问题 I've tried a few solutions so far but I'm not sure if there is a "right" way. I'm working on a todo list with a snooze function. Each task has a "wake from snooze" time when I need to run a function to move it into a different list. I've tried looping through each task and moving it when viewWillAppear and/or viewDidAppear runs. This generally works but seems to misfire occasionally and wouldn't happen while the app is running and the user isn't switching views. I've tried using the Timer()

问题 I would like to access my Realm from an iOS extension however the realm path is unavailable when using the Realm Mobile Platform. I've received advice from realm to hold a cloned copy and keep it in sync. How can that be achieved? ...and is it considered a "clean" solution? (there could be multiple realms) 回答1: You should just open the synced Realm from your extension by creating a Realm configuration with a proper sync configuration (specifying user and remote Realm URL), like usual. This is

问题 Is it impossible to get Realm from the server? I tried this, but it doesn't work. var url = "http://address/default.realm" var rlm = RLMRealm(path: url) Error message says 'No such file or directory' . 回答1: What you're trying isn't supported in this way.

If you want to sync data between the device and your server or

问题 I have iOS project integrated with RMP, so how I can get size of storage from Realm Object Server? 回答1: It is currently not possible to query the server for the size usage of a specific Realm file. This is an API that will (most probably) come at a later date. As a reminder, the Realm Object Server needs to keep the entirety of the history, in order to allow old joiners to merge and get updated to the latest version. 来源： https://stackoverflow.com/questions/40232169/size-of-storage-on-realm

When adding objects to Realm, things are file. But when removing objects, they get removed from the DB, but the file size is still large. If I open the realm file in TextEdit, I can see raw text of old records. Why aren't they getting fully deleted? Take a look at this screenshot. Zero files in the Realm DB, but the file size is 23

问题 I'm having a similar problem as the poster in this thread: Unable to delete an object in a realm database I have an array of RLMObject subclasses created from a search on a queue called 'syncQueue'. It's a bunch of Diagnostic objects that need to be sent up to the server. These objects are packaged up and sent up to the server using the Google Client Library for iOS. Once the library returns that the objects have been successfully uploaded, I want to delete them out of Realm. I grab some
