问题 Beginner programmer here. I am trying to show two different color dots if there is a negative AND a positive transaction for that date. Here is my code. It only shows one dot. func calendar(_ calendar: FSCalendar, numberOfEventsFor date: Date) -> Int { let incomeTransaction = realm.objects(Transaction.self).filter(positiveTransactionPredicate(date: date)) let expenseTransaction = realm.objects(Transaction.self).filter(negativeTransactionPredicate(date: date)) for _ in incomeTransaction {

问题 I have an app written in ObjC. I've chosen Realm as my DataBase. I would like to start migrating some parts of my app to Swift. When getting to Realm I get confused. There are two pods . From what I understood from the docs, RealmSwift is for pure Swift projects, right? But, is it possible to migrate model classes to Swift without the RealmSwift pod ? 回答1: As I understand it, Realm Swift isn't exclusive for pure Swift projects, but if you do use it in an iOS app, you can't make any calls to

问题 I use Retrofit, Gson and Realm in my project. I have this class Example that need to be Serializable . Without Realm I'd write it like that : public class Example implements Serializable { @SerializationName("users") private List<String> users //... getters and setters } Realm comes into play and Example becomes (note that getters and setters are this way for compatibility reasons) : public class Example extends RealmObject implement Serializable { @SerializedName("users") private RealmList

问题 I am making a React native app, with native services to scan for devices nearby. It works fine when the app is in foreground, but when the app is killed and the service detects a device, it wakes up the React Native part of app by headless JS and makes an API call using redux action, but it cannot store the data received from API call in reducer data. I can't user AsyncStorage as the data is big and a JSON. How do I persist this data so that when the app is started, the users can see the data

问题 Here is an example. class Person: Object { dynamic var id dynamic var name } // does this work? let sortedPeople = realm.objects(Person).sorted("id") let Dave = realm.objects(Person).filter("id=5") // at what index does Dave reside in sortedPeople? The reason I need to find out about this is coz I have a UITableView that is set to the sortedPeople, but I need to store the last visible row viewed. The sortedPeople array changes frequently. So, if I can find out the index in the sortedPeople of
