iOS模擬器僅顯示空白屏幕

Question

我已經將少數Macmini升級到El Capitan 10.11.2，並安裝了Xcode 7.1。 但是iOS模擬器顯示了一些問題。 就像Xcode 7.1的默認iOS是9.1，當我從SDK 9.1在iOS模擬器中啟動任何設備時，它只會顯示黑屏。

因此要檢查，我去了Xcode> Preferences並下載了SDK 9.0和8.4。 當我從SDK 9.0或8.4切換到任何設備時，它們都可以正常工作。 但是我不知道默認的SDK 9.1是怎么回事。

我在下面嘗試了一些方法來解決此問題。

1. 重新安裝Xcode。
2. 重置設備內容。
3. 刪除了設備文件夾，並在SDK 9.1下再次創建了設備。
4. 刪除並使用正確的權限重新創建/ private / tmp /。
5. 多一點。

他們都沒有工作。

當我切換到SDK 9.1下的任何設備時，我已經很好地粘貼了CoreSimulator.log的一些日志。

Answer 1

退出xcode並殺死pid，然后關閉並退出模擬器。 再次午餐xcode並轉到窗口-> divices->刪除所有設備並重新添加它，它將起作用。
