如何解决我正在尝试创建2个pickerview，但是我想第二个picker视图根据第一个选择更改其选项

所以，我正在尝试创建2个选择器视图，第二个选择器视图将具有3个不同的数组选项，第一个选择器视图选项将根据选择的选项确定您将拥有的数组选项。请帮忙！我尝试了许多不同的方法，这是我当前的代码，非常感谢！

导入UIKit

StrikingOptions类：UIViewController {

@IBOutlet weak var Options: UITextField!

@IBOutlet weak var SecondOptions: UITextField!



var firstOptions = ["Offense","Defense","Movement"]
var secondOptions1: [String] = ["Jab","Cross","Uppercut"]
    
    var secondOptions2 = ["Blocking","Parrying","Counters"]
        
        var secondOptions3 = ["Directional Movement","Angles","Head Movement" ]

    


    func configure2(with secondOptions: [String]) {
        self.secondOptions1 = secondOptions
         self.secondOptions2 = secondOptions
         self.secondOptions3 = secondOptions
    }
 
  






var firstOptionsPicker = UIPickerView ()
var secondOptionsPicker = UIPickerView ()




override func viewDidLoad() {
    super.viewDidLoad()
 
    
   

    Options.inputView = firstOptionsPicker
    SecondOptions.inputView = secondOptionsPicker
    
    

    
    Options.placeholder = "Select an Option"
    SecondOptions.placeholder = "Select an Option"
   
    
    
    
    Options.textAlignment = .center
    SecondOptions.textAlignment = .center
   
    
   
    
    
    firstOptionsPicker.delegate = self
    firstOptionsPicker.dataSource = self
secondOptionsPicker.delegate = self
secondOptionsPicker.dataSource = self
  
    
 
    
    firstOptionsPicker.tag = 1
    secondOptionsPicker.tag = 2
