Ios 警告：segue之后无法加载任何Objective-C类信息

我试图在我的ios应用程序中使用自定义segue，当我执行segue时，它总是返回“警告：无法加载任何Objective-C类信息。这将显著降低可用类型信息的质量。”以及“EXC_BAD_ACCESS（code=2，address=0x7fff504faff8）”，这似乎是某种内存警告，但我不知道为什么

这是自定义的segue代码，它似乎在一个空白的项目中工作，但在我的项目中不工作，我似乎无法找出上面的错误意味着什么

以前有人见过这种错误吗？（我在这里的搜索没有返回任何与我看到的内容相同的内容）-我还包括了下面的堆栈跟踪的一部分

private func animateGrowScale() {
    let toViewController = destinationViewController
    let fromViewController = sourceViewController

    let containerView = fromViewController.view.superview
    let originalCenter = fromViewController.view.center

    toViewController.view.transform = CGAffineTransformMakeScale(0.05, 0.05)
    toViewController.view.center = originalCenter

    containerView?.addSubview(toViewController.view)

    UIView.animateWithDuration(0.5, delay: 0.0, options: UIViewAnimationOptions.CurveEaseInOut, animations: {
        toViewController.view.transform = CGAffineTransformMakeScale(1.0, 1.0)
        }, completion: { finished in
            let fromVC = self.sourceViewController
            let toVC = self.destinationViewController
            fromVC.presentViewController(toVC, animated: false, completion: nil)
    })
}

在哪里设置

sourceViewController

和

destinationViewController

？链接我的主故事板中的两个控制器，然后在firstviewcontroller中覆盖我的PrepareForegue，如下所示：

覆盖func PrepareForegue（segue:UIStoryboardSegue，sender:AnyObject？{如果segue是CustomSegue{（segue as！CustomSegue）.animationType=.GrowScale}}

我刚刚在重温一个旧项目时遇到了类似的问题，它现在崩溃了，出现了一个无限循环，与您在那里的最后6行相同，当显示摄影机视图的图像选择器时。@LastNightTrain我遇到了相同的问题，使用图像选择器，您解决了问题吗？@aircraft v抱歉，我现在只模糊地记得这一点，我瘦了k这可能与图像选取器的显示方式有关，抱歉，我不能说得更具体了！（猜测是我将显示从本地VC移开，并可能从window/rootVC进行显示）。HTH，祝你好运！
