如何在Swift中将Realm对象转换为JSON？

设法在这里找到答案：

我可以在Realm forSwift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}}

Xpre 7和Swift 2的更新：

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Xpre 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}}
