Protocol method not getting called in UIView-CodePudding

I have 2 UIViews 1st: ToolbarView: This is the code for protocol in 1st view:

public enum ToolBarActionType: String {
  case style = "style"
  case undo = "undo"
  case redo = "redo"
}

public protocol ToolBarDelegate: AnyObject {
  func toolBarButtonAction(actionType: ToolBarActionType)
}

@objc public class ToolbarView: UIView {
 enum ToolbarItems: Int {
     case style = 1
    case undo = 2
    case redo = 3
  }

 public weak var delegate: ToolBarDelegate?

//This method is called onClick of toolbar buttons
@objc func toolBarButtonAction(sender: UIButton) {
    let style = ToolbarItems(rawValue: sender.tag)
      switch style {
      case .style :
        delegate?.toolBarButtonAction(actionType: .insertionStyle)
      case .undo :
        delegate?.toolBarButtonAction(actionType: .undo)
      case .redo :
        delegate?.toolBarButtonAction(actionType: .redo)
      default :
        return
      }
    }
}

This is my 2nd view: TextView This is the code in textview:

import Toolbar

 public class TextView: UIView, ToolBarDelegate {
 private var toolbar = Toolbar()

 public init() {
 toolbar.delegate = self
}

//this method is not getting called in TextView.
   public func toolBarButtonAction(actionType: ToolBarActionType) {
       switch actionType {
    
         case .style:
print("style is pressed")
          
       case .undo:
         print("style is pressed")
       case .redo:
         print("style is pressed")
       }
     }
}

Only the 1st views delegate method is called but not the 2nd views. Am I missing something here? Thank you!

CodePudding user response：

I think that super.init() need to call so you can use delegate method

CodePudding user response：

The delegate exists in ToolbarView where as you're initialising Toolbar object. Maybe try replacing

public class TextView: UIView, ToolBarDelegate {
    private var toolbar = ToolbarView()

    public init() {
        super.init(frame: .zero)
        toolbar.delegate = self
    }

    required init?(coder: NSCoder) {
        super.init(coder: coder)
        toolbar.delegate = self
    }

    //this method is not getting called in TextView.
    public func toolBarButtonAction(actionType: ToolBarActionType) {
        switch actionType {
        case .style:
            print("style is pressed")
        case .undo:
            print("undo is pressed")
        case .redo:
            print("redo is pressed")
        }
    }
}
