Question

我使用的是MacOSX 10.9.3 Maverick，xcode 5.1.1。我尝试在模拟器中启动应用程序，但发生黑屏并关闭xcode。这是注意：

如何解决？

Answer 1

避免此问题的解决方案和解决方法：

选项A（解决方案） - 确保/ etc / hosts文件包含此条目：

127.0.0.1       localhost

选项B（解决方法） - 如果你真的必须以不同的方式映射127.0.0.1，例如我碰巧也做了一些Facebook API测试，需要将它设置为local.mysite.com，禁用Xcode调试器：

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

也将解决此问题。

Answer 2

问题可能是由另一个删除了hosts文件的应用程序引起的，例如MAMP PRO 重新创建主机文件

## 
# 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
