Question

I am trying to populate a table with sections and rows based off array slices. I keep getting " Cannot invoke initializer for type "Objects" with and argument list of type'(sectionName: String, sectionObjects: ArraySlice). Wondering if anyone could shed some light on what I am Missing. Thanks.

您可以使用Array(ArraySlice)

将ArraySlice对象强制转换为Array对象

这是您更新的代码：

func test(){
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = " eee, MMM dd, yyyy "
        let today = (NSDate())
        let comps : NSCalendarUnit = NSCalendarUnit.Day
        let cal = NSCalendar.currentCalendar()
        let todaysDate = cal.startOfDayForDate(today)

        var dates = [String]()
        var displayMe = [String]()

        for i in 0 ... 179 {
            let day = dateFormatter.stringFromDate(cal.dateByAddingUnit(comps, value: +i, toDate: todaysDate, options: [] )!)
            dates += [day]
        }

        for (index, value) in dates.enumerate() {
            let testMe = ("Day  \(index + 1)   - \( value)")
            print(testMe)
            displayMe += [testMe]
        }



        let datesOneRange = displayMe[0...13]
        let datesFifteenRange = displayMe[14...28]
        let datesThrityRange = displayMe[29...58]
        let datesSixtyRange = displayMe[59...88]
        let datesNinetyRange = displayMe[89...99]
        let datesOneHunEighty = displayMe[100...179]




        let dateDict = [ " 5 Days" : datesOneRange,
            " 14 Days" : datesFifteenRange,
            " 30 Days" : datesThrityRange,
            " 60 Days" : datesSixtyRange,
            " 90 Days" : datesNinetyRange,
            "180 Days" : datesOneHunEighty]

        struct Objects {
            var sectionName : String!
            var sectionObjects : [String]!
        }

        var objectArray = [Objects]()

        for (key, value) in dateDict {
            print("\(key) -> \(value)")
            objectArray.append(Objects(sectionName: key, sectionObjects:Array(value)))
        }
    }
