需要用swift将json字符串：
{
"active": true,
"contacts": [],
"doc_type": "user",
"email": "xxx@yyy.com",
"name": "\u674e\u8302",
"password": "111111",
"phone": "13800001111",
"pinned": []
}转换为json字典对象变量
搜：
swift json parse string to dict
参考：
先去自己试试。
搞懂了之后，再去用别人的库：
然后用下面代码：
func testJsonDecode() {
let respJsonStr:String = "" +
"{" +
"\"active\": true," +
"\"contacts\": []," +
"\"doc_type\": \"user\"," +
"\"email\": \"x@x.com\"," +
"\"name\": \"\\u674e\\u8302\"," +
"\"password\": \"111111\"," +
"\"phone\": \"xxx\"," +
"\"pinned\": []" +
"}"
print("respJsonStr=\(respJsonStr)")
do{
let respJsonData:NSData = respJsonStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!
print("respJsonData=\(respJsonData)")
// let decodedJsonDict:NSDictionary = try NSJSONSerialization.JSONObjectWithData(respJsonData, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary
let decodedJsonDict:[String:AnyObject] = try NSJSONSerialization.JSONObjectWithData(respJsonData, options: NSJSONReadingOptions.MutableContainers) as! [String:AnyObject]
print("decodedJsonDict=\(decodedJsonDict)")
/*
decodedJsonDict=["active": 1, "phone": xxx, "password": 111111, "pinned": (
), "contacts": (
), "doc_type": user, "email": x@x.com, "name": 李茂]
*/
}catch let decodeJsonErr as NSError {
print("decodeJsonErr=\(decodeJsonErr)")
}
}然后继续想办法测试每个项的类型：
print(String(decodedJsonDict["active"].dynamicType)) //Optional<AnyObject>
print(String(decodedJsonDict["phone"].dynamicType)) //Optional<AnyObject>没办法，是因为前面强制了：[String:AnyObject]
所以都是：AnyObject
然后换成：
print(String((decodedJsonDict["active"] as! Bool ).dynamicType)) //Bool
print(String((decodedJsonDict["phone"] as! String).dynamicType)) //String然后可以去用别人的库了：
或
先去试试SwiftyJSON
很好用：
func testJsonDecode() {
let respJsonStr:String = "" +
"{" +
"\"active\": true," +
"\"contacts\": [" +
"\"contact-095dec1d-9bf2-45e3-bdc8-4f10acf7cd7e\"," +
"\"contact-351e6499-142b-4d89-bf79-0f756ee41a32\"," +
"\"contact-39ee1299-4e29-43cf-904f-d8826ce1b899\"" +
"]," +
"\"doc_type\": \"user\"," +
"\"email\": \"x@x.com\"," +
"\"name\": \”x\"," +
"\"password\": \"111111\"," +
"\"phone\": \"13811112222\"," +
"\"pinned\": []" +
"}"
print("respJsonStr=\(respJsonStr)")
let respJsonData:NSData = respJsonStr.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!
print("respJsonData=\(respJsonData)")
let decodedJsonDict = JSON(data: respJsonData)
print("decodedJsonDict=\(decodedJsonDict)")
/*
decodedJsonDict={
"active" : true,
"phone" : "13811112222",
"pinned" : [
],
"password" : "111111",
"contacts" : [
"contact-095dec1d-9bf2-45e3-bdc8-4f10acf7cd7e",
"contact-351e6499-142b-4d89-bf79-0f756ee41a32",
"contact-39ee1299-4e29-43cf-904f-d8826ce1b899"
],
"doc_type" : "user",
"email" : "x@x.com",
"name" : "x"
}
*/
let isActive:Bool = decodedJsonDict["active"].bool!
print("isActive=\(isActive)") //isActive=true
let name:String = decodedJsonDict["name"].string!
print("name=\(name)") //name=CrifanLi
let email:String = decodedJsonDict["email"].string!
print("email=\(email)") //email=x@x.com
let contactList:[String] = decodedJsonDict["contacts"].arrayObject as! [String]
print("contactList=\(contactList)") //contactList=["contact-095dec1d-9bf2-45e3-bdc8-4f10acf7cd7e", "contact-351e6499-142b-4d89-bf79-0f756ee41a32", "contact-39ee1299-4e29-43cf-904f-d8826ce1b899"]
} 即可。
