循环 [[String: Any]]

Question

与

let posts = json["posts"] as? [[String: Any]] ?? []
print(posts)

我明白了

[["id": 1, "title": title 1], ["id": 2, "title": title 2], ["id": 3, "title": title 3], ["id": 4, "title": title 4], ["id": 5, "title": title 5]]

如何循环获取每个id 和title 的值？

Answer 1

使用for-loop 遍历posts，并确保您拥有guard 的值。

for post in posts{
    guard let id = post["id"] as? Int,
          let title = post["title"] as? String else { continue }
}
