我有一个 Storyboard设置，在某些时候，一个按钮会用另一个按钮替换详细 View 。默认情况下，根本没有任何转换: View Controller 突然被替换。我可以创建一个吗？如何创建？
我的猜测是使用自定义转换 - 就像您通常为 View 更改使用自定义动画一样 - 但我不知道如何实现 Split View Controller 的“替换”行为。
最佳答案
我使用自定义segue 做到了这一点，当有 splitViewController 时，我会“显示详细信息”，否则我会尝试推送/呈现模式。全部动画化。显示模态动画将通过变换淡出旧 Controller 并通过变换更改显示新 Controller
class ShowDetailSegue: UIStoryboardSegue {
private let showFromScale : CGFloat = 0.8
private let hideToScale : CGFloat = 1.2
private let animationDuration : NSTimeInterval = 0.33
override func perform() {
let sourceVC = self.sourceViewController as! UIViewController
let destinationVC = self.destinationViewController as! UIViewController
let animated = true
if let splitVC = sourceVC.splitViewController where splitVC.isInSplitView {
// splitview with detail is visible, we will show detail with animation
showDetail(splitVC, sourceVC : sourceVC, destinationVC: destinationVC, animated: animated)
} else if let navController = sourceVC.navigationController {
// there is no split view – just push to navigation controller
sourceVC.navigationController?.pushViewController(destinationVC, animated: animated)
} else {
// no navigation found, let just present modal
sourceVC.presentViewController(destinationVC, animated: animated, completion: nil)
}
}
private func showDetail(splitVC : UISplitViewController, sourceVC : UIViewController, destinationVC : UIViewController, animated : Bool) {
let newDetailVC = GeneralNavigationController(rootViewController: destinationVC)
newDetailVC.applyAppearance()
if !animated {
splitVC.showDetailViewController(newDetailVC, sender: sourceVC)
} else {
var currentDetailVC = splitVC.viewControllers.last as! UIViewController
if let currentDetailNC = currentDetailVC as? UINavigationController {
currentDetailVC = currentDetailNC.topViewController
}
UIView.animateWithDuration(animationDuration / 2.0, animations: { () -> Void in
// hide the old view with transform
currentDetailVC.view.alpha = 0
currentDetailVC.view.transform = CGAffineTransformMakeScale(self.hideToScale, self.hideToScale)
currentDetailVC.navigationController?.navigationBar.alpha = 0
}, completion: { (completed) -> Void in
newDetailVC.navigationController?.navigationBar.alpha = 0
newDetailVC.view.alpha = 0
newDetailVC.view.transform = CGAffineTransformScale(newDetailVC.view.transform, self.showFromScale, self.showFromScale)
splitVC.showDetailViewController(newDetailVC, sender: sourceVC)
// Show new view
UIView.animateWithDuration(self.animationDuration / 2.0, animations: { () -> Void in
newDetailVC.view.alpha = 1
newDetailVC.view.transform = CGAffineTransformScale(newDetailVC.view.transform, 1 / self.showFromScale, 1 / self.showFromScale)
newDetailVC.navigationController?.navigationBar.alpha = 1
}, completion: { (completed) -> Void in
currentDetailVC.view.transform = CGAffineTransformScale(currentDetailVC.view.transform, 1 / self.hideToScale, 1 / self.hideToScale)
})
})
}
}
}
