Firebase遠程配置崩潰（目標c iOS）

我無法從Firebase RemoteConfig獲取信息。在應用程序安裝中，我在MainController視圖控制器之前有一個語言選擇屏幕。在MainController視圖控制器上，我正在執行RemoteConfig提取。當語言選擇屏幕顯示在MainController視圖控制器之前時，它首次運行。但是，從下一次，它崩潰上這一行：Firebase遠程配置崩潰（目標c iOS）

[self.remoteConfig fetchWithExpirationDuration:expirationDuration completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) {

但下列情況除外：

UPDATE：，如果我表現出的語言選擇屏幕不要緊，或不。它始終在全新安裝上運行，並在下次啓動時停止工作。

這是我正在使用的完整代碼。

-(void)viewDidAppear:(BOOL)animated{ 
    //Display select language settings 
    if (![[NSUserDefaults standardUserDefaults] boolForKey:DISPLAY_LANGUAGE_SETTING]) 
    { 
     NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
     [defaults setBool:TRUE forKey:DISPLAY_LANGUAGE_SETTING]; 
     [defaults synchronize]; 
     //Display Language Screen 
     AGSelectLanguageViewController *languageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"AGSelectLanguageViewController"]; 
     self.modalPresentationStyle = UIModalPresentationFullScreen; 
     [self presentViewController:languageViewController animated:NO completion:nil]; 
    } 

    [self configFireBase]; 

} 
    -(void)configFireBase{ 
     // Firebase Configuration 
     self.remoteConfig = [FIRRemoteConfig remoteConfig]; 
     //Enabling development mode 
     FIRRemoteConfigSettings *remoteConfigSettings = [[FIRRemoteConfigSettings alloc] initWithDeveloperModeEnabled:YES]; 
     self.remoteConfig.configSettings = remoteConfigSettings; 

     //Set default Remote Config values 
     [self.remoteConfig setDefaultsFromPlistFileName:@"RemoteConfigDefaults"]; 

     [self fetchConfig]; 
    } 

- (void)fetchConfig { 
    _discount_percentage = self.remoteConfig[DISCOUNT_PERCENTAGE].numberValue.floatValue; 

    long expirationDuration = 3600; 

    if (self.remoteConfig.configSettings.isDeveloperModeEnabled) { 
     expirationDuration = 0; 
    } 


    [self.remoteConfig fetchWithExpirationDuration:expirationDuration completionHandler:^(FIRRemoteConfigFetchStatus status, NSError *error) { 
     if (status == FIRRemoteConfigFetchStatusSuccess) { 
      NSLog(@"Config fetched!"); 
      [self.remoteConfig activateFetched]; 
     } else { 
      NSLog(@"Config not fetched"); 
      NSLog(@"Error %@", error.localizedDescription); 
     } 
    }]; 
}

我在哪裏錯了？請幫忙。

的GIPLocale類做谷歌和蘋果的名稱爲不同語言環境之間的一些映射，併爲它拉應用程序的語言環境從NSUserDefaults的一部分：

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; 
NSArray *languages = [defaults objectForKey:@"AppleLanguages"];

我猜測，那地方違約項越來越設爲只是一個字符串或類似的，而不是一個數組 - 檢查你是否在你的應用程序的任何地方引用該字符串。

非常感謝:)我在AppleLanguages中插入了這個值 - [defaults setObject：[localeList objectForKey：languageChoosen] forKey：@「AppleLanguages」];這造成了一切麻煩。 – Pria
