let src = json as NSDictionary

生效了,
写入失败,
为什么?
当然不是代码的问题,是数据的问题
数据长这样
json:
{
"message" : "","code": 200,"state": null,"data": {"author":"",
"next_id" : 409,
"title" : "2 金木水火土",
"prev_id" : 405,
"list" : [
{
"string" : "识字",
"type" : 0
},
{
"string" : "一:一个 一群",
"type" : 1,
"pronounce" : "yī"
}
],
"nodes" : {
"wav_lengths" : [
0,
4.0049999999999999,
8.2509999999999994
],
"node" : [
{
"index" : 0,
"title" : "识字"
}
]
},
"audio" : "http://ss-cn.aliyuncs.com/chinese_audio%2F%E9%83%A8%E7%BC%96%E7%89%88%E8%AF%AD%E6%96%87%E5%85%AD%E4%B8%89%E5%88%B6%2F%E4%B8%80%E5%B9%B4%E7%BA%A7%E4%B8%8A%E5%86%8C%2Faudio%2F%E8%AF%86%E5%AD%972.wav?OSSAccessKeyId=LTAIQ8Lif1HHVkXd&Expires=1606364958&Signature=XC%2Fm%2BLKZ30b%2FVYCsXrwCaNj6nZI%3D"
}
}
数据是字典,但不合乎 plist 的标准
{
"string" : "识字",
"type" : 0
},
{
"string" : "一:一个 一群",
"type" : 1,
"pronounce" : "yī"
}
list 外面是数组,数组装字典,
一个字典三个键,一个字典两个键,
所以呵呵
批改代码:
let resp = try Base.decoder.decode(GeneralSingle<P_intelligence>.self, from: data)
var newPlistModel = resp
var i = 0
let count = resp.data.list.count
while i < count{if resp.data.list[i].pronounce == nil{newPlistModel.data.list[i].pronounce = "hehe"
}
i += 1
}
let json = newPlistModel.data.dictionary
let src = json as NSDictionary
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let path = documentsURL.appendingPathComponent("one.plist")
let result = src.write(to: path, atomically: false)
print(result, path)
对应的模型:
struct P_intelligence: Codable {
let listen: String
let see: Node_intelligence
var list: [Moron]
let title: String
let pre: Int
let next: Int
let author: String?
private enum CodingKeys : String, CodingKey {
case listen = "audio", see = "nodes"
case list, title, pre = "prev_id"
case next = "next_id", author
}
var dictionary: [String: Any] {return (try? JSONSerialization.jsonObject(with: JSONEncoder().encode(self))) as? [String: Any] ?? [:]
}
}
struct Moron: Codable {
let string: String
let type: Int
var pronounce: String?
}
// ......
