Looking for the following function: Tap a button to backup the *.sqlite file from the Apps Document Directory up to iCloud at users preference. Tap a button to copy the *.sqlite file down from iCloud to the Apps Document Directory. I have

问题 In react native we have: type MkdirOptions = { NSURLIsExcludedFromBackupKey?: boolean; // iOS only }; What is the equivalent in NativeScript? I need a directory under knownFolders.documents() that will not be backed-up to iCloud. 回答1: Try this, NSURL.URLWithString(path).setResourceValueForKeyError(true, NSURLIsExcludedFromBackupKey); Where path is complete path of your file or folder. 来源： https://stackoverflow.com/questions/58363089/using-nsurlisexcludedfrombackupkey-in-nativescript

问题 I'm trying to get up and running with an NSMetadataQueryDidUpdateNotification on an OS X app, to alert me when a file in my iCloud ubiquity container is updated. I've been doing a lot of research (including reading other Stack answers like this, this, this, and this), but I still don't have it quite right, it seems. I've got a "CloudDocument" object subclassed from NSDocument, which includes this code in the H: @property (nonatomic, strong) NSMetadataQuery *alertQuery; and this is the M file:

问题 I am developing an app with iCloud enabled. While uploading the app to apple I got following error: Invalid Code Signing Entitlements.

问题 I have a bug where my app wont pull icloud inforamtion on the first launch but it does on the subsequent tries. here is my code to load a file from icloud. void DLC::loadFromiCloud(std::string fileName){ NSURL *mUbiqUrl = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil]; if (mUbiqUrl) { std::string fullPath = getLibraryPath_iOS() + fileName; NSString* restorePath = [NSString stringWithUTF8String:(fullPath.c_str())]; NSError *error = nil; NSURL *fileToDownload = [mUbiqUrl

问题 I am trying to implement core data sync using iCloud. However, there is one attribute that I don't want to sync. Is there a proper way to tell iCloud to sync most managed objects and attributes, but not others? 回答1: Right now, Core Data + iCloud does not support this kind of configuration. You may have to split your Data into two Persistent Stores (lokal, cloud). 回答2: One workaround would be to add the things you do not wish to sync to an entity that includes a unique device identifier.

问题 Acording to Apple's Document, The lightweight migration for core data connected with iCloud can be performed automatically. And another documents from Apple says that: If you migrate a persistent store configured with a NSPersistentStoreUbiquitousContentNameKey option to a new model version, the store’s history of changes originating from the current device will also be migrated and then merged with any other devices configured with that new model version. Any changes from stores using the

问题 has anybody managed to get iCloud working on tvOS so far? I am using key-value-storage and it successfully saves everything in iCloud. However, it does not synchronize the data between the iOS-App and the tvOS-App. I am using the same bundle-identifier for both apps. Has anyone experienced the same issue? 回答1: So, it appears that Apple may have an issue here on the tvOS side, because if I follow Apple's instructions on Configuring Common Key-Value Storage for Multiple Apps I can share between
