1、JSONString转换为字典
func getDictionaryFromJSONString(jsonString:String) ->NSDictionary{
let jsonData:Data= jsonString.data(using: .utf8)!
let dict = try?JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)
if dict != nil {
return dict as! NSDictionary
}return NSDictionary()
}
2、字典转换为JSONString
/**
字典转换为JSONString
- parameter dictionary: 字典参数
- returns: JSONString
*/
func getJSONStringFromDictionary(dictionary:NSDictionary) ->String {
if(!JSONSerialization.isValidJSONObject(dictionary)) {
print("无法解析出JSONString")return""}
let data : NSData! =try? JSONSerialization.data(withJSONObject: dictionary, options: [])asNSData!let JSONString= NSString(data:dataasData,encoding: String.Encoding.utf8.rawValue)returnJSONString!asString
}
