如何在Swift 3中使用循环打印JSON值?

本文介绍了如何在Swift 3中使用循环打印JSON值?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我得到了这个JSON:

{ cover = { id = 1; }; description = "Test" place = { id = 11; location = { city = Wheatley; }; name = "Wheatley Provincial Park"; }; }, { cover = { id = 2; }; description = "Cool" place = { id = 22; location = { city = Wheatley; }; name = "Wheatley Provincial Park"; }; }

这是我的代码:

if let fbData = result as? [String : Any] { print(fbData) for events in fbData { print (events["name"] as! String) //this displays an error //Type (Key: String, value: Any) has subscript members }

}

但是我不知道如何遍历它们

我已经尝试过这些解决方案，但是它们从未起作用:

在Swift 3中进行JSON解析

在Swift 3中正确解析JSON

使用Swift 3解析JSON

解决方案

if let array = result as? [String : AnyObject]{ if let fbData = array["data"] as? [[String : AnyObject]] { print(fbData) for event in fbData { print (event["name"] as! String) } } }

result是Any类型

将其发布到字典中-[String : AnyObject]

提取data并转换为字典数组-[[String : AnyObject]].

I got this JSON:

{ cover = { id = 1; }; description = "Test" place = { id = 11; location = { city = Wheatley; }; name = "Wheatley Provincial Park"; }; }, { cover = { id = 2; }; description = "Cool" place = { id = 22; location = { city = Wheatley; }; name = "Wheatley Provincial Park"; }; }

This is my code:

if let fbData = result as? [String : Any] { print(fbData) for events in fbData { print (events["name"] as! String) //this displays an error //Type (Key: String, value: Any) has subscript members }

}

But I don't know how to loop through them

I already tried these solutions but they never worked:

JSON Parsing in Swift 3

Correctly Parsing JSON in Swift 3

Parsing JSON using Swift 3

解决方案

if let array = result as? [String : AnyObject]{ if let fbData = array["data"] as? [[String : AnyObject]] { print(fbData) for event in fbData { print (event["name"] as! String) } } }

result is of Any type

Cast it into Dictionary - [String : AnyObject]

Extract data and cast to Array of Dictionaries - [[String : AnyObject]].
