EXC_BAD_ACCESS with viewWillTransitionToSize和Xcode 6.3

Question

此代碼用於在我們今天的擴展中工作，但現在使用Xcode 6.3的EXC_BAD_ACCESS。新問題是什麼？

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) { 
    coordinator.animateAlongsideTransition({ context in 
     self.tableView.frame = CGRectMake(0, 0, size.width, size.height) 
     }, completion: nil) 
} 

Answer 1

有人向我提到他們認爲這是一個蘋果的bug。以下是解決方法（或解決方案）：

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) 
{ 
    super.viewWillTransitionToSize(size, withTransitionCoordinator: coordinator) 

    if let safeCoordinator = coordinator as UIViewControllerTransitionCoordinator? 
    { 
     println("coordinator != nil") 
     safeCoordinator.animateAlongsideTransition({ context in 
      self.tableView.frame = CGRectMake(0, 0, size.width, size.height) 
      }, completion: nil) 

    } 
    else 
    { 
     println("coordinator == nil") 
    } 
}
