我看WWDC 2014的視頻A Look Inside Presentation Controllers
我下載會話的源代碼(寫在Objective-C
),嘗試構建它,我得到這個錯誤:爲UIPresentationController無可見@interface聲明選擇initWithPresentingViewController:presentedViewController
No visible @interface for UIPresentationController declares the selector initWithPresentingViewController:presentedViewController.
該方法是否假設在UIPresentationController
?
