Mac 10.9 Mavericks中的Xcode啟動應用程序錯誤

Question

我使用MacOSX 10.9.3 Maverick，xcode 5.1.1。 我嘗試在模擬器中啟動應用程序，但發生黑屏並關閉xcode。 這是通知：

如何解決？

Answer 1

避免此問題的解決方案和解決方法：

選項A（解決方案）-確保您的/ etc / hosts文件包含以下條目：

127.0.0.1       localhost

選項B（解決方法）-如果確實必須將127.0.0.1映射為其他映射，例如我碰巧也在進行一些Facebook API測試，要求將其設置為local.mysite.com，則禁用Xcode調試器：

Product -> Scheme -> Edit Scheme -> Debugger -> None

也將解決此問題。

Answer 2

問題可能是由另一個刪除主機文件的應用程序引起的，例如MAMP PRO Recreate hosts文件

## 
# Host Database 
# 
# localhost is used to configure the loopback interface 
# when the system is booting.  Do not change this entry. 
## 
127.0.0.1       localhost 
255.255.255.255 broadcasthost 
::1             localhost  
fe80::1%lo0     localhost
