iphone - iOS:如何在 iPhone 上触发用户强制退出崩溃？

Question

WWDC 视频(WWDC 2010 session 317 - 了解 iPhone 操作系统上的崩溃报告)说崩溃日志中的错误代码 0xdeadfa11 表示用户强制退出崩溃，但我从未见过此错误代码。如何触发用户强制退出崩溃？

编辑:我想知道手动方式和编程方式:P

Answer 1

显然没有编程的方法来做到这一点，因为异常类型是基于用户事件的。

为了模拟崩溃，苹果文档如下所示

The exception code 0xdeadfa11 indicated that an application has been force quit by the user. Force quits occur when the user first holds down the On/Off button until "slide to power off" appears, then holds down the Home button. It's reasonable to assume that the user has done this because the application has become unresponsive, but it's not guaranteed - force quit will work on any application.

我已经在 iphone 5 (iOS 7) 设备上模拟了这个并且工作正常。
