开发环境和发布环境切换以方便测试

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];

}
