我有2个控制器:
(1) - > (2a - 2)
VC之间定制Segue导航:
当我使用普通segue时: 第二个控制器(包括导航栏!!!)从右侧推送第一个控制器
当我使用unwind segue时: 第一个控制器推动第二个控制器(没有导航栏!!!仅在导航控制器内查看)到右侧。导航栏很粘!当导航完成栏消失时。
如何使用导航栏推送View Controller。
我的代码:
class CustomSegue: UIStoryboardSegue {
override func perform() {
let toViewController: UIViewController = self.destinationViewController as! UIViewController
let fromViewController: UIViewController = self.sourceViewController as! UIViewController
let containerView: UIView? = fromViewController.view.superview
let screenBounds: CGRect = UIScreen.mainScreen().bounds
let finalToFrame: CGRect = screenBounds
let finalFromFrame: CGRect = CGRectOffset(finalToFrame, -screenBounds.size.width, 0)
toViewController.view.frame = CGRectOffset(finalToFrame, screenBounds.size.width, 0)
containerView?.addSubview(toViewController.view)
UIView.animateWithDuration(0.5, animations: {
toViewController.view.frame = finalToFrame
fromViewController.view.frame = finalFromFrame
}, completion: { finished in
let fromVC: UIViewController = self.sourceViewController as! UIViewController
let toVC: UIViewController = self.destinationViewController as! UIViewController
fromVC.presentViewController(toVC, animated: false, completion: nil)
})
}
}
class CustomUnwindSegue: UIStoryboardSegue {
override func perform() {
let toViewController: UIViewController = self.destinationViewController as! UIViewController
let fromViewController: UIViewController = self.sourceViewController as! UIViewController
let containerView: UIView? = fromViewController.view.superview
let screenBounds: CGRect = UIScreen.mainScreen().bounds
let finalToFrame: CGRect = screenBounds
let finalFromFrame: CGRect = CGRectOffset(finalToFrame, screenBounds.size.width, 0)
toViewController.view.frame = CGRectOffset(finalToFrame, -screenBounds.size.width, 0)
containerView?.addSubview(toViewController.view)
UIView.animateWithDuration(0.5, animations: {
toViewController.view.frame = finalToFrame
fromViewController.view.frame = finalFromFrame
}, completion: { finished in
let fromVC: UIViewController = self.sourceViewController as! UIViewController
let toVC: UIViewController = self.destinationViewController as! UIViewController
fromVC.dismissViewControllerAnimated(false, completion: nil)
})
}
}
答案 0 :(得分:0)
在前向segue中,您将动画从VC1到VC2a,它将成为segue的目标。动画VC2a也会使VC2出现,因为VC2a将其作为其视图的一部分。所以UINavigationBar和VC2都会滑入。
在反向segue中,您将动画从VC2到VC1。 VC2的view
没有涵盖整个屏幕,因为有些是由UINavigationBar占用的。您将VC2的视图设置为侧面并将其替换为VC1,当完成后,您dismissViewControllerAnimated
会导致VC2a在没有动画的情况下消失。
您需要再次为VC2a的视图设置动画,而不是在反向segue中设置VC2的视图动画。这应该随身携带VC2。我没有尝试过这段代码,但是这样的话:
UIView.animateWithDuration(0.5, animations: {
toViewController.view.frame = finalToFrame
VC2a.view.frame = finalFromFrame
}
