需求：点击某个地方触发事件，可以自由的切换测试、预生产、生产三种环境。
原理：用NSUserDefault或者Singleton去维护环境变量集合。
宏定义配置

FBChangeEnvironment.h类

#import <Foundation/Foundation.h> @interface FBChangeEnvironment : NSObject MACRO_SHARED_INSTANCE_INTERFACE //切换环境 - (void)changeEnvironment; //获得当前环境 - (NSString *)currentEnvironment; @end |

FBChangeEnvironment.m
备注：下面devConfig、prodConfig、prodConfig1改为自己服务器3种环境的地址

某个地方需要调用事件时，调用以下方法即可
|
- (void)changeEnvironment { [[FBChangeEnvironment sharedInstance]changeEnvironment]; } |
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #000000; background-color: #ffffff }
