ios - 保存屏幕截图时 Xcode 8.2 模拟器崩溃

Question

更新XCode 8.2后，每次保存模拟器截图总是崩溃。即使我重置了内容和设置，仍然会崩溃。

我应该删除所有模拟器并重新安装它们吗？

更新:

• 8.2.1有同样的问题。
• 仅支持 8.3 Sierra。

Answer 1

崩溃似乎是由于调用 saveScreenShot: 选择器时的段错误，或者更具体地说是一般保护错误。发生这种情况的原因取决于多种因素，因此很难说重新安装是否有帮助。

无论如何，如果模拟器中的屏幕截图(⌘S)功能导致崩溃，您几乎无能为力。您最好的选择可能是提交 a bug report to Apple .

更新:

我刚刚更新到 8.2 GM，结果发现，我的 ⌘S 也崩溃了。虽然我得到的是 KERN_INVALID_ADDRESS 而不是 EXC_I386_GPFLT。

目前，一种解决方法是复制屏幕并粘贴到预览中:
