜测这一行是多余的：
minute = Int(sender.value)
consissis删除它
BTW，什么是行之有效的？当前的行为是什么？即将改变您的逻辑为：
@IBAction func slider(sender: UISlider) {
seconds = Int(sender.value)
minute = seconds/60
label.text = String(minute) + " Minute :" + String(seconds-(minute*60)) + " Seconds"
}
try这个
@IBAction func slider(sender: UISlider) {
let currentSec = Int(sender.value)
minute = currentSec/60
seconds = currentSec%60
label.text = String(minute) + " Minute :" + String(seconds) + " Seconds"
}
