開發環境和發佈環境切換以方便測試

需求：點擊某個地方觸發事件，能夠自由的切換測試、預生產、生產三種環境。

原理：用NSUserDefault或者Singleton去維護環境變量集合。

宏定義配置

/***************單例模式宏**************/ #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類

 

#import <Foundation/Foundation.h>     @interface FBChangeEnvironment : NSObject MACRO_SHARED_INSTANCE_INTERFACE //切換環境 - (void)changeEnvironment; //得到當前環境 - (NSString *)currentEnvironment; @end

 

FBChangeEnvironment.m

備註：下面devConfig、prodConfig、prodConfig1改成本身服務器3種環境的地址

#import "FBChangeEnvironment.h" //UAT static NSString *const devConfig = @"0"; //預生產 static NSString *const prodConfig = @"1"; //生產 static NSString *const prodConfig1 = @"2";   @implementation FBChangeEnvironment   MACRO_SHARED_INSTANCE_IMPLEMENTATION(FBChangeEnvironment) //切換環境 - (void)changeEnvironment{     NSLog(@"change environment start");          NSString *title=@"切換環境";     NSString *subTitle=@"重啓後生效, 非測試人員請點擊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=@"當前環境爲 UAT";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //測試環境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"預生產" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //預生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生產" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];              } else if ([[self currentEnvironment] isEqualToString:prodConfig]) {         currentEnvironment=@"當前環境爲 預生產";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //測試環境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"預生產" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //預生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生產" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];     } else if ([[self currentEnvironment] isEqualToString:prodConfig1]) {         currentEnvironment=@"當前環境爲 生產";                  [alert addAction:[UIAlertAction actionWithTitle:@"UAT" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //測試環境             [[NSUserDefaults standardUserDefaults] setObject:devConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"預生產" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {             //預生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig forKey:@"serverFB"];         }]];         [alert addAction:[UIAlertAction actionWithTitle:@"生產" style:UIAlertActionStyleDestructive handler:^(UIAlertAction * _Nonnull action) {             //生產環境             [[NSUserDefaults standardUserDefaults] setObject:prodConfig1 forKey:@"serverFB"];         }]];     }            [alert addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {         //     }]];     //當前選擇的視圖控制器須要本身賦值，好比tabbar的didSelectViewController裏     [APPDelegate.currentSelectedVC.navigationController presentViewController:alert animated:YES completion:^{         //     }]; } //得到當前環境 - (NSString *)currentEnvironment{     //默認生產環境     NSString *currentEnvironment=prodConfig1;     if ([[NSUserDefaults standardUserDefaults] objectForKey:@"serverFB"]) {         currentEnvironment=[[NSUserDefaults standardUserDefaults] objectForKey:@"serverFB"];     }     return currentEnvironment; }   @end

 

某個地方須要調用事件時，調用如下方法便可

- (void)changeEnvironment {     [[FBChangeEnvironment sharedInstance]changeEnvironment]; }
