類型 'AnimationController' 不符合協議 'UIViewControllerAnimatedTransitioning'

Question

import Foundation 
import UIKit 

enum TransitionType { 
    case Presenting, Dismissing 
} 

class AnimationController: NSObject, UIViewControllerAnimatedTransitioning { 
    var duration: NSTimeInterval 
    var isPresenting: Bool 
    var originFrame: CGRect 

    init(withDuration duration: NSTimeInterval, forTransitionType type: TransitionType, originFrame: CGRect) { 
     self.duration = duration 
     self.isPresenting = type == .Presenting 
     self.originFrame = originFrame 

     super.init() 
    } 

    func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval { 
     return self.duration 
    } 
}

這是錯誤的話。該代碼尚未完全採用UIViewControllerAnimatedTransitioning協議。您需要實施public func animateTransition(transitionContext: UIViewControllerContextTransitioning)，這發生在您鏈接到的文章的下一代碼塊中。
