Swift 2 Json utf8字符串字符错误

Question

我有正在工作的Json文件和应用程序，但是我有文本encoding问题。

我的Json文件输出示例

{"status":"SUCCESS","data":[{"id":"21","title":"I'm working on project","description":"Lorem ipsum dolor sit er elit lamet, consectetaur cilliim adipisicin"}]}

Json Parse Functions，我添加了一些可以在下面看到的函数

    func initArrayCategory(){
        self.getResponseFromURL(self.getStringURLWithJSONFormatForUserAPI(URL_API_NEWS_CATEGORIES), withParams: nil, Success: { (operation, responseObject) -> () in
            if let success = responseObject[API_PARAM_STATUS] as? String{
                if success == "SUCCESS"{
                    if let data = responseObject[API_PARAM_DATA] as? NSMutableArray{
                        self.arrayCategory = data
                    }
                }
                self.Category.reloadData()
            }

            }, Failure: { (operation, error) -> () in
                if error.localizedDescription == "The network connection was lost."{
                    self.initArrayCategory()
                }
            }, showLoader: true, hideLoader: true)
    }



    func postResponseFromURL(strURL: String, withParams dictParams:NSDictionary?, Success:(operation: AFHTTPRequestOperation!, responseObject:AnyObject!)->(),Failure:(operation: AFHTTPRequestOperation!, error:NSError!)->(),showLoader isShowDefaultLoader:Bool,showAnimated isShowLoaderAnimated:Bool, hideLoader isHideDefaultLoader:Bool)
    {

        let hudprogress = MBProgressHUD()

        if isShowDefaultLoader{
            MBProgressHUD.showHUDAddedTo(self.view, animated: true)
            hudprogress.mode = MBProgressHUDModeDeterminate
            hudprogress.labelText = "Loading"
        }

        let manager = AFHTTPRequestOperationManager()
        manager.responseSerializer.acceptableContentTypes = NSSet(array: ["text/html", "application/json"]) as Set<NSObject>

        manager.POST(strURL, parameters: dictParams, success: { (operation, responseObject) -> Void in
            //println("RESPONSE DATA: " + responseObject.description)

            if isHideDefaultLoader{
                MBProgressHUD.hideAllHUDsForView(self.view, animated: true)
            }

            Success(operation: operation, responseObject: responseObject
            )

            }) { (operation, error) -> Void in

                print("Response:    \(operation.responseObject)")
                print("Error:  " + error.localizedDescription)

                Failure(operation: operation, error: error)
                hudprogress.hide(true)
        }
    }



let URL_API_HOST:String = "http://www.blabla.com/Items/"

    func postResponseFromURL(strURL: String, withParams dictParams:NSDictionary?, Success:(operation: AFHTTPRequestOperation!, responseObject:AnyObject!)->(),Failure:(operation: AFHTTPRequestOperation!, error:NSError!)->(),showLoader isShowDefaultLoader:Bool, hideLoader isHideDefaultLoader:Bool)
    {
        self.postResponseFromURL(strURL, withParams: dictParams, Success: Success, Failure: Failure, showLoader: isShowDefaultLoader, showAnimated: true, hideLoader: isHideDefaultLoader)
    }


    func setObjectToUserDefaults(object:AnyObject, forKey strKey:String, writeToDisk isWrite:Bool )
    {
        let defaults = NSUserDefaults.standardUserDefaults()
        defaults.setObject(object, forKey: strKey)
        if isWrite{
            defaults.synchronize()
        }
    }



    func getStringURLWithJSONFormatForUserAPI(strAPI:String)->String{
        return self.getStringURLForUserAPI(strAPI, withJSONFormat: true)
    }


    func getStringURLForUserAPI(strAPI:String, withJSONFormat isJSON:Bool)->String{

        var strURL:String = self.getBaseURl()
        strURL += strAPI

        if isJSON
        {
            strURL = self.addJSONFormatInURL(strURL)
        }

        return strURL
    }


    func getBaseURl()->String{
        return URL_API_HOST
    }


    func addJSONFormatInURL(strURL:String)->String{
        return strURL + URL_API_FORMAT_JSON
    }

我的视图控制器

class ViewController: UIViewController {


    var detailTitle:String?
    var detailDesc:String?

    @IBOutlet weak var textim: UILabel!
    @IBOutlet weak var textbig: UITextView!

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func viewDidLoad() {
        super.viewDidLoad()

    textbig.text = detailDesc
    textim.text = detailTitle


}

Mysql表Mysql文件

-- ----------------------------
--  Table structure for `App`
-- ----------------------------
DROP TABLE IF EXISTS `App`;
CREATE TABLE `App` (
  `id` int(21) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) DEFAULT NULL,
  `description` text,
  `image` varchar(128) DEFAULT NULL,
  `video` text,
  `likes` int(21) DEFAULT NULL,
  `visits` int(21) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=27 DEFAULT CHARSET=utf8;

表中的MySQL实际值

('21', 'I'm working on project', 'Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation.  ', '7292754.jpg', '', '2', '26')

远程连接php文件

$db_host="my host";   // your mysql database host name
$db_username="myusername";  // username
$db_pass="my past";                 // password
$connnect=mysql_connect("$db_host","$db_username","$db_pass") or die("Databese Error, Please check your connection values !");  
@mysql_select_db ("App");  // Select Your Database


@mysql_query("SET NAMES utf8");
@mysql_query("SET CHARACTER SET utf8");
@mysql_query("SET COLLATION_CONNECTION = 'utf8_general_ci'");

远程PHP文件

header("Content-type: application/json; charset=utf-8");
include("connect.php");

$q = "Select * from App";
$r = mysql_query($q) or die(mysql_error());

if(mysql_num_rows($r) > 0) {

    $arr = array();

            while ($row = mysql_fetch_assoc($r))
            {
                $arr[] = $row;
            }
            echo json_encode(array('status'=>"SUCCESS",'data'=>$arr));
        }
        else {
            echo json_encode(array('status'=>"FAIL"));
        }       

输出量

textim.text =  I'm working on project

一定是

textim.text = I'm working on project

json file coming title = I'm working on project

请帮我

最后我下了决心，我认为代码需要太多的人！ 谢谢@EricD。我尝试了您的链接代码，但我进行了一些更改，现在工作成功！

代码;

if let detailanother =  detailTitle {


            do {
                let encodedData = detailanother.dataUsingEncoding(NSUTF8StringEncoding)!
                let attributedOptions : [String: AnyObject] = [
                    NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                    NSCharacterEncodingDocumentAttribute: NSUTF8StringEncoding
                ]
                let attributedString = try NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil)
                self.textim.text = attributedString.string
            } catch {
                fatalError("Unhandled error: \(error)")
            }


    }

谢谢大家！ 好的编码！
