如何在Swift中将Realm对象转换为JSON? [英] How can I convert a Realm object to JSON in Swift?
本文介绍了如何在Swift中将Realm对象转换为JSON?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我声明了两个Realm表:
I have two Realm tables declared:
class Task: Object {
dynamic var taskID: String = ""
let taskAssignedTo = List<Contacts>()
}
class Contacts: Object {
dynamic var contactEmail: String = ""
dynamic var contactName: String = ""
}
最终目标是将Task Realm对象转换为JSON.我在想的方法是:
Final goal is to convert the Task Realm object into JSON. The method I'm thinking of is:
使用类中的方法将对象转换为字典
Convert the object to a dictionary using a method within the class
func taskToDictionary() -> [String: AnyObject] {
return [
"taskID" : self.taskID,
"taskAssignedTo" : self.taskAssignedTo._rlmArray.count //Not sure how to get the array
]
}
使用SwiftyJSON将结果字典转换为JSON
Convert the resulting dictionary into JSON with SwiftyJSON
let taskObject = Task()
let newTaskJSON = JSON(taskObject.taskToDictionary())
现在,这可以确定,但是:
Right now, this converts ok, but:
- 是否有更好的方法来做到这一点?
- 如何将RLMArray转换为用于JSON转换的数组?
推荐答案
设法在此处找到答案:
可以我在Realm for Swift中将RealmObject序列化为JSON或NSDictionary吗?
extension Object {
func toDictionary() -> NSDictionary {
let properties = self.objectSchema.properties.map { $0.name }
let dictionary = self.dictionaryWithValuesForKeys(properties)
var mutabledic = NSMutableDictionary()
mutabledic.setValuesForKeysWithDictionary(dictionary)
for prop in self.objectSchema.properties as [Property]! {
// find lists
if let objectClassName = prop.objectClassName {
if let nestedObject = self[prop.name] as? Object {
mutabledic.setValue(nestedObject.toDictionary(), forKey: prop.name)
} else if let nestedListObject = self[prop.name] as? ListBase {
var objects = [AnyObject]()
for index in 0..<nestedListObject._rlmArray.count {
if let object = nestedListObject._rlmArray[index] as? Object {
objects.append(object.toDictionary())
}
}
mutabledic.setObject(objects, forKey: prop.name)
}
}
}
return mutabledic
}
}
更新Xcode 7&斯威夫特2:
extension Object {
func toDictionary() -> NSDictionary {
let properties = self.objectSchema.properties.map { $0.name }
let dictionary = self.dictionaryWithValuesForKeys(properties)
let mutabledic = NSMutableDictionary()
mutabledic.setValuesForKeysWithDictionary(dictionary)
for prop in self.objectSchema.properties as [Property]! {
// find lists
if let nestedObject = self[prop.name] as? Object {
mutabledic.setValue(nestedObject.toDictionary(), forKey: prop.name)
} else if let nestedListObject = self[prop.name] as? ListBase {
var objects = [AnyObject]()
for index in 0..<nestedListObject._rlmArray.count {
let object = nestedListObject._rlmArray[index] as AnyObject
objects.append(object.toDictionary())
}
mutabledic.setObject(objects, forKey: prop.name)
}
}
return mutabledic
}
}
更新到Xcode 8和Swift 3:
extension Object {
func toDictionary() -> NSDictionary {
let properties = self.objectSchema.properties.map { $0.name }
let dictionary = self.dictionaryWithValues(forKeys: properties)
let mutabledic = NSMutableDictionary()
mutabledic.setValuesForKeys(dictionary)
for prop in self.objectSchema.properties as [Property]! {
// find lists
if let nestedObject = self[prop.name] as? Object {
mutabledic.setValue(nestedObject.toDictionary(), forKey: prop.name)
} else if let nestedListObject = self[prop.name] as? ListBase {
var objects = [AnyObject]()
for index in 0..<nestedListObject._rlmArray.count {
let object = nestedListObject._rlmArray[index] as AnyObject
objects.append(object.toDictionary())
}
mutabledic.setObject(objects, forKey: prop.name as NSCopying)
}
}
return mutabledic
}
}
