I am querying over a RLMArray with objectsWhere and i get a RLMResults, but i need a RLMArray with the results a this point in my code.
private var data: RLMArray?
self.data = self.currentSubcategory!.datasheets // is a RLMArray
self.data = self.data!.objectsWhere("is_favourite = 1")
RLMArray has been split into two classes: RLMArray and
RLMResults. RLMArray is now used only for to-many properties on
RLMObject classes, while RLMResults is used for all of the
querying and sorting methods. This was done to reflect that the two
actually had fairly different APIs (for example, RLMResults does not
have addObject:), and they’re expected to diverge further as we add
change notifications for queries.
The migration for this should be as simple as replacing RLMArray
with RLMResults in all of the places that the compiler complains
To go with this, arraySortedByProperty:ascending: has been renamed
to sortedResultsUsingProperty:ascending:, and addObjectsFromArray:
has been renamed to addObjects: to reflect the fact that you can
pass any enumerable object to it (such as NSArray, RLMArray, or
RLMResults).
Hope that's enough
You need to add objects from RLMResult to RLMArray...
@implementation RLMResults (RLMArrayConversion)
- (RLMArray *)toArray {
RLMArray * array = [[RLMArray alloc] initWithObjectClassName:self.objectClassName];
[array addObjects:self];
11.8k989141
let datasheets = self.currentSubcategory!.datasheets!.objectsWhere("is_favourite = 1")
let objects = Array(datasheets.generate())
self.data!.removeAllObjects()
self.data!.addObjects(objects)
Creating the array of the results is required because the self.data!.removeAllObjects() line will also clear datasheets, since RLMResults are live-updating as you make changes to the source.
