At the top of your Swift source files if you have anyuse import Realm. So instead, you should declare your RLMArray properties with the following syntax: However, be sure to comply with App Store guidelines, keeping your app under MB. Please browse our tvOS examples for sample tvOS apps demonstrating how to use Realm as either an offline cache or with preloaded data.
Using Realm with background app refresh On iOS 8 and above, files inside apps are automatically encrypted using NSFileProtection whenever the device is locked. If your app attempts to do any work involving Realm while the device is locked and the NSFileProtection attributes of your Realm files are set to encrypt them which is the case by defaultan open failed: Operation not permitted exception will be thrown.
In order to handle this, it is necessary to ensure that the file protection attributes applied to both the Realm file itself and its auxiliary files is downgraded to a less strict one that allows file access even when the device is locked, such as NSFileProtectionCompleteUntilFirstUserAuthentication.
Since the auxiliary files can sometimes be lazily created and deleted mid-operation, we recommend that you apply the file protection attributes to the parent folder containing these Realm files. This will ensure the attribute is properly applied to all of the relevant Realm files, regardless of their creation time.
Creating and customizing a configuration value allows you to customize, among other aspects: For example, suppose you have an application where users have to log in to your web backend, and you want to support quickly switching between accounts.
You could give each account its own Realm file that will be used as the default Realm by doing the following: If a custom URL is used to initialize a Realm, it must describe a location with write permissions.
The default Realm You may have noticed so far that we have initialized access to our realm variable by calling [RLMRealm defaultRealm]. That method returns an RLMRealm object that maps to a file named default.
See our documentation on error handling for details. All sync related documentation has been moved to our platform documentation In-memory Realms By setting the inMemoryIdentifier rather than the fileURL on your RLMRealmConfiguration, you can create a Realm that runs entirely in memory without being persisted to disk.
This is a useful option if you need flexible data access without the overhead of disk persistence. In-memory Realms create several files in a temporary directory for coordinating things like cross-process notifications. No data is actually written to the files unless the operating system needs to swap to disk due to memory pressure.
When all in-memory Realm instances with a particular identifier go out of scope with no references, all data in that Realm is deleted.
This is not necessary for on-disk Realms. In practice, this can only happen the first time a Realm instance is created on a given thread. Subsequent accesses to a Realm from the same thread will reuse a cached instance and will always succeed.
To handle errors when first accessing a Realm on a given thread, provide an NSError pointer to the error parameter: When reporting Realm issuesplease be sure to include these auxiliary files along with your main.
First, populate the Realm. You should use the same data model as your final, shipping app to create a Realm and populate it with the data you wish to bundle with your app. At this point, your bundled Realm file will be accessible to your app.
You can refer to our migration sample app for an example of how to use a bundled Realm file. Class subsets In some scenarios you may wish to limit which classes can be stored in a specific Realm. For example, if you have two teams working on different components of your application which both use Realm internally, you may not want to have to coordinate migrations between them.symfonyでのメール送信。 MacbookAirにあらかじめインストー.
