这是我的分机:
extension UIViewController: UIViewControllerTransitioningDelegate {
func presentAssignBookToClassesViewController(controller: BWAssignBookToClassesViewController) {
controller.modalPresentationStyle = .Custom
controller.transitioningDelegate = self
controller.preferredContentSize = CGSizeMake(500, 575)
presentViewController(controller, animated: true, completion: nil)
}
func presentSettingsStoryboard() {
if let settingsController = UIStoryboard(name: "TeacherSettingsStoryboard", bundle: nil).instantiateInitialViewController() {
settingsController.modalPresentationStyle = .Custom
settingsController.transitioningDelegate = self
settingsController.preferredContentSize = CGSizeMake(500, 575)
presentViewController(settingsController, animated: true, completion: nil)
}
}
//MARK: - UIViewControllerTransitioningDelegate
public func presentationControllerForPresentedViewController(presented: UIViewController, presentingViewController presenting: UIViewController, sourceViewController source: UIViewController) -> UIPresentationController? {
return BWOverlayPresentationController(presentedViewController: presented, presentingViewController: presenting)
}
}
在 presentationControllerForPresentedViewController: 中，我需要根据调用的方法返回 BWOverlayPresentationController 或 BWSettingsPresentationController。如何实现？
最佳答案
你可以简单地通过restorationIdentifier来区分它们(你可以简单地使用storyboard来设置):
//MARK: - UIViewControllerTransitioningDelegate
public func presentationControllerForPresentedViewController(presented: UIViewController, presentingViewController presenting: UIViewController, sourceViewController source: UIViewController) -> UIPresentationController? {
if presented.restorationIdentifier == BWSettingsRestorationIdentifier {
return BWSettingsPresentationController(presentedViewController: presented, presentingViewController: presenting)
} else {
return BWOverlayPresentationController(presentedViewController: presented, presentingViewController: presenting)
}
}
