我遇到了JSON问题。我通过互联网搜索,但没有找到任何适用于我的解决方案。
为了更好地工作,我在* .json文件中保存了服务器的答案(JSON)。 JSON看起来像这样(简短版):
{ “数据”: “[{\” ID \ “:38,\” 名称\ “:\” 安东\ “},{\” ID \ “:160,\” 名称\ “:\” 克里斯托弗ETH \ “}]”}
我想解析数组,它以“数据”形式作为字符串发送。我试图从“数据”中获取String并在NSJSONSerialization中再次传递String。
这是正确的方法吗?
guard let path = NSBundle.mainBundle().pathForResource("names", ofType: "json") else {
print("Error finding File")
return
}
do {
let data:NSData? = NSData(contentsOfFile: path)
if let jsonResult =
try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {
let result = jsonResult["data"]
if(result == nil){
print("error")
}else{
//How can I convert the result! to an Stream to pass it to the JSONSerialization???
let stream = NSInputStream(/*result!*/)
let resultArray = try NSJSONSerialization.JSONObjectWithStream(stream: stream, options: NSJSONReadingOptions.MutableContainers) as? NSArray{
//Do something with array
}
}catch let error as NSError{
print("Error: \(error)")
return
}
答案 0 :(得分:0)
NSStream
,只需将JSON字符串转换为NSData
并再次调用JSONObjectWithData
。
guard let url = NSBundle.mainBundle().URLForResource("names", withExtension: "json"), jsonData = NSData(contentsOfURL: url) else {
print("Error finding File")
return
}
do {
let names = try NSJSONSerialization.JSONObjectWithData(jsonData, options: []) as! [String:AnyObject]
if let jsonResult = names["data"] {
let nameData = jsonResult.dataUsingEncoding(NSUTF8StringEncoding)!
let resultArray = try NSJSONSerialization.JSONObjectWithData(nameData, options: .MutableContainers) as! [[String:AnyObject]]
for item in resultArray {
print(item["name"]!, item["id"]!)
}
} else {
print("error")
}
} catch let error as NSError {
print(error)
}
