Swift

// Delete the German model if it's on the device.

Swift

// Download the French model.
let frModel = TranslateRemoteModel.translateRemoteModel(language: .fr)

// Keep a reference to the download progress so you can check that the model
// is available before you use it.
progress = ModelManager.modelManager().download(

अगर आपको NotificationCenter की मदद से डाउनलोड की स्थिति चाहिए, तो firebaseMLModelDownloadDidSucceed और firebaseMLModelDownloadDidFail के लिए ऑब्ज़र्वर रजिस्टर करें. ऑब्ज़र्वर ब्लॉक में, self के लिए कमज़ोर रेफ़रंस का इस्तेमाल करना न भूलें. ऐसा इसलिए, क्योंकि डाउनलोड होने में कुछ समय लग सकता है. साथ ही, डाउनलोड पूरा होने तक, ओरिजनल ऑब्जेक्ट को खाली किया जा सकता है. उदाहरण के लिए:

NotificationCenter.default.addObserver(
    forName: .firebaseMLModelDownloadDidSucceed,
    object: nil,
    queue: nil
) { [weak self] notification in
    guard let strongSelf = self,
        let userInfo = notification.userInfo,
        let model = userInfo[ModelDownloadUserInfoKey.remoteModel.rawValue]
            as? TranslateRemoteModel,
        model == frModel
        else { return }
    // The model was downloaded and is available on the device
}

NotificationCenter.default.addObserver(
    forName: .firebaseMLModelDownloadDidFail,
    object: nil,
    queue: nil
) { [weak self] notification in
    guard let strongSelf = self,
        let userInfo = notification.userInfo,
        let model = userInfo[ModelDownloadUserInfoKey.remoteModel.rawValue]
            as? TranslateRemoteModel
        else { return }
    let error = userInfo[ModelDownloadUserInfoKey.error.rawValue]
    // ...
}

Objective-C

// Download the French model.
FIRModelDownloadConditions *conditions =
    [[FIRModelDownloadConditions alloc] initWithAllowsCellularAccess:NO
                                         allowsBackgroundDownloading:YES];
FIRTranslateRemoteModel *frModel =
    [FIRTranslateRemoteModel translateRemoteModelWithLanguage:FIRTranslateLanguageFR];

// Keep a reference to the download progress so you can check that the model
// is available before you use it.
self.downloadProgress = [[FIRModelManager modelManager] downloadModel:frModel
                                                           conditions:conditions];

अगर आपको NSNotificationCenter की मदद से डाउनलोड की स्थिति चाहिए, तो FIRModelDownloadDidSucceedNotification और FIRModelDownloadDidFailNotification के लिए ऑब्ज़र्वर रजिस्टर करें. ऑब्ज़र्वर ब्लॉक में self के लिए कमज़ोर रेफ़रंस का इस्तेमाल करना न भूलें. ऐसा इसलिए, क्योंकि डाउनलोड होने में कुछ समय लग सकता है. साथ ही, डाउनलोड पूरा होने से पहले, ऑरिजिन ऑब्जेक्ट को खाली किया जा सकता है.
