字典转JSON

func convertDictionaryToJSONString(dict:NSDictionary?)->String {
	let data = try? JSONSerialization.data(withJSONObject: dict!, options: JSONSerialization.WritingOptions.init(rawValue: 0))
	let jsonStr = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
	return jsonStr! as String
}

JSON转字典

func convertJSONStringToDictionary(text: String) -> [String:AnyObject]? {
	if let data = text.data(using: String.Encoding.utf8) {
		do {
			return try JSONSerialization.jsonObject(with: data, options: [JSONSerialization.ReadingOptions.init(rawValue: 0)]) as? [String:AnyObject]
		} catch let error as NSError {
			 print(error)
		}
	}
	return nil
