Ios 更复杂的数组字典

我试图计算一个人在一天中喝一杯水的次数（以一小时为间隔），我不知道如何正确构建此数据结构，预期数据如下所示：

day1 = [hour interval: [time, time, time], hour interval: [time], hour interval: [time], hour:[time]]

它打印一个空数组…到目前为止，我有：

var counts = [String:Array<NSDate>]()
var dict = [[NSDate:Array<[String:Array<NSDate>]>]]()

//datesArray -> is an array of dates from something like monday to friday
/*
datesArray:

2016-07-23
2016-07-24
2016-07-25
2016-07-26
2016-07-27
2016-07-28
2016-07-29
2016-07-30
*/


    for date in datesArray {

           //tempDoses has the times when the user took the glass of water 
/*
tempDoses:

2016-07-28 23:50:50 +0000
2016-07-26 13:06:57 +0000

*/


              for temp in tempDoses {

                    if calendar.isDate(date, inSameDayAsDate: temp.logTime)



                        let dateformatter = NSDateFormatter()

                        dateformatter.dateFormat = "HH:mm"

                        let myDate = dateformatter.stringFromDate(temp.logTime)



                        let h = self.getHour(myDate)

                        for m in counts {
                         var o = m

                            if o.0 == h {
                                o.1.append(temp.logTime)
                            }
                        }
                    }
                }

                if counts.count > 0 {
                    dict.append([date:[counts]])
                    counts.removeAll()
                }else{
                    dict.append([date:[]])

您的预期输出与您的输入不匹配！例如，在

2016-07-22

上：

// Input
2016-07-22 09:10:59 +0000
2016-07-22 09:10:26 +0000
2016-07-22 09:09:28 +0000

// My expected output
2016-07-22 = [9: ["09:10", "09:09"]]

// Your expected output:
2016-07-22 = ["10": [09:10, 09:13]]

玩下面的代码，直到你得到你想要的在处理

NSDate

时，请特别注意时区，因为它是错误的主要来源：

let timeZone = NSTimeZone(forSecondsFromGMT: 0)

let calendar = NSCalendar.currentCalendar()
calendar.timeZone = timeZone

let formatter = NSDateFormatter()
formatter.dateFormat = "HH:mm"
formatter.timeZone = timeZone

var dict = [NSDate : [Int: [String]]]()

for date in datesArray {
    let dailyDoses = doses
                        .filter { calendar.startOfDayForDate($0.logTime) == date }
                        .sort { $0.logTime.timeIntervalSince1970 < $1.logTime.timeIntervalSince1970 }

    dict[date] = [Int: [String]]()

    dailyDoses.forEach {
        let hour = calendar.component(.Hour, fromDate: $0.logTime)
        let str = formatter.stringFromDate($0.logTime)

        if dict[date]![hour] == nil {
            dict[date]![hour] = [String]()
        }
        if !(dict[date]![hour]!.contains { $0 == str }) {
            dict[date]![hour]!.append(str)
        }
    }
}

// Print the result
for date in datesArray {
    print(date, "=", dict[date]!)
}

/* Output:

为了省去弄清楚你的源代码是什么样的麻烦，你能编辑你的问题以包含预期的输入和输出吗？好的，很抱歉造成混淆我也做了一些评论，我仍然看不到你的输入是什么。您的

日期的价值是多少？回答得很好，感谢日期格式上的警告：）
