Question

我的应用启动，我在 tabBarController

的顶部显示 VC1
tabBarController?.present(VC1, animated: false, completion: nil)

它显示第一页，我有另一页 VC2。我通过向 tabBarController 中当前打开的 VC0 发布通知来在这两个页面之间进行翻转转换（ 不是显示的那个，而是索引 0 中的那个tabBarController)。通知触发：

if var topController = UIApplication.shared.keyWindow?.rootViewController { while let presentedViewController = topController.presentedViewController { topController = presentedViewController } let VC2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(identifier: "VC2") as! VC2 UIView.transition(from: topController.view, to: VC2.view, duration: 0.85, options: [.transitionFlipFromLeft]) }

这实现了翻转，但看起来 IBOutlets 未连接且未检测到点击。

如果是 VC2，您还没有保留任何参考资料。所以 IBOutlet 的动作不执行。你可以试试这个例子。可能对你有帮助。

ViewController.swift

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func gotoNextPage(_ sender: Any) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "SecondViewController")
        GlobalVariable.transitionViewFrom(from: self, to: vc, subtype: nil, options: [.transitionFlipFromLeft])
    }
}

class GlobalVariable: NSObject {
    private static var sharedManager: GlobalVariable!
    public var allViewInstantController: [UIViewController]=[UIViewController]()
    public static let NUMBER_OF_VIEWCONTROLLER_OPEN_AT_A_TIME:Int = 5

    static func shared() -> GlobalVariable {
        if(sharedManager==nil){
            sharedManager=GlobalVariable()
        }
        return sharedManager
    }
    override private init() {
    }

    static func transitionViewFrom(from:UIViewController, to:UIViewController, subtype:CATransitionSubtype? = nil, options: UIView.AnimationOptions? = nil) -> Void {
        let timeDelay:Double=0.5
        GlobalVariable.checkPreviousView(_view:to)
        GlobalVariable.splashViewFrom(from: from, to:to, isAdd:true, subtype:subtype, options: options, timeDelay: timeDelay)
    }

    static func checkPreviousView(_view:UIViewController) -> Void {
        GlobalVariable.shared().allViewInstantController.append(_view)
        if(GlobalVariable.shared().allViewInstantController.count>GlobalVariable.NUMBER_OF_VIEWCONTROLLER_OPEN_AT_A_TIME){
            let myViewController = GlobalVariable.shared().allViewInstantController.first
            myViewController?.view.removeFromSuperview()
            GlobalVariable.shared().allViewInstantController.removeFirst()
        }
    }

    static func splashViewFrom(from:UIViewController, to:UIViewController, isAdd:Bool, subtype:CATransitionSubtype? = nil, options: UIView.AnimationOptions? = nil, timeDelay:Double) -> Void {
        do {
            if let subtype = subtype {
                let transition = CATransition()
                transition.duration = 0.25
                transition.isRemovedOnCompletion = true;
                transition.timingFunction = CAMediaTimingFunction(name:CAMediaTimingFunctionName.easeInEaseOut)
                transition.type = CATransitionType.push
                transition.subtype  = subtype
                from.view.layer.add(transition, forKey: kCATransition)
            }else if let options = options {
                UIView.transition(from: from.view, to: to.view, duration: timeDelay, options: options)
            }

            if(!isAdd){
                from.view.removeFromSuperview()
                if(GlobalVariable.shared().allViewInstantController.count>0){
                    GlobalVariable.shared().allViewInstantController.removeLast()
                }
            }else{
                if subtype != nil {
                    from.view.addSubview(to.view)
                }
            }
        }
    }

    static func dismissViewFrom(viewController:UIViewController, subtype:CATransitionSubtype) -> Void {
        let timeDelay=0.5
        GlobalVariable.splashViewFrom(from: viewController, to: UIViewController(), isAdd:false, subtype:subtype, timeDelay: timeDelay)
    }
}

第二ViewController.swift

import UIKit

class SecondViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

    }
    @IBAction func previousPage(_ sender: Any) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "ViewController")
        GlobalVariable.transitionViewFrom(from: self, to: vc, subtype: nil, options: [.transitionFlipFromLeft])
    }
}

翻转只需更改类型。并相应地更改后页交易。

transition.type = CATransitionType(rawValue: "flip")

另一种解决方案，你可以试试这个。

ViewController.swift

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        GlobalVariable.shared().rootViewController=self
    }
    @IBAction func gotoNextPage(_ sender: Any) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "SecondViewController")
        UIView.transition(from: self.view, to: vc.view, duration: 0.5, options: [.transitionFlipFromLeft])
    }
}

class GlobalVariable: NSObject {
    private static var sharedManager: GlobalVariable!
    public var rootViewController: UIViewController?
    static func shared() -> GlobalVariable {
        if(sharedManager==nil){
            sharedManager=GlobalVariable()
        }
        return sharedManager
    }
    override private init() {
    }
}

第二ViewController.swift

import UIKit

class SecondViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        GlobalVariable.shared().rootViewController=self
    }

    @IBAction func previousPage(_ sender: Any) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "ViewController")
        UIView.transition(from: self.view, to: vc.view, duration: 0.5, options: [.transitionFlipFromLeft])
    }
}

Swift - 翻转视图控制器禁用 IBOutlets

Swift - Flipping view controllers disables IBOutlets
