【问题描述】:
我有 1 个来自故事板的 MainViewController 和 1 个来自 xib 的 ModalUIView。
在 ModalUIView 中具有显示模态的呈现功能和关闭模态的关闭功能。
步骤: MainViewController -> OpenModal -> ModalUIView -> CloseModal
这是我的代码:
UIViewUtil.swift
import Foundation
import UIKit
extension UIView {
// Load xib as the same name of CustomView that want to use xib
func loadXib() -> UIView{
let bundle = Bundle(for: type(of: self))
let nibName = type(of: self).description().components(separatedBy: ".").last!
let nib = UINib(nibName: nibName, bundle: bundle)
return nib.instantiate(withOwner: self, options: nil).first as! UIView
}
}
MainViewController.swift 是 UIViewController 的子类
@IBAction func guideButton(_ sender: Any) {
let modal = ModalUIView()
modal.present(targetView: self.view)
}
ModalUIView.swift 是 UIView 的子类
var view : UIView?
override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
required init?(coder aDecoder: NSCoder)
{
super.init(coder: aDecoder)
setup()
}
func setup() {
view = loadXib()
}
func present(targetView: UIView) {
view!.layer.cornerRadius = 10.0
view!.clipsToBounds = true
targetView.addSubview(view!)
// Set size
let popupWidth: CGFloat = targetView.frame.width - (targetView.frame.width * 0.04)
let popupHeight: CGFloat = targetView.frame.height - (targetView.frame.height * 0.08)
view!.frame = CGRect(x: targetView.frame.origin.x, y: targetView.frame.origin.y,
width: popupWidth, height: popupHeight)
view!.center = targetView.center
view!.transform = CGAffineTransform.init(scaleX: 1.3, y: 1.3)
view!.alpha = 0
UIView.animate(withDuration: 0.4){
self.view!.alpha = 1
self.view!.transform = CGAffineTransform.identity
}
}
@objc func dismiss(sender: UIButton!) {
print("dismiss")
}
当我调用 modalUIView 的存在时,我的问题是 mainViewController,然后我在 modalUIView 中的 closeButton 选项卡上没有触发该操作
我尝试使用@IBAction,但它不起作用:
@IBAction func CloseButtonAction(_ sender: UIButton) {
}
我也尝试通过编程方式手动添加操作,但它也不起作用:
let closeButton: UIButton? = view?.viewWithTag(10) as! UIButton
closeButton!.addTarget(self, action: #selector(dismiss), for: .touchUpInside)
注意: 我可以看到并点击模式上的 closeButton。 我已经将 ModalUIView 添加到 xib 文件的所有者
