çökme Yönünü değiştirmeden sonra Segmeyi iptal et

Question

iOS 9.3'te yatay veya portrete iyi çalışan bir istem seggim var, ancak cihazı hedef görüntü denetleyicisi (A) ve görüntüleme denetleyicisi gerçekleştirme arasında döndürdüğümde aşağıdaki istisnayı atar gevşeyin (C).

Bunun neden olduğuyla ilgili herhangi bir fikir ve bu soruna nasıl bir çözüm bulursunuz? Benim film şeridinin

Answer 1

Çözülmüş. Sorun uygulama temsilci yöntemi olup:

func splitViewController(splitViewController: UISplitViewController, 
    collapseSecondaryViewController secondaryViewController: UIViewController, 
    ontoPrimaryViewController primaryViewController: UIViewController) -> Bool { 
    ... 
    return true 
} 

Bu yöntem splitViewController önce gevşemeye secondaryViewController olduğu hedef görünümü düğmeyi (A), çökmeye neden olan, doğru dönmek düştü. Çözüm, ikincinin yanlış döndürerek çökmediğinden emin olmak ve böylece gevşemenin hedefinin mevcut olmasını sağlamaktır.
