如何将RealmSwift List转换为结果？ [英] how to convert RealmSwift List to Results?

问题描述

我使用Realm List / Results 作为 UITableView 的数据源。在某些时候，我为它分配一个列表。喜欢：

I am using a Realm List/Results as my dataSource for a UITableView. At some point I assign a list to it. like:

var dataSource:List<SomeObject>! // Or >> Results<SomeObject>!
let aRealmObject =  realm.objectForPrimaryKey(SomeObject.self, key: objectId) 
dataSource = aRealmObject.someList // dataSource should be List

然后我在此列表上有一个过滤器如果用户更改过滤日期，我会这样：

Then I have a filter on this list If the user changed the filter dates, I do like this:

dataSource = dataSource.filter("FILTER THE DATES",newDates) // dataSource should be Results

但是上面的行会导致错误，因为过滤器的返回类型是结果对象和 aRealmObject.someList 是一个列表。

But the line above causes an error as the return type of filter is a Results object and aRealmObject.someList is a List.

处理这种情况的最佳方法是什么？

What is the best way to deal with this situation?

• 将dataSource设为列表并转换结果对象列表？怎么??


• 将dataSource作为结果并将 List 转换为结果？怎么样??


• 或者你可能有更好的方法，请与我分享。

• make dataSource as a List and convert the Results object to List? How??
• make dataSource as a Results and convert the List to Results? How??
• Or may be you have a better way of doing it, Please share it with me.

谢谢，

推荐答案

列表和结果（以及 LinkingObjects ）可以转换为 AnyRealmCollection 类型。我认为这可能是标准化所有Realm的数组类型类型的最佳方法：

Both List and Results (as well as LinkingObjects) can be converted into an AnyRealmCollection type. I think this is probably the best way to standardize all of Realm's array-type types:

var dataSource:AnyRealmCollection!
let aRealmObject = realm.objectForPrimaryKey(SomeObject.self, key: objectId) 
dataSource = AnyRealmCollection(aRealmObject.someList)
