ios - 访问字典数组的嵌套数组

Question

我想在 TableView 上显示“描述”的值，但无法访问“描述”。每次我都会循环播放。示例

for i in item { 
   let result = i["description"]     
}

它返回类型“Any”没有下标成员

[[["description": "Meeting", "comments": "", "projectId": 6, "hours": 0.0, "id": 52, "projectName": "A-DA Internal"], ["description": "Others", "comments": "", "projectId": 6, "hours": 0.0, "id": 53, "projectName": "A-DA Internal"], ["description": "3.1 Project Planning", "comments": "", "projectId": 5, "hours": 0.0, "id": 28, "projectName": "STARWorks ESS"], ["description": "4.1 Analysis & Design", "comments": "", "projectId": 5, "hours": 0.0, "id": 32, "projectName": "STARWorks ESS"], ["description": "4.3 Bug fixes", "comments": "", "projectId": 5, "hours": 0.0, "id": 34, "projectName": "STARWorks ESS"]]]

Answer 1

从您上面发布的响应来看，类型似乎是[[[String : Any]]]。因此，要到达 [String: Any] 部分，您必须深入两个级别。

//let say
let result: [[[String: Any]]] = THE RESPONSE YOU POSTED..

let item = result.flatmap {$0} //this will convert to [[String: Any]]

 //After that your loop will work as expected

 for i in item {
        debugPrint(i["description"])
 }
