如何在Swift3的新行中將JSON數組數據打印到UILabel中

Question

我有這樣的JSON響應：

[
    {
        "days": [
            "Sun",
            "Mon",
            "Tue",
            "Wed",
            "Thu"
        ],
        "times": [
            "09:00-12:00",
            "16:00-21:00"
        ]
    },
    {
        "days": [
            "Fri"
        ],
        "times": [
            "17:00-22:00"
        ]
    }
]

現在，我有了一個UILabel，其中將日期和時間的文本設置為下一行。 UILabel文本將如下所示：

周日周二周三

09：00-12：00

16：00-21：00

周五

17:00-22:00

為此，我正在使用代碼：

var allDays = ""
var allTimes = ""
var allDaysTimes = ""
for operating in shop.operatingDays! {
  print(operating.days ?? "")
  print(operating.times ?? "")
  for days in operating.days! {
    print(days)
    allDays.append(days)
   // cell.operationalDays.text = allDays
  }
  for times in operating.times! {
    print(times)
    allTimes.append(times + "\n") 
    allDaysTimes = allDays + "\n" + allTimes
  }
  cell.operationalDays.text = allDaysTimes + "\n"
}

但是我無法將Fri打印到下一行，但是它與Sun，Mon，Tue，Wed，Thu一起顯示在同一行中。

Answer 1

請嘗試這樣：

for operating in shop.operatingDays! {
    print(operating.days ?? "")
    print(operating.times ?? "")
    cell.operationalDays.text =  operating.days!.joined() + operating.times.joined() + "\n"
}

Answer 2

嘗試這個：

var allDays = ""
var allTimes = ""
var allDaysTimes = ""
for operating in shop.operatingDays! {
  print(operating.days ?? "")
  print(operating.times ?? "")
  for days in operating.days! {
    print(days)
    allDays.append(days)
   // cell.operationalDays.text = allDays
  }

  for times in operating.times! {
    print(times)
    allTimes.append(times + "\n") 

  }
  allDaysTimes.append(allDays + "\n" + allTimes)
  allDays = "\n"
  allTimes = ""

}
cell.operationalDays.text = allDaysTimes
