Question

我收到了以下崩溃报告：

Crashed: com.apple.main-thread

传播到代码，用户tapps tabbar按钮（我使用自定义tabbar）：

@IBAction func cameraControllerSelected()
{
    setUpTabBar(forSelectedActionSignContainer: cameraSign)
}

以下代码执行：

private func setUpTabBar ( forSelectedActionSignContainer imageView : UIImageView ) -> Void
{

    var viewControllerIndex = 0

    if ( imageView == feedSign )
    {
        feedSign.hidden = false
        exploreSign.hidden = true
        cameraSign.hidden = true
        chatSign.hidden = true
        profileSign.hidden = true
        viewControllerIndex = 0
    }
    if ( imageView == exploreSign )
    {
        feedSign.hidden = true
        exploreSign.hidden = false
        cameraSign.hidden = true
        chatSign.hidden = true
        profileSign.hidden = true
        viewControllerIndex = 1
    }
    if ( imageView == cameraSign )
    {
        feedSign.hidden = true
        exploreSign.hidden = true
        cameraSign.hidden = false
        chatSign.hidden = true
        profileSign.hidden = true
        viewControllerIndex = 2
    }
    if ( imageView == chatSign )
    {
        feedSign.hidden = true
        exploreSign.hidden = true
        cameraSign.hidden = true
        chatSign.hidden = false
        profileSign.hidden = true
        viewControllerIndex = 3
    }
    if ( imageView == profileSign )
    {
        feedSign.hidden = true
        exploreSign.hidden = true
        cameraSign.hidden = true
        chatSign.hidden = true
        profileSign.hidden = false
        viewControllerIndex = 4
    }


   if ( !shouldDismissTopOrReload(viewControllerAtIndex: viewControllerIndex))
   {
        displayViewController(atIndex: viewControllerIndex)
        signOnScreen = imageView
   }
}

它只出现在发布版本上，调试一切都很好。是优化编译器问题吗？因为我有相同的程序setUpTabbar()没有参数。其他功能 - 例如shouldDismissTopOrReload(viewControllerAtIndex: viewControllerIndex)和displayViewController(atIndex: viewControllerIndex)是可靠的，并且通过测试很好地覆盖。有任何想法吗？我有近200次崩溃!!

奇怪的EXC_BREAKPOINT迅速
