我有以下JSON结构,我尝试使用SwiftyJSON进行解析,但我无法解决如何遍历"部分"节点。我目前的代码返回每个部分的第一节节点,但我无法访问"第1b节/第2b节"元件。
{
"category": [{
"categoryId": 1,
"categoryHeader": "Category 1",
"sections": [{
"section": "Section 1a title",
"body": "Section 1a body"
}, {
"section": "Section 1b title",
"body": "Section 1b body"
}]
}, {
"categoryId": 2,
"categoryHeader": "Category 2",
"sections": [{
"section": "Section 2a title",
"body": "Section 2a body"
},{
"section": "Section 2a title",
"body": "Section 2b body"
}]
}]
}
我的代码是:
let path: String = NSBundle.mainBundle().pathForResource("jsonFile", ofType: "json") as String!
let data = NSData(contentsOfFile: path) as NSData!
var objects = [[String: String]]()
let json = JSON(data: data)
func parseJSON(json: JSON) {
for category in json["category"].arrayValue {
let categoryHeader = category["categoryHeader"].stringValue
let section = category["sections"][0]["section"].stringValue
let sectionBody = category["sections"][0]["body"].stringValue
let obj = ["categoryHeader": categoryHeader, "section": section, "body": sectionBody] //, "body": body, "title": sigs]
objects.append(obj)
}
tableView.reloadData()
}
我知道我需要遍历部分部分以检索所有值,但我无法解决问题。
修改 尝试使用以下操作允许我访问所有节节点;然后是' categoryHeader'输出' x'时间取决于有多少部分:
func parseJSON(json: JSON) {
for category in json["category"].arrayValue {
let categoryHeader = category["categoryHeader"].stringValue
for section in category["sections"].arrayValue {
let sectionName = section["section"].stringValue
let body = section["body"].stringValue
let obj = ["categoryHeader": categoryHeader, "section": sectionName, "body": body]
objects.append(obj)
}
}
}
答案 0 :(得分:0)
将:
for section in category["sections"].arrayValue {
let sectionName = section["section"].stringValue
let body = section["body"].stringValue
}
工作?

这样做的一种方式可能就是这样。
编辑:我在播放场地中使用此代码。
var objects = [[String: String]]()
func parseJSON(json: JSON) {
let jsonResults = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as! NSDictionary
let json = JSON.self(jsonResults)
// let json = JSON(data: data) // moved this line
let count: Int? = json.dictionary?.count
let ct = 0
if ct < count {
for index in 0...count!-1 {
for category in json["category"].arrayValue {
let categoryHeader = category["categoryHeader"].stringValue
let section = category["sections"][0]["section"].stringValue
let sectionBody = category["sections"][0]["body"].stringValue
let obj = ["categoryHeader": categoryHeader, "section": section, "body": sectionBody] //, "body": body, "title": sigs]
objects.append(obj)
}
}
tableView.reloadData()
}
