You may prefer MDQueryMBS class from our plugins. NSMetadataQueryMBS exists as it supports iCloud search.
NSMetadataQuery objects provide metadata query results in several ways:
- As individual attribute values for requested attributes.
- As value lists that contain the distinct values for given attributes in the query results.
- A result array proxy, containing all the query results. This is suitable for use with Cocoa bindings.
- As a hierarchical collection of results, grouping together items with the same values for specified grouping attributes. This is also suitable for use with Cocoa bindings.
Queries have two phases: the initial gathering phase that collects all currently matching results and a second live-update phase.
By default the receiver has no limitation on its search scope. Use setSearchScopes to customize.
By default, notification of updated results occurs at 1.0 seconds. Use setNotificationBatchingInterval to customize.
You must set a predicate with the setPredicate method before starting a query.
