我需要使用之前选择的一组用户来测试我的应用程序的一些功能。

我在哪里创建了一个受众user_id exactly matches 123456。123456是我自己的身份证。

在远程配置中，我创建了一个匹配上面受众中的用户的条件。

然后我在远程配置中创建了一个名为的参数，feature_available并为条件设置了一个返回值true。默认值为false。

在我的应用程序中，我设置了 Firebase：

    FIRApp.configure()

    let remoteConfig = FIRRemoteConfig.remoteConfig()
    if let remoteConfigSettings = FIRRemoteConfigSettings(developerModeEnabled: false) {
        remoteConfig.configSettings = remoteConfigSettings
    }
    remoteConfig.setDefaultsFromPlistFileName("FirebaseRemoteConfigDefaults")

并设置用户 ID：

    FIRAnalytics.setUserID("123456")

然后我从 Firebase 获取：

    var expirationDuration: Double
    // If in developer mode cacheExpiration is set to 0 so each fetch will retrieve values from the server.
    expirationDuration = remoteConfig.configSettings.isDeveloperModeEnabled ? 0 : 3600

    remoteConfig.fetch(withExpirationDuration: TimeInterval(expirationDuration)) { (status, error) -> Void in
        if status == .success {
            remoteConfig.activateFetched()
        } else {
            assertionFailure("Firebase config not fetched. Error \(error!.localizedDescription)")
        }
    }

我做的最后一件事是从 Firebase 获取值并检查我是否启用了该功能：

    let featureIsAvailable = remoteConfig["feature_available"].boolValue
    if featureIsAvailable { ... }

问题是每次从 Firebase 返回的值都是这样false，我无法让它返回与我创建的 Audience 匹配的正确值。我还尝试设置用户属性而不是使用setUserID()并得到相同的结果。有什么建议么？

我向 Firebase 团队发送了一封电子邮件请求支持，他们告诉我问题是使用 Swift 的 Xcode 8（.0 和 .1）中的一个错误。更新到今天发布的最新版本 8.2，修复了该问题。

我之前遇到过类似的问题，有时可能需要一段时间才能完成提取。配置成功修复后，需要检查该功能是否可用。希望这样的事情也适合你：

var featureIsAvailable : Bool?

override func viewDidLoad() {
    super.viewDidLoad()

    configureRemoteConfig()
    fetchConfig()      
}

func configureRemoteConfig() {
    remoteConfig = FIRRemoteConfig.remoteConfig()
    // Create Remote Config Setting to enable developer mode.
    // Fetching configs from the server is normally limited to 5 requests per hour.
    // Enabling developer mode allows many more requests to be made per hour, so developers
    // can test different config values during development.
    let remoteConfigSettings = FIRRemoteConfigSettings(developerModeEnabled: true)
    remoteConfig.configSettings = remoteConfigSettings!
    remoteConfig.setDefaultsFromPlistFileName("RemoteConfigDefaults")
}

func fetchConfig() {
    var expirationDuration: Double = 3600
    // If in developer mode cacheExpiration is set to 0 so each fetch will retrieve values from
    // the server.
    if (self.remoteConfig.configSettings.isDeveloperModeEnabled) {
        expirationDuration = 0
    }

    // cacheExpirationSeconds is set to cacheExpiration here, indicating that any previously
    // fetched and cached config would be considered expired because it would have been fetched
    // more than cacheExpiration seconds ago. Thus the next fetch would go to the server unless
    // throttling is in progress. The default expiration duration is 43200 (12 hours).
    remoteConfig.fetch(withExpirationDuration: expirationDuration) { (status, error) in
        if (status == .success) {
            print("Config fetched!")
            self.remoteConfig.activateFetched()

            let featureIsAvailable = self.remoteConfig["feature_available"]

            if (featureIsAvailable.source != .static) {
                self.featureIsAvailable = featureIsAvailable.boolValue
                print("should the feature be available?", featureIsAvailable!)
            }
        } else {
            print("Config not fetched")
            print("Error \(error)")
        }
        self.checkIfFeatureIsAvailable()
    }
}

func checkIfFeatureIsAvailable() {
    if featureIsAvailable == false {
        // Don't show new feature
    } else {
        // Show new feature
    }
}
