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。
这样解决的最简单的方法是：重启设备（IPad，iPhone，iPod）等
