问题描述
我已经创建了生成JSON的API，该JSON看起来像这样
I have created API which generate JSON, that JSON looks like this
[
{
"id": 105,
"date": "2018-09-06T22:37:57",
"date_gmt": "2018-09-06T17:07:57",
"guid": {
"rendered": "http://wh2.6ae.myftpupload.com/?p=105"
},
"modified": "2018-09-06T22:37:57",
"modified_gmt": "2018-09-06T17:07:57",
"slug": "video-post-20",
"status": "publish",
"type": "post",

"upload_video": false
},
"_links": {
"self": [
{

}
],

}
],

],

{

}
],
"predecessor-version": [
{
"id": 111,
"href": "http://wh2.6ae.myftpupload.com/wp-json/wp/v2/posts/105/revisions/111"
}
],
"wp:attachment": [
{
"href": "http://wh2.6ae.myftpupload.com/wp-json/wp/v2/media?parent=105"
}
],
"wp:term": [
{
"taxonomy": "category",
"embeddable": true,
"href": "http://wh2.6ae.myftpupload.com/wp-json/wp/v2/categories?post=105"
},
{
"taxonomy": "post_tag",
"embeddable": true,
"href": "http://wh2.6ae.myftpupload.com/wp-json/wp/v2/tags?post=105"
}
],
"curies": [
{
"name": "wp",
"href": "https://api.w.org/{rel}",
"templated": true
}
]
}
}
]
我为此创建了类
-
邮政课
Post Class
import Foundation
import RealmSwift
class Post : Object{
@objc dynamic var id = 0
@objc dynamic var date = ""
@objc dynamic var date_gmt = ""
@objc dynamic var modified = ""
@objc dynamic var modified_gmt = ""
@objc dynamic var slug = ""
@objc dynamic var status = ""
@objc dynamic var type = ""
@objc dynamic var link = ""
@objc dynamic var format = ""
@objc dynamic var fimg_url : Bool = false
@objc dynamic var title : Rendered? = nil
@objc dynamic var excerpt : Rendered? = nil
@objc dynamic var content : Rendered? = nil
@objc dynamic var acf : Acf? = nil
override static func primaryKey() -> String? {
return "id"
}
}
ImageCarousel
ImageCarousel
import Foundation
import RealmSwift
class ImagesCarousel: Object {
@objc dynamic var ID = 0
@objc dynamic var id = 0
@objc dynamic var title = ""
@objc dynamic var filename = ""
@objc dynamic var filesize = 0
@objc dynamic var url = ""
@objc dynamic var date = ""
@objc dynamic var modified = ""
@objc dynamic var mime_type = ""
@objc dynamic var type = ""
@objc dynamic var subtype = ""
@objc dynamic var width = 0
@objc dynamic var height = 0
@objc dynamic var sizes : Sizes? = nil
override static func primaryKey() -> String? {
return "ID"
}
}
Acf
Acf
import Foundation
import RealmSwift
class Acf: Object {
private RealmList<ImagesCarousel> imagesCarousel;
var imagesCarousel = List<ImagesCarousel>()
@objc dynamic var youtube_video_id = ""
}
已渲染
Rendered
import Foundation
import RealmSwift
class Rendered: Object {
@objc dynamic var rendered = ""
}
大小
Size
import Foundation
import RealmSwift
import Realm
class Sizes: Object {
@objc dynamic var large = ""
}
我的快捷代码
if let allData = response.result.value as? NSArray{
let realm = try! Realm()
for selectedData in allData{
print(selectedData)
let jsonData = try? JSONSerialization.data(withJSONObject: selectedData, options: [])
let myString = String(data: jsonData!, encoding: String.Encoding.utf8)
print(myString)
// Insert from Data containing JSON
try! realm.write {
let json = try! JSONSerialization.jsonObject(with: data!, options: [])
realm.create(Post.self, value: json, update: true)
//realm.add(testData.self, value: json, update: true)
}
}
}
这是给我这种类型的错误
Which is giving me this type of error
[__NSCFDictionary longLongValue]: unrecognized selector sent to
instance 0x7fdcc8785820 2016-07-06 10:25:30.090
mydrawing[9436:2732447] *** Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[__NSCFDictionary
longLongValue]: unrecognized selector sent to instance 0x7fdcc8785820'
但是如果我从json数据中删除[和]，则可以正常工作
but if I remove [ and ] from json data then it's working fine
let data = "{\"id\":1088,\"date\":\"2018-09-06T22:37:57\",\"date_gmt\":\"2018-09-06T17:07:57\",\"guid\":{\"rendered\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/?p=105\"},\"modified\":\"2018-09-06T22:37:57\",\"modified_gmt\":\"2018-09-06T17:07:57\",\"slug\":\"video-post-20\",\"status\":\"publish\",\"type\":\"post\",\"link\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/video-post-20\\/\",\"title\":{\"rendered\":\"Video post – 20\"},\"content\":{\"rendered\":\"\",\"protected\":false},\"excerpt\":{\"rendered\":\"\",\"protected\":false},\"author\":1,\"featured_media\":0,\"comment_status\":\"open\",\"ping_status\":\"open\",\"sticky\":false,\"template\":\"\",\"format\":\"video\",\"meta\":\"m\",\"categories\":5,\"tags\":\"m\",\"fimg_url\":false,\"_links\":{\"self\":{\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/posts\\/105\"},\"collection\":{\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/posts\"},\"about\":{\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/types\\/post\"},\"author\":{\"embeddable\":true,\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/users\\/1\"},\"replies\":{\"embeddable\":true,\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/comments?post=105\"},\"version-history\":{\"count\":1,\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/posts\\/105\\/revisions\"},\"predecessor-version\":{\"id\":111,\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/posts\\/105\\/revisions\\/111\"},\"wp:attachment\":{\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/media?parent=105\"},\"wp:term\":{\"taxonomy\":\"category\",\"embeddable\":true,\"href\":\"http:\\/\\/wh2.6ae.myftpupload.com\\/wp-json\\/wp\\/v2\\/categories?post=105\"},\"curies\":{\"name\":\"wp\",\"href\":\"https:\\/\\/api.w.org\\/{rel}\",\"templated\":true}}}".data(using: .utf8)
let realm = try! Realm()
// Insert from Data containing JSON
try! realm.write {
let json = try! JSONSerialization.jsonObject(with: data!, options: [])
realm.create(Post.self, value: json, update: true)
}
- 我引用了此链接
- 最后，我认为我无法在领域中添加数组，也没有找到任何官方方法.
推荐答案
您的代码只是尝试替换此行
You'r code worked just try to replace this line
try! realm.write {
let json = try! JSONSerialization.jsonObject(with: data!, options: [])
realm.create(Post.self, value: json, update: true)
//realm.add(testData.self, value: json, update: true)
}
对此
try! realm.write {
let json = try! JSONSerialization.jsonObject(with: jsonData!, options: [])
realm.create(Post.self, value: json, update: true)
//realm.add(testData.self, value: json, update: true)
}
结果
