Question

这是我的JSON数据

{
    "service_facility_id": 1,
    "service_id": 4,
    "facility_name": "Fitting",
    "charge_per_min": 40,
    "charge_per_km": 50
},
{
    "service_facility_id": 10,
    "service_id": 4,
    "facility_name": "Health Care",
    "charge_per_min": 100,
    "charge_per_km": 0
}

目前我正在使用Get方法在X Code中打印特定的JSON输出。所以我设法分钟（charge_per_min）值。但我希望以HH（小时）格式显示标签，因此如何将其转换为分钟到小时格式并显示为uilabel .. 代码如下。

if let con = country["charge_per_km"] as? Int {              
      print("+++++\(con) +++ ")
      self.chargPerKm.append(con)

      print(self.chargPerKm)

      let encodedArray : NSData = NSKeyedArchiver.archivedData(withRootObject:self.chargPerKm) as NSData
      //Saving
      let defaults = UserDefaults.standard
      defaults.setValue(encodedArray, forKey:"charge_per_km")
      print("\(UserDefaults.standard.value(forKey: "charge_per_km")!)")
      defaults.synchronize()
      print(defaults)                   
}

任何人帮助我。

在游乐场试试

func minutesToHoursMinutes (minutes : Int) -> (hours : Int , leftMinutes : Int) {
    return (minutes / 60, (minutes % 60))
}

let tuple = minutesToHoursMinutes(minutes: 100)

tuple.hours  /// 1
tuple.leftMinutes /// 40

如何在swift3中将min转换为小时？
