循环[[String：Any]]

Question

用

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

我得到了

[["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]]

如何循环使用此值来获取每个id和title的值？

Answer 1

使用posts对for-loop进行迭代，并确保您的值为guard。

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