解析Swift 3中的JSON数组
问题描述:
我试图解析JSON文件以在Swift 3中的表格视图中显示而不使用外部框架,但是我在Swift中的知识还不够。我看了其他问题,但没有为我工作。问题是在我的JSON中有几个嵌套数组。 这里是例如JSON文件:解析Swift 3中的JSON数组
"guides" : [
{
"name" : "First Guide",

{
"title" : "Controls",

},
{
"value" : "Sensitivity: Changes the sensitivity of the camera when turning.",
"type" : "text"
},
{
"value" : "Invert Y-Axis: Toggles inversion of camera when looking up/down.",
"type" : "text"

我如何获取数据解析成斯威夫特阵列和用它来显示UITableView控制器。在这个JSON中有几个“指南”,我需要能够在当时只显示其中的一个。 帮助将不胜感激。先谢谢你。

尝试使用以下代码:
let jsonString = "[\"a\",\"b\"]"
let jsonData = jsonString.data(using: .utf8)! as Data
do {
let dataJson = try JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)
print(dataJson)
}
catch {
print("error getting xml string: \(error)")
}
