关于Parse库的配置问题

在使用Parse的一些相关服务时候，需要下载Parse的SDK,除了需要添加相应的系统框架和库的支持

AudioToolbox.framework

CFNetwork.framework
CoreGraphics.framework
CoreLocation.framework
libz.1.1.3.dylib
MobileCoreServices.framework
QuartzCore.framework
Security.framework
StoreKit.framework
SystemConfiguration.framework

假如你更改导入其他静态库时设置了，Linking下面的Other Linker Flags（比如:我在使用芒果广告平台，配置芒果平台的静态库：点击程序Target文件,选择Build Settings标签页,找到Linking下面的Other Linker Flags,添加参 数-all_load -ObjC。）但是这和Parse静态库设置冲突需要以移除 -ObjC，否则导致如下错误

Undefined symbols for architecture i386:

解决办法一：网上下载FaceBookSDK.framework,加入里面即可解决这些错误(文件比较大)

解决方法二：设置单独的静态库，使用-force_load /path/libname.a  来代替之前需要配置 -all_load _ObjC (比如下图：)
