在视图控制器,OS X之间转换 [英] Transitioning between view controller, OS X
问题描述
我想写一个单一的窗口计时器应用程序,当用户按下开始按钮我想它显示另一个视图控制器倒计时等。我也使用故事板在Xcode,我有一个segue其连接开始按钮和第二视图控制器。然而,只有三种不同的风格,即模态,表格和弹出。我想替换第一个视图控制器第二个在窗口中。我找不到办法。我试图使用自定义样式为segue,并在使用presentViewController:animator:方法,但我不知道什么作为动画的参数:。
I am trying to write a single window timer application, where when the user presses the start button I want it to show another view controller with countdown etc. I'm also using story board in Xcode, where I have got a segue which connects the start button and the second view controller. However, there are only three different styles i.e. modal, sheet, and pop-over. I want to replace the first view controller the second one in the window. I cannot find a way to do that. I tried using a custom style for the segue, and in that use presentViewController: animator: method but I cannot figure out what to send as the argument for the animator:.
在一个窗口中从一个视图控制器转换到另一个视图控制器的最简单/正确的方法是什么?
What is the simplest/proper way to transition from one view controller to the other in one window and vice versa?
当我选择视图控制器时,在storyboard中显示一个名为Presentation的属性,它可以是多个和单个的,这些属性是什么?
Also in the storyboard when I select a view controller it shows an attribute called "Presentation" which can be multiple and single, what do those represent?
推荐答案
我认为最简单的方法是交换 NSWindow
的 contentViewController
I think the simplest way is that swapping contentViewController
of NSWindow
.
// in NSViewController's subclass
@IBAction func someAction(sender: AnyObject) {
let nextViewController = ... // instantiate from storyboard or elsewhere
if let window = view.window where window.styleMask & NSFullScreenWindowMask > 0 {
// adjust view size to current window
nextViewController.view.frame = CGRectMake(0, 0, window.frame.width, window.frame.height)
}
view.window?.contentViewController = nextViewController
}
#1。
如果要使用segue,请创建自定义一个,并将其设置为IB中的标识符为segue类。
If you want to use segue, create custom one and set it to segue class with identifier in IB.
class ReplaceSegue: NSStoryboardSegue {
override func perform() {
if let fromViewController = sourceController as? NSViewController {
if let toViewController = destinationController as? NSViewController {
// no animation.
fromViewController.view.window?.contentViewController = toViewController
}
}
}
}
这是选项#2。
最后一个选项是使用 presentViewController:animator:
NSViewController
。下面的代码是用于溶解动画的自定义 NSViewControllerPresentationAnimator
。
Last option is using presentViewController:animator:
of NSViewController
. The code below is custom NSViewControllerPresentationAnimator
for dissolve animation.
class ReplacePresentationAnimator: NSObject, NSViewControllerPresentationAnimator {
func animatePresentationOfViewController(viewController: NSViewController, fromViewController: NSViewController) {
if let window = fromViewController.view.window {
NSAnimationContext.runAnimationGroup({ (context) -> Void in
fromViewController.view.animator().alphaValue = 0
}, completionHandler: { () -> Void in
viewController.view.alphaValue = 0
window.contentViewController = viewController
viewController.view.animator().alphaValue = 1.0
})
}
}
func animateDismissalOfViewController(viewController: NSViewController, fromViewController: NSViewController) {
if let window = viewController.view.window {
NSAnimationContext.runAnimationGroup({ (context) -> Void in
viewController.view.animator().alphaValue = 0
}, completionHandler: { () -> Void in
fromViewController.view.alphaValue = 0
window.contentViewController = fromViewController
fromViewController.view.animator().alphaValue = 1.0
})
}
}
}
然后像这样显示VC。
@IBAction func replaceAction(sender: AnyObject) {
let nextViewController = ... // instantiate from storyboard or elsewhere
presentViewController(nextViewController, animator: ReplacePresentationAnimator())
}
@IBAction func dismissAction(sender: AnyObject) {
presentingViewController?.dismissViewController(self)
}
