在 Swift 中创建自定义 UIView 并显示为弹出窗口

Question

我正在尝试创建一个自定义 UIView 并使用 Swift 在我的主视图中将其显示为弹出窗口。

我的自定义UIView 代码是

class DatePopUpView: UIView {
var uiView:UIView?

override init()  {
    super.init()
    self.uiView = NSBundle.mainBundle().loadNibNamed("DatePopUpView", owner: self, options: nil)[0] as? UIView

}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
      }

required override init(frame: CGRect) {
           super.init(frame: frame)

}

}

我在主视图中将其称为：

 @IBAction func date_button_pressed (sender : AnyObject?) {
 var popUpView = DatePopUpView()
 var centre : CGPoint = CGPoint(x: self.view.center.x, y: self.view.center.y)

    popUpView.center = centre
    popUpView.layer.cornerRadius = 10.0
  let trans = CGAffineTransformScale(popUpView.transform, 0.01, 0.01)
    popUpView.transform = trans
    self.view .addSubview(popUpView)
    UIView .animateWithDuration(0.5, delay: 0.0, options:     UIViewAnimationOptions.CurveEaseInOut, animations: {

        popUpView.transform = CGAffineTransformScale(popUpView.transform, 100.0, 100.0)

        }, completion: {
            (value: Bool) in

    })

 }

但是 popUp 不会出现。我使用了断点并注意到值被分配给我的 popUpView 但它仍然没有显示在我的主视图上。请帮忙

请注意：我将 StoryBoard 用于我的 mainView 和我使用 xib 制作的自定义视图。

尝试将您的视图修改为以下内容：

class DatePopUpView: UIView {
     var uiView:UIView?
     override init()  {
         super.init()
         self.setup()
     }
     required init(coder aDecoder: NSCoder)  {
         super.init(coder: aDecoder)
         self.setup()
     }
     override init(frame: CGRect)   {
         super.init(frame: frame)
         self.setup()
     }
     setup() {
         self.uiView = NSBundle.mainBundle().loadNibNamed("DatePopUpView", owner: self, options: nil)[0] as? UIView
         self.uiView.frame = self.bounds
         self.uiView.autoresizingMask = .FlexibleWidth | .FlexibleHeight
         self.addSubview(self.uiView)
     }
}

在故事板中

• 在storyboard中创建一个UIViewController
• 将自定义类设置为 anotherViewController 并将 Storyboard_ID 设置为 another_view_sid
• 创建一个新的 Cocoa Touch 类作为 anotherViewController 和 UIVIewController 的子类

在视图控制器中

    let popvc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "another_view_sid") as! anotherViewController

    self.addChildViewController(popvc)

    popvc.view.frame = self.view.frame

    self.view.addSubview(popvc.view)

    popvc.didMove(toParentViewController: self)

在另一个视图控制器中

override func viewDidLoad() {
    super.viewDidLoad()
        showAnimate()
    }
}

@IBAction func Close_popupView(_ sender: Any) {
    removeAnimate()
}

func showAnimate()
{
    self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
    self.view.alpha = 0.0
    UIView.animate(withDuration: 0.25, animations: {
        self.view.alpha = 1.0
        self.view.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
    })
}

func removeAnimate()
{
    UIView.animate(withDuration: 0.25, animations: {
        self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
        self.view.alpha = 0.0
    }, completion: {(finished : Bool) in
        if(finished)
        {
            self.willMove(toParentViewController: nil)
            self.view.removeFromSuperview()
            self.removeFromParentViewController()
        }
    })
}

将视图呈现为模态转场

查看本教程：

http://makeapppie.com/2014/08/30/the-swift-swift-tutorials-adding-modal-views-and-popovers/

您可以使用系统提供的转场转场或进行自定义转场转场以获得真正精美的效果。

这是制作自定义过渡动画师的一种方法：

//
//  BaseTransitionAnimator.swift
//

import UIKit

class BaseTransitionAnimator : NSObject, UIViewControllerAnimatedTransitioning {

    enum PresentationMode {
        case Presenting, Dismissing
    }
    var duration     : NSTimeInterval = 1.0
    var mode         : PresentationMode = .Presenting

    init(duration: NSTimeInterval, mode: PresentationMode) {
        self.duration = duration
        self.mode = mode
    }

    func transitionDuration(transitionContext: UIViewControllerContextTransitioning) -> NSTimeInterval {
        return duration
    }

    func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
        // stub - must be overriden by inheritor
    }

---

//
//  ExpandingTransitionAnimator.swift
//

import UIKit

class ExpandingTransitionAnimator : BaseTransitionAnimator {

    enum ExpansionMode {
        case Basic, WithFadingImage
    }

    var image : UIImage? = nil

    override init(duration: NSTimeInterval, mode: PresentationMode) {
        super.init(duration: duration, mode: mode)
    }

    override func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
        var fromVC             = transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!
        var toVC               = transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!
        var fromView           = fromVC.view
        var toView             = toVC.view
        var containerView      = transitionContext.containerView()
        var duration           = transitionDuration(transitionContext)
        var initialFrame       = transitionContext.initialFrameForViewController(fromVC)

        var imageView : UIImageView?
        if image != nil {
            imageView = UIImageView(image: image!.crop(CGPointMake(0, 0),  size: toView.frame.size))

        }
        if (mode == .Presenting) {  
                toView.transform = CGAffineTransformMakeScale(0.05, 0.05)
               var originalCenter = toView.center
                containerView.addSubview(toView)
                if imageView != nil {
                    imageView!.transform = CGAffineTransformMakeScale(0.05, 0.05);
                    containerView.addSubview(imageView!)
                }

                UIView.animateWithDuration(duration,
                    delay:0.0,
                    options:.CurveEaseInOut,
                    animations: {
                        if imageView != nil {
                            imageView!.alpha = 0.0
                            imageView!.transform =  CGAffineTransformMakeScale(1.0, 1.0)
                        }
                        toView.transform =  CGAffineTransformMakeScale(1.0, 1.0)
                        toView.center = originalCenter
                    },
                    completion: { _ in
                        transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
                })
        } else { // dismissing
            UIView.animateWithDuration(duration,
                animations: {
                    fromView.transform = CGAffineTransformMakeScale(0.05, 0.05)
                    fromView.center = toView.center
                },
                completion: { _ in
                    fromView.removeFromSuperview()
                    transitionContext.completeTransition(!transitionContext.transitionWasCancelled())
            })
        }
    }
}

在 DatePopUpView 中，您似乎正在加载 nib 文件，但实际上并未将其作为子视图添加到视图中。

Mili Shah 回答的 Swift 5 版本

let popvc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "another_view_sid") as! anotherViewController

self.addChild(popvc)
popvc.view.frame = self.view.frame
self.view.addSubview(popvc.view)
popvc.didMove(toParent: self)

@IBAction func Close_popupView(_ sender: Any) {
    removeAnimate()
}

func showAnimate() {
    self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
    self.view.alpha = 0.0
    UIView.animate(withDuration: 0.25, animations: {
        self.view.alpha = 1.0
        self.view.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
    })
}

func removeAnimate() {
    UIView.animate(withDuration: 0.25, animations: {
        self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
