为什么我的文本没有被添加到我的标签？

Question

修订后：所以贴在下面的代码是我stuct

struct AnimeJsonStuff: Decodable { 
    let data: [AnimeDataArray] 
} 

struct AnimeLinks: Codable { 
    var selfStr : String? 

    private enum CodingKeys : String, CodingKey { 
     case selfStr  = "self" 
    } 
} 
struct AnimeAttributes: Codable { 
    var createdAt : String? 
    var slug : String? 
    private enum CodingKeys : String, CodingKey { 
     case createdAt  = "createdAt" 
     case slug = "slug" 
    } 
} 
struct AnimeRelationships: Codable { 
    var links : AnimeRelationshipsLinks? 

    private enum CodingKeys : String, CodingKey { 
     case links  = "links" 
    } 
} 

struct AnimeRelationshipsLinks: Codable { 
    var selfStr : String? 
    var related : String? 

    private enum CodingKeys : String, CodingKey { 
     case selfStr  = "self" 
     case related  = "related" 
    } 
} 

struct AnimeDataArray: Codable { 
    let id: String? 
    let type: String? 
    let links: AnimeLinks? 
    let attributes: AnimeAttributes? 
    let relationships: [String: AnimeRelationships]? 

    private enum CodingKeys: String, CodingKey { 
     case id = "id" 
     case type = "type" 
     case links = "links" 
     case attributes = "attributes" 
     case relationships = "relationships" 
    } 
} 

此代码是我的分析数据功能：

func jsonDecoding() { 

    let jsonUrlString = "https://kitsu.io/api/edge/anime" 

    guard let url = URL(string: jsonUrlString) else {return} 
    URLSession.shared.dataTask(with: url) { (data, response, err) in 
     guard let data = data else {return} 
     do { 
      let animeJsonStuff = try JSONDecoder().decode(AnimeJsonStuff.self, from: data) 
      for anime in animeJsonStuff.data { 
       // print(anime.id) 
       // print(anime.type) 
       // print(anime.links?.selfStr) 
       let animeName = anime.attributes?.slug 
       print(animeName) 
       DispatchQueue.main.async { 
        self.nameLabel.text = animeName 
       } 

       for (key, value) in anime.relationships! { 
        // print(key) 
        // print(value.links?.selfStr) 
        // print(value.links?.related) 
       } 
      } 
     } catch let jsonErr { 
      print("Error serializing json", jsonErr) 
     } 
     }.resume() 
} 

这是控制台打印出：

Optional("cowboy-bebop") 
Optional("cowboy-bebop-tengoku-no-tobira") 
Optional("trigun") 
Optional("witch-hunter-robin") 
Optional("beet-the-vandel-buster") 
Optional("eyeshield-21") 
Optional("honey-and-clover") 
Optional("hungry-heart-wild-striker") 
Optional("initial-d-fourth-stage") 
Optional("monster") 
Optional("cowboy-bebop") 
Optional("cowboy-bebop-tengoku-no-tobira") 
Optional("trigun") 
Optional("witch-hunter-robin") 
Optional("beet-the-vandel-buster") 
Optional("eyeshield-21") 
Optional("honey-and-clover") 
Optional("hungry-heart-wild-striker") 
Optional("initial-d-fourth-stage") 
Optional("monster") 
Optional("cowboy-bebop") 
Optional("cowboy-bebop-tengoku-no-tobira") 
Optional("trigun") 
Optional("witch-hunter-robin") 
Optional("beet-the-vandel-buster") 
Optional("eyeshield-21") 
Optional("honey-and-clover") 
Optional("hungry-heart-wild-striker") 
Optional("initial-d-fourth-stage") 
Optional("monster") 

它现在显示文本，但它只显示最后一个可选叫做怪物，而当我有三个单元格时，它不是所有其他的怪物。它只在每个单元格中显示怪物。 应该

第一小区：牛仔bebpop 第二小区：牛仔波普 - 天国 - 没有海桐 第三单元：枪神Trigun 和等

1. 我看不到你在哪里设置变量为post。
2. 把nambeLabel放在Controller的视图层次结构中的位置？

3. 也许你应该设置nameLabel.text在主线程：

   DispatchQueue.main.async { 
       self.nameLabel.attributedText = attributedText 
   }
