iOS模拟器仅显示空白屏幕

Question

我已经将少数Macmini升级到El Capitan 10.11.2，并安装了Xcode 7.1。 但是iOS模拟器显示了一些问题。 就像Xcode 7.1的默认iOS是9.1，当我从SDK 9.1在iOS模拟器中启动任何设备时，它只会显示黑屏。

因此要检查，我去了Xcode> Preferences并下载了SDK 9.0和8.4。 当我从SDK 9.0或8.4切换到任何设备时，它们都可以正常工作。 但是我不知道默认的SDK 9.1是怎么回事。

我在下面尝试了一些方法来解决此问题。

1. 重新安装Xcode。
2. 重置设备内容。
3. 删除了设备文件夹，并在SDK 9.1下再次创建了设备。
4. 删除并使用正确的权限重新创建/ private / tmp /。
5. 多一点。

他们都没有工作。

当我切换到SDK 9.1下的任何设备时，我已经很好地粘贴了CoreSimulator.log的一些日志。

Answer 1

退出xcode并杀死pid，然后关闭并退出模拟器。 再次午餐xcode并转到窗口-> divices->删除所有设备并重新添加它，它将起作用。
