Question

有关我做错的任何建议吗？初始化对象时，我似乎无法将另一个类中的数组作为参数。这是我的具体情况：

我正在尝试创建一个锻炼应用程序。该应用程序包含几种不同的锻炼。每次锻炼都有自己独特的训练阵容。

我有WorkoutObj的代码（这个结构创建了一个锻炼，需要一个NSArray workoutDrillSet）

import UIKit

struct WorkoutObj {

var workoutType: NSString
var workoutNumber: Int
var workoutDesc: NSString
var workoutDuration: Int
var workoutDrillSet: NSArray

init(type: String, number: Int, duration: Int, desc: String, drillSet: NSArray)
{
    workoutType = type
    workoutNumber = number
    workoutDuration = duration
    workoutDesc = desc
    workoutDrillSet = drillSet
}

}

以下是我的DrillObjects（此结构是钻取数组所包含的对象 - 换句话说，钻取数组将由DrillObject1，DrillObject2，DrillObject3等组成）

import UIKit

struct DrillObject {

var drillDesc: NSString
var drillDurationMin: Int
var drillDurationSec: Int
var drillHRZone: Int
var drillEffort: Int
var drillCadence: Int

init(M: Int, S: Int, hRZone: Int, effort: Int, cadence: Int, name: NSString)
{
    drillDesc = name
    drillDurationMin = M
    drillDurationSec = S
    drillHRZone = hRZone
    drillEffort = effort
    drillCadence = cadence
}

}

我的下一堂课是我的EDrills课程。此类将每个DrillObject放入一个数组中。创建的数组名为arrayE1Drills

import UIKit

class EDrills: NSObject {

let dE1: DrillObject
let dE2: DrillObject
let dE3: DrillObject
let dE4: DrillObject
let dE5: DrillObject
let dE6: DrillObject
let dE7: DrillObject
let dE8: DrillObject
let dE9: DrillObject
let dE10: DrillObject
let dE11: DrillObject
let dE12: DrillObject
let dE13: DrillObject
let dE14: DrillObject

var arrayE1Drills : [DrillObject]


override init()
{
    dE1 = DrillObject ( M: 5, S: 0,  hRZone: 2, effort: 8, cadence: 95, name: "W/U Pedal Easy @ 90 RPM")

    dE2 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Stand")
    dE3 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Sit")

    dE4 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Stand")
    dE5 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Sit")

    dE6 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Stand")
    dE7 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Sit")

    dE8 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Stand")
    dE9 = DrillObject ( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Sit")

    dE10 = DrillObject( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Stand")
    dE11 = DrillObject( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Sit")

    dE12 = DrillObject( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Seated 80% left leg")
    dE13 = DrillObject( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Seated 80% right leg")

    dE14 = DrillObject( M: 0, S: 30, hRZone: 2, effort: 10, cadence: 95, name: "W/U Seated 80% left leg")


    arrayE1Drills =
    [dE1,
    dE2,
    dE3,
    dE4,
    dE5,
    dE6,
    dE7,
    dE8,
    dE9,
    dE10,
    dE11,
    dE12,
    dE13,
    dE14]


}

}

最后，我有了ECEouts类。这是一个举行多次训练的课程。 e1 workoutObject需要保存EDrills类的arrayE1Drills。

import UIKit


class EWorkouts {

var e1: WorkoutObj
var e2: WorkoutObj
var e3: WorkoutObj
var e4: WorkoutObj
var e5: WorkoutObj

var arrayEAll : [WorkoutObj]
var arrayE0to45 : [WorkoutObj]
var arrayE30to45: [WorkoutObj]
var arrayE45to60: [WorkoutObj]
var arrayEGreater45: [WorkoutObj]
var arrayE0to60: [WorkoutObj]
var arrayEGreater60: [WorkoutObj]

var myEDrillsClass : EDrills


 init()
{
    myEDrillsClass = EDrills()
    let myArray = myEDrillsClass.arrayE1Drills


    e1 = WorkoutObj(type: "E", number: 1, duration: 63, desc: "Rolling Hilly Course", drillSet: myArray)

 }

当试图将arrayE1Drills加载到锻炼中时，我收到错误：Cannot invoke initializer for type "WorkoutObjc" with an argument list of type (type: String, number: Int, duration: Int, desc: String, drillSet: [DrillObject])

Answer 1

存在类型不匹配

var workoutType: NSString - ＆gt; init : String

var workoutDesc: NSString - ＆gt; init : String

以及之后NSArray＆lt; - ＆gt; Array

从Swift 1.2开始，Foundation基本类型不会隐式地转换为Swift对应的

我建议只使用Swift类型

无法为类型调用初始化程序：使用类型的参数列表：
