使用swiftjson循环对象
我使用SwiftJSON()在下面的json中循环:使用swiftjson循环对象,json,swift,Json,Swift,我使用SwiftJSON()在下面的json中循环: { "response": { "codes": [ { "id": "abc", "name": "Bob Johnson" }, { "id": "def", "name": "Benson"
{
"response": {
"codes": [
{
"id": "abc",
"name": "Bob Johnson"
},
{
"id": "def",
"name": "Benson"
}
]
}
}
我正在尝试循环通过代码
块。到目前为止,我正在尝试:
let json = JSON(data: getJSON("<json_url>"))
var people = json["response"]["codes"]
let dataArray = nearBy.arrayValue!;
println("Data items count: \(dataArray.count)")
for item: AnyObject in dataArray {
if let userName = item["name"].string{
//Calm down, take it easy, the ".string" property still produces the correct Optional String type with safety
println("Value" + userName)
}
}
如果这两种方法都能奏效,那将是有帮助的
{ "callout":{ "title":"Callout title","image":"http://image","url":"http://callouturl"},"categories":[ { "category":"Category 1","articles":[ { "title":"title 1","image":"image 1","url":"http://url1.com"},{ "title":"title 2","image":"image 2","url":"http://url2.com"}]},{ "category":"Category 2","articles":[ { "title":"title 3","image":"image 3","url":"http://url3.com"},{ "title":"title 4","image":"image 4","url":"http://url4.com"}]}]}
考虑到上面JSON的短处。我使用SwiftyJSON进行解析,如下所示:
let json:JSON = JSON(data:myData)
var catCollections:[CategoryCollection] = []
//gather category collections of articles
for (index: String, cat: JSON) in json["categories"] {
//collect articles within each category
var articles:[ArticleItem] = []
for(index:String, art:JSON) in cat["articles"] {
let artTitle = art["title"].string
let artImage = art["image"].string
let artUrl = art["url"].string
if(artTitle != nil && artUrl != nil) {
let articleItem = ArticleItem(title: artTitle!, url: artUrl!, imageURL: artImage)
articles.append(ArticleItem)
}
}
//create category collection for each category
let catTitle = cat["category"].string ?? ""
let catCollection = CategoryCollection(title: catTitle, articles: articles)
catCollections.append(catCollection)
}
var callout:CalloutItem?
//check for existance of callout item
if let calloutTitle = json["callout"]["title"].string {
if let calloutUrl = json["callout"]["url"].string {
callout = CalloutItem(title: calloutTitle, url: calloutUrl, imageURL: json["callout"]["image"].string)
}
}
下面是一个解决方案,我将使用它循环遍历JSON的“代码”,并获取(或打印)每个人的姓名
let = JSON(data : myData)
if let codes = json["response"]["codes"].array {
for eachCode in codes {
let name = eachCode["name"]
print("Name: \(name)")
// or do whatever you'd like with each 'name'
}
}
这就是你所需要的。我不会为你用过的其他东西烦恼。我希望这能帮到你
let = JSON(data : myData)
if let codes = json["response"]["codes"].array {
for eachCode in codes {
let name = eachCode["name"]
print("Name: \(name)")
// or do whatever you'd like with each 'name'
}
}
