Dopo aver caricato i file su Cloud Storage, puoi anche eliminarli.
Eliminare un file
Per eliminare un file, devi prima
creare un riferimento
a quel file. Quindi chiama il metodo deleteWithCompletion: su questo riferimento.
Swift
// Create a reference to the file to deleteletdesertRef=storageRef.child("desert.jpg")do{// Delete the filetryawaitdesertRef.delete()}catch{// ...}
Objective-C
// Create a reference to the file to deleteFIRStorageReference*desertRef=[storageRefchild:@"images/desert.jpg"];// Delete the file[desertRefdeleteWithCompletion:^(NSError*error){if(error!=nil){// Uh-oh, an error occurred!}else{// File deleted successfully}}];
Gestisci gli errori
Esistono diversi motivi per cui potrebbero verificarsi errori durante l'eliminazione dei file,
tra cui l'inesistenza del file o la mancanza di autorizzazione
per eliminare il file specificato. Per ulteriori informazioni sugli errori, consulta la sezione
Gestire gli errori
della documentazione.

You can change your Firebase Security Rules for Cloud Storage to [allow unauthenticated access for specific situations](/docs/storage/security/rules-conditions#public). However, for most situations, we strongly recommend [restricting access and setting up robust security rules](/docs/storage/security/get-started) (especially for production apps). Note that if you use Google App Engine and have a default Cloud Storage bucket with a name format of `*.appspot.com`, you may need to consider [how your security rules impact access to App Engine files](/docs/storage/gcp-integration#security-rules-and-app-engine-files).\n\nDelete a File\n\nTo delete a file, first\n[create a reference](/docs/storage/ios/create-reference)\nto that file. Then call the `deleteWithCompletion:` method on that reference. \n\nSwift \n\n```swift\n// Create a reference to the file to delete\nlet desertRef = storageRef.child(\"desert.jpg\")\n\ndo {\n // Delete the file\n try await desertRef.delete()\n} catch {\n // ...\n}\n \n```\n\nObjective-C \n\n```objective-c\n// Create a reference to the file to delete\nFIRStorageReference *desertRef = [storageRef child:@\"images/desert.jpg\"];\n\n// Delete the file\n[desertRef deleteWithCompletion:^(NSError *error){\n if (error != nil) {\n // Uh-oh, an error occurred!\n } else {\n // File deleted successfully\n }\n}];\n \n```\n| **Note:** Deleted files are typically recoverable for 7 days with [soft delete](https://cloud.google.com/storage/docs/soft-delete), which is enabled by default.\n\nHandle Errors\n\nThere are a number of reasons why errors may occur on file deletes,\nincluding the file not existing, or the user not having permission\nto delete the specified file. More information on errors can be found in the\n[Handle Errors](/docs/storage/ios/handle-errors)\nsection of the docs."]]
