ios - 带有 viewWillTransitionToSize 和 Xcode 6.3 的 EXC_BAD_ACCESS

Question

这段代码曾经在我们今天的扩展中工作，但现在使用 Xcode 6.3 时出现 EXC_BAD_ACCESS。新问题是什么？

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

有人向我提到他们认为这是一个 Apple 错误。这是一个变通方法(或解决方案):

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")
    }
}
