开发环境和发布环境切换以方便测试

Posted 2020-11-01 黄增松的技术博客

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");          NSString *title=@"切换环境";     NSString *subTitle=@"重启后生效, 非测试人员请点击cancel";     UIAlertController *alert = [UIAlertController alertControllerWithTitle:title message:subTitle preferredStyle:UIAlertControllerStyleActionSheet];               //修改title     NSMutableAttributedString *alertControllerStr = [[NSMutableAttributedString alloc] initWithString:title]; //    [alertControllerStr addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, alertControllerStr.length)];     [alertControllerStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20] range:NSMakeRange(0, alertControllerStr.length)];     [alert setValue:alertControllerStr forKey:@"attributedTitle"];          //修改message     NSMutableAttributedString *alertControllerMessageStr = [[NSMutableAttributedString alloc] initWithString:subTitle]; //    [alertControllerMessageStr addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(0, alertControllerMessageStr.length)];     [alertControllerMessageStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:16] range:NSMakeRange(0, alertControllerMessageStr.length)];     [alert setValue:alertControllerMessageStr forKey:@"attributedMessage"];            NSString *currentEnvironment=@"";     if ([[self currentEnvironment] isEqualToString:devConfig]) {         currentEnvironment=@"当前环境为 UAT";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //测试环境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"预生产" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //预生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生产" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];              } else if ([[self currentEnvironment] isEqualToString:prodConfig]) {         currentEnvironment=@"当前环境为 预生产";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //测试环境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"预生产" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //预生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生产" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];     } else if ([[self currentEnvironment] isEqualToString:prodConfig1]) {         currentEnvironment=@"当前环境为 生产";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //测试环境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"预生产" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //预生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生产" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //生产环境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];     }            [alert addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {         //     }]];     //当前选择的视图控制器需要自己赋值，比如tabbar的didSelectViewController里     [APPDelegate.currentSelectedVC.navigationController presentViewController:alert animated:YES completion:^{         //     }]; } //获得当前环境 - (NSString *)currentEnvironment{     //默认生产环境     NSString *currentEnvironment=prodConfig1;     if ([[NSUserDefaults standardUserDefaults] objectForKey:@"serverFB"]) {         currentEnvironment=[[NSUserDefaults standardUserDefaults] objectForKey:@"serverFB"];     }     return currentEnvironment; }   @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]; }
