Question

我在创建自定义segue时遇到问题：我重写了＆＃34; perform（）＆＃34;方法如下

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，＆＃34; destinationViewController＆＃34;中的旋转方法没有被召唤。所以，如果我锁定＆＃34; sourceViewController＆＃34;离开＆＃34; destinationViewController＆＃34;到肖像模式解锁后者不会旋转。

假设问题出在此行： self.sourceViewController.view.addSubview(self.destinationViewController.view) 我该如何更改代码以修复旋转？

好的家伙我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最终会像演示一样做同样的操作。所以在你必须创建动画之前，然后出现。当你需要在获取屏幕快照之前解散而没有动画时解除源VC（在解除之前在目标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是说话就是芯片我会显示代码。

编辑：我的代码中有一个小小的不精确。为了防止动画问题，只需在当前内部设置o dismiss complanion你的动画。

自定义UIStoryboardSegue - UIViewController supportedInterfaceOrientations永远不会调用
