Ios 使用SwiftyJSON遍历数据
我从互联网上调用了一个JSON文件Ios 使用SwiftyJSON遍历数据,ios,json,swift,swifty-json,Ios,Json,Swift,Swifty Json,我从互联网上调用了一个JSON文件 { "Editions": [ { "Version": "November", "Articles": [ { "title": "hello", "subheading": "Article 1", "content": "stuff"
{
"Editions": [
{
"Version": "November",

在我的第一个视图控制器上,我使用以下代码取出版本
func loaddata(){
Alamofire.request(.GET, "my JSON url")
.responseJSON { response in
//get json from response data
//print (response.data)
let json = JSON(data: response.data!)
//print(json)
//for loop over json and write all article titles articles array
for (key, subJson) in json["Editions"] {
let version = subJson["Version"].string
let stuff = Edition(Version: version!)
// print(stuff)
self.editions.append(stuff!)
}
// let x = self.editions[0].Version
// print ("\(x)")
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
}
然后,我使用segue将单击的版本传递到我的第二个视图控制器中
在第二个视图控制器上执行此操作后,我可以在视图中打印出版本的字符串
let worked = pleasework as String!
//print("\(worked)")
然后我想使用这个字符串遍历Json并提取相关内容
所以我调用函数并传递它
loaddata("\(worked)")
这是加载数据函数
func loaddata(verionTitle: String){
Alamofire.request(.GET, "my JSON url")
.responseJSON { response in
//get json from response data
let json = JSON(data: response.data!)
// print(json)
//for loop over json and write all article titles articles array
// print("\(verionTitle)")
for (key, subJson) in json["Editions"][0]["Articles"]{
// print(subJson)
//let versionmuted = version as String!
//print("\(version)")
//if verionTitle =
//if version == verionTitle{
//print("The month is \(version)")
let author = subJson["title"].string
//print("\(author)")
let subheading = subJson["subheading"].string
let content = subJson["content"].string
let Author = subJson["author"].string
//let image = subJson["image"].string
let stuff = Article(name: author!, subheading: subheading!, content: content!, author: Author!)
self.articles.append(stuff!)
}
//end iff
//if let content = subJson["content"].string {
// self.Content.append(content)
//}
//end for
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
}
我正在努力循环使用JSON,并且只提取与该版本相关的文章,我使用的是swiftyjson库
当前函数显然会打印出版本[0]中的所有文章
但是,我可以循环浏览所有版本并使用字符串仅打印该版本下的文章吗
比如说
for (key, subJson) in json["Editions"][0]["Version"] = veriontitle??{
//do stuff
}
希望我能解释清楚,希望你能帮忙
func loaddata(verionTitle: String){
Alamofire.request(.GET, "your json")
.responseJSON { response in
//get json from response data
let json = JSON(data: response.data!)
//print(json)
//start looping function pass through identifer from month, i've set October to 1 and so forth
func looping(Number: Int){
for (key, subJson) in json["Editions"][Number]["Articles"]{
let author = subJson["title"].string
//print("\(author)")
let subheading = subJson["subheading"].string
let content = subJson["content"].string
let Author = subJson["author"].string
let Image = subJson["image"].string
let stuff = Article(name: author!, subheading: subheading!, content: content!, author: Author!, image: Image!)
self.articles.append(stuff!)
//end loop
}
//end looping
}
//Get Version Titles, here is where I assign months to a number releavnt to where they are in the json
switch verionTitle{
case "November":
looping(0)
case "October":
looping(1)
case "December":
looping(2)
default:
print("no month")
}
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
}
