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
|
/***************单例模式宏**************/ #define MACRO_SHARED_INSTANCE_INTERFACE +(instancetype)sharedInstance;
#define MACRO_SHARED_INSTANCE_IMPLEMENTATION(CLASS) \ +(instancetype)sharedInstance \ { \ static CLASS * sharedInstance = nil; \ static dispatch_once_t onceToken; \ dispatch_once(&onceToken, ^{ \ sharedInstance = [[CLASS alloc] init]; \ }); \ return sharedInstance; \ }
#define APPDelegate ((AppDelegate*)[UIApplication sharedApplication].delegate) |
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
|
#import "FBChangeEnvironment.h" //UAT static NSString *const devConfig = @"0"; //预生产 static NSString *const prodConfig = @"1"; //生产 static NSString *const prodConfig1 = @"2";
@implementation FBChangeEnvironment
MACRO_SHARED_INSTANCE_IMPLEMENTATION(FBChangeEnvironment) //切换环境 - (void)changeEnvironment{ NSLog(@"change environment start");

@end |
某个地方需要调用事件时，调用以下方法即可
|
- (void)changeEnvironment { [[FBChangeEnvironment sharedInstance]changeEnvironment]; } |
