我有1个来自Storyboard的MainViewController和1个来自xib的ModalUIView。
在ModalUIView中,具有用于显示模态的当前功能和用于关闭模态的关闭功能。
步:
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")
}
我的问题是当我调用modalUIView的present时出现了mainViewController,然后我在modalUIView中的closeButton上的选项卡未触发
我尝试使用@IBAction,但无法正常工作:
@IBAction func CloseButtonAction(_ sender: UIButton) {
}
我也尝试通过编程手动添加操作,但也无法正常工作:
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
最佳答案
好的,我现在有一个解决方案,但不确定是否是最佳答案。
我的解决方案是通过mainViewController将操作添加到modalUIView的closeButton中,而不是modalUIView中
如果还有其他最佳解决方案,请提出建议。
