启动时崩溃 - ios 8.1 因为添加了 UIButton 的子视图。 EXC_BREAKPOINT（信号陷阱）
Crash at launch - ios 8.1 because adding UIButton's subview. EXC_BREAKPOINT (SIGTRAP)
我刚刚被 Apple 拒绝了，原因如下：
We were unable to review your app, as it crashed on launch on the
following device(s):
- iPhone 5S running iOS 8.1- iPhone 6 running iOS 8.1- iPhone 6 Plus running iOS 8.1
这是我所做的：
我确实用模拟器 ios 8.1,8.2 中的设备对其进行了测试。我还使用读取设备对其进行了测试：iphone 4 运行ning ios 7.1，ipad 运行ning ios 8.3。根本没有崩溃。
根据他们发送的崩溃日志，我使用 Symbolicator 生成以下符号化日志：

上面代码的意思是，我想创建一个类似Instagram的标签栏。所以我在 5 项选项卡栏中的 3 选项卡前面添加了一个按钮。在模拟器 ios 8.1 中如下所示：
1) 代码很简单，我无法找出它在 ios 8.1 中崩溃的原因。现在我没有真正的设备 运行ning ios 8.1 来测试它所以我问你是否可以在代码中找到异常的东西。
2) 是否有可能是因为配置文件有问题导致应用程序崩溃？但我认为这不是我的情况，因为我使用分发配置文件存档，并通过 iTunes 和 TestFlight 安装 ipa 到我的 ipad 它可以 运行 ok.
抱歉，问题很长。任何帮助将不胜感激！
更新 1：
我通过命令行符号再次确认崩溃，如here中西藏海岸的回答所述。然后我得到了崩溃必须在代码的第206行：
mapButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
这种启蒙肯定有问题。我没有为这个按钮使用情节提要，但我以编程方式创建。我的朋友使用 XCode 6.3（我用的是 6.2），打开我的项目时看到很多与 "as"、“！”相关的编译错误。和 ”？”。我想我要把我的 XCode 更新到 6.3，看看我是否有编译错误 "as" 在第 206 行。
通过将编辑方案中的构建配置设置为 Release for 运行，只需检查 运行 应用程序选项卡并查看崩溃是否仍然发生，它将帮助您进行调试，因为构建在发布模式下崩溃。我觉得它主要是 swift 编译器问题，如果是这样，您可以通过将 swift 编译器优化从最快更改为 none 来避免它。我不确定这是否是一个理想的解决方案，但看看是否有帮助。 :]
终于拿到真机进行测试了。它在以下行崩溃：
mapButton.autoresizingMask = UIViewAutoresizing.FlexibleBottomMargin|UIViewAutoresizing.FlexibleLeftMargin|UIViewAutoresizing.FlexibleRightMargin|UIViewAutoresizing.FlexibleTopMargin
原因：mapButton 为零。很奇怪，因为这条线就在上面：
mapButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
所以面对这个初始化程序不要初始化我的按钮。所以我可能同意 Chandan005 关于编译器问题的观点。我将代码更改为：
let frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height)
button = UIButton(frame: frame)
现在适用于 iPhone 6，ios 8.1。我再次提交了我的应用程序，希望这次能通过。我在我的博客中写到了这个错误 here。
我刚刚被 Apple 拒绝了，原因如下：
We were unable to review your app, as it crashed on launch on the following device(s): - iPhone 5S running iOS 8.1- iPhone 6 running iOS 8.1- iPhone 6 Plus running iOS 8.1

上面代码的意思是，我想创建一个类似Instagram的标签栏。所以我在 5 项选项卡栏中的 3 选项卡前面添加了一个按钮。在模拟器 ios 8.1 中如下所示：
1) 代码很简单，我无法找出它在 ios 8.1 中崩溃的原因。现在我没有真正的设备 运行ning ios 8.1 来测试它所以我问你是否可以在代码中找到异常的东西。
2) 是否有可能是因为配置文件有问题导致应用程序崩溃？但我认为这不是我的情况，因为我使用分发配置文件存档，并通过 iTunes 和 TestFlight 安装 ipa 到我的 ipad 它可以 运行 ok.
抱歉，问题很长。任何帮助将不胜感激！
更新 1： 我通过命令行符号再次确认崩溃，如here中西藏海岸的回答所述。然后我得到了崩溃必须在代码的第206行：
mapButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
这种启蒙肯定有问题。我没有为这个按钮使用情节提要，但我以编程方式创建。我的朋友使用 XCode 6.3（我用的是 6.2），打开我的项目时看到很多与 "as"、“！”相关的编译错误。和 ”？”。我想我要把我的 XCode 更新到 6.3，看看我是否有编译错误 "as" 在第 206 行。
通过将编辑方案中的构建配置设置为 Release for 运行，只需检查 运行 应用程序选项卡并查看崩溃是否仍然发生，它将帮助您进行调试，因为构建在发布模式下崩溃。我觉得它主要是 swift 编译器问题，如果是这样，您可以通过将 swift 编译器优化从最快更改为 none 来避免它。我不确定这是否是一个理想的解决方案，但看看是否有帮助。 :]
终于拿到真机进行测试了。它在以下行崩溃：
mapButton.autoresizingMask = UIViewAutoresizing.FlexibleBottomMargin|UIViewAutoresizing.FlexibleLeftMargin|UIViewAutoresizing.FlexibleRightMargin|UIViewAutoresizing.FlexibleTopMargin
原因：mapButton 为零。很奇怪，因为这条线就在上面：
mapButton = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
所以面对这个初始化程序不要初始化我的按钮。所以我可能同意 Chandan005 关于编译器问题的观点。我将代码更改为：
let frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height)
button = UIButton(frame: frame)
现在适用于 iPhone 6，ios 8.1。我再次提交了我的应用程序，希望这次能通过。我在我的博客中写到了这个错误 here。
