+//----------------------INSTALLATION 安装方法----------------------------
+
+//Added the prefix header file to PROJECT:
+//1.Creat a new PCH files and named it with "PrefixHeader.pch"(default name or anything you want) .
+//2.Click next and go to Build Settings search Prefix Header.
+//3.Double click the blank address and put this address: $(SRCROOT)/$(PROJECT_NAME)/PrefixHeader.pch
+//THEN YOU CAN USE THIS IN EVERY FILES IN THIS PROJECT. Good luck.
+
+//如何安装:
+//1.创建新pch文件,默认名字即可: "PrefixHeader.pch".
+//2.点击下一步再去Build Settings 搜索Prefix Header.
+//3.找到Prefix Header并且双击,输入$(SRCROOT)/$(PROJECT_NAME)/PrefixHeader.pch
+//现在你可以在项目内任何文件调用宏定义了,祝一切顺利.
+
+
+
+
+
+// Include any system framework and library headers here that should be included in all compilation units.
+// You will also need to set the Prefix Header build setting of one or more of your targets to reference this file.
