Objective-C：尝试在ipad设备上显示应用程序时在控制台上获取错误？ [英] Objective-C : getting error on console while trying to display app on ipad device?

问题描述

我试图在iPad上显示我的iPhone / Ipad应用程序，但是收到这个错误，我早些时候在设备上检查了这个应用程序，但现在在控制台上发出错误。

  **警告：无法读取/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1（8C148）/Symbols/usr/lib/info/dns.so（文件）的符号没有找到）** 
  

**无法使用引导服务器注册com.domainname.abcdef 。错误：未知错误代码。

这通常意味着此进程的另一个实例已经在运行，或挂在调试器中。程序接收到的信号为SIGABRT。 p>

警告：无法读取/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1（8C148）/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib（文件未找到）**

我的应用程序在模拟器上工作正常，但在设备上提供此错误，前提是昨天它也在使用相同代码的设备上工作。 >

我重新启动了Xcode，删除了构建文件夹，但没有成功。

解决方案

Plz做如下...

重新启动 iOS模拟器然后重置内容和设置，然后删除 build 文件夹从目录路径，然后清理所有目标之后运行您的应用程序...

我不知道这个但是当我收到这个错误我做了同样的事情并解决了这个错误..

删除您的设备并再次连接..并重新启动XCode，然后重试。 。

I am trying to display my iphone/Ipad app on my iPad but getting this error, I checked this app on device earlier but now its giving error on console.

**warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/usr/lib/info/dns.so (file not found).**

**Couldn't register com.domainname.abcdef with the bootstrap server. Error: unknown error code.

This generally means that another instance of this process was already running or is hung in the debugger.Program received signal: "SIGABRT".

My application working fine on Simulator but giving this error on device provided that yesterday it was also working on device with same code.

I restarted Xcode , deleted build folder but no succes.

解决方案

Plz do as following...

Restart iOS Simulator and then Reset contents and settings and then delete build folder from directory path and then clean all targets after this run your application...

I am not sure about this but when i got this error I had done the same thing and solved this error..

Remove your device and connect it again.. and restart XCode and then try again..
