Xcode5.1.1支持低版本和image not found和Couldn't register XXXX with the bootstrap server. Error: unknown error code.

一：问题 targets中证书的设置

1.项目支持多设备（Xcode5.1.1支持低版本）

2.真机测试要确保Code Siging 设置没问题

支持的最低版本

二：问题：image not found

Library not loaded: /System/Library/Frameworks/AdSupport.framework/AdSupport

Referenced from: /var/mobile/Applications/0083F6DD-6466-48B4-8F6D-7AEC68FBC421/DPM.app/DPM

Reason: image not found

解决方法：

Found out the solution to the problem. The problem was setting the added frameworks as requiredinstead of optional

GO TO Project-> Targets-> Build Phases-> Link Binary with Libraries

There, set the status of added frameworks to Optional

This solved my problem.

三： Couldn't register XXX 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.

可能会想到是不是改动代码造成的，由于用模拟器就没问题，编译能正常通过，只是一到真机调试就报错，原因是由于在debug时，未停止debug而直接拔掉数据线导致的，可能是真机内任然保留有调试信息，真机认为自己依然处于调试状态，从而导致调试状态冲突而造成的。
