ios - 自定义 UIStoryboardSegue - UIViewController 支持的InterfaceOrientations 从不调用

Question

我在创建自定义转场时遇到问题:我正在重写“perform()”方法，如下所示

override func perform() {
    if !isBack {
        self.destinationViewController.view.frame = CGRectMake(self.sourceViewController.view.frame.width, 0, self.sourceViewController.view.frame.width, self.sourceViewController.view.frame.height)
        self.sourceViewController.view.addSubview(self.destinationViewController.view)
        self.sourceViewController.addChildViewController(self.destinationViewController)
        print("Source: \(self.sourceViewController) ---> Destination: \(self.destinationViewController)")
        UIView.animateWithDuration(0.5, animations: { () -> Void in
            self.destinationViewController.view.frame = CGRectMake(0, 0, self.destinationViewController.view.frame.width, self.destinationViewController.view.frame.height)
            }, completion: { (bolean) -> Void in
                print("Animation Completed")
        })

    }else{
        print("Source: \(self.sourceViewController) ---> Destination: \(self.destinationViewController)")
        UIView.animateWithDuration(0.5, animations: { () -> Void in
            self.sourceViewController.view.frame = CGRectMake(self.sourceViewController.view.frame.width, 0, self.sourceViewController.view.frame.width, self.sourceViewController.view.frame.height)
            }, completion: { (bolean) -> Void in
                print("Animation Completed")

                self.sourceViewController.view.removeFromSuperview()
        })
    }

一切运行正常，但此时，“destinationViewController”中的旋转方法尚未被调用。因此，如果我将“sourceViewController”锁定为纵向模式，同时保持“destinationViewController”解锁，则后者不会旋转。

假设问题出在这一行:self.sourceViewController.view.addSubview(self.destinationViewController.view)我应该如何更改代码来修复旋转？

好吧，我已经找到了这样的解决方案。

override func perform() {
    if !isBack {
        self.destinationViewController.view.frame = CGRectMake(self.sourceViewController.view.frame.width, 0, self.sourceViewController.view.frame.width, self.sourceViewController.view.frame.height)

        let window = UIApplication.sharedApplication().keyWindow
        window?.insertSubview(self.destinationViewController.view, aboveSubview: self.sourceViewController.view)

        print("Source: \(self.sourceViewController) ---> Destination: \(self.destinationViewController)")
        UIView.animateWithDuration(0.5, animations: { () -> Void in
            self.destinationViewController.view.frame = CGRectMake(0, 0, self.destinationViewController.view.frame.width, self.destinationViewController.view.frame.height)
            }, completion: { (bolean) -> Void in
                print("Animazione Terminata")
                self.sourceViewController.presentViewController(self.destinationViewController, animated: false, completion: nil)
        })

    }else{
        print("Indietro Source: \(self.sourceViewController) ---> Destination: \(self.destinationViewController)")

        let snapshot = self.sourceViewController.view.snapshotViewAfterScreenUpdates(false)
        snapshot.frame = CGRectMake(0, 0, snapshot.frame.size.width, snapshot.frame.size.height)
        self.destinationViewController.view.addSubview(snapshot)
        self.sourceViewController.dismissViewControllerAnimated(false, completion: nil)
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            UIView.animateWithDuration(0.5, animations: { () -> Void in
                snapshot.frame = CGRectMake(self.destinationViewController.view.frame.width, 0, self.destinationViewController.view.frame.width, self.destinationViewController.view.frame.height)
                }, completion: { (bolean) -> Void in
                    print("Animazione Terminata")
                    snapshot.removeFromSuperview()
            })
        })
    }
}

我已经明白 UIStoryboar 最终会像演示文稿一样执行相同的操作。所以在你必须创建动画之前，然后呈现。当您需要在获取屏幕快照之前关闭时，关闭不带动画的源 VC(在关闭之前在目标 VC 中添加快照)并最终为快照设置动画。

tnx 并购买。

抱歉我的英语不好，但谈话就是芯片，我展示了代码。

编辑:我的代码有点不精确。为了防止动画问题，只需在当前状态中设置或关闭动画即可。
