如何在我们的项目中使用指令框架

Question

我是 swift 的新手。我正在尝试在我的代码中使用Instructions framework。我已经成功地用这个函数实现了单个按钮“view_schedule”

@IBOutlet weak var view_schedule: UIButton!

@IBOutlet weak var use_now: UIButton!

func coachMarksController(_ coachMarksController: CoachMarksController, coachMarkAt index: Int) -> CoachMark {
    return coachMarksController.helper.makeCoachMark(for: view_schedule )
   

}

我如何为同一类中的多个按钮实现，即，ApplianceDetailVC.swift 用于我的下一个按钮“use_now”

我为此实现的逻辑是

var firstInstructionFlag = true
var secondInstructionFlag = false

func coachMarksController(_ coachMarksController: CoachMarksController, coachMarkAt index: Int) -> CoachMark {
    //var poi = UIView()
    if firstInstructionFlag == true
    {
        firstInstructionFlag = false
        secondInstructionFlag = true
        
        return coachMarksController.helper.makeCoachMark(for: view_schedule )
    }
    else if secondInstructionFlag == true
    {
        firstInstructionFlag = false
        secondInstructionFlag = false
        
        return coachMarksController.helper.makeCoachMark(for: use_now )
    }
    return coachMarksController.helper.makeCoachMark(for: use_now )
    
}

这个问题是我错误地处理了返回类型，为“use_now”重复它。你能通过提供更好的逻辑来处理这种返回类型吗

func coachMarksController(_ coachMarksController: CoachMarksController, coachMarkAt index: Int) -> CoachMark {
    var poi=UIView()
    if firstInstructionFlag == true
    {
        firstInstructionFlag = false
        secondInstructionFlag = true
        poi = view_schedule
        
    }
    else if secondInstructionFlag == true
    {
        firstInstructionFlag = false
        secondInstructionFlag = false
        poi = use_now
    }
    return coachMarksController.helper.makeCoachMark(for:poi )
    
}
