问题 I am trying to copy one realm object data to another realm object data. Is this possible without having to set each property individually? I am doing the following but the app just stops responding and ends up crashing.

问题 Okay, I'm not very sure how to ask this but I'm going to try. I am using MapStruct to map my incoming network objects to database objects. I use Realm.io as my local datastore.

问题 I have a collection view with Album objects. An Album could be favorited or unfavorited by tapping a button inside of the cell. The buttons image changes depending on if the Album is favorited or not. This part is easy and works.
