Xcode NSUTF8StringEncoding后的字符串问题

我试图从服务器下载一个JSON字符串，但它看起来不像应该的样子。 很抱歉格式化，第一次使用stackoverflow

从接收到的字符串和php的var_转储的比较中可以看出， 已删除

arr[LISTING][

中的密钥。。因此，我进一步的JSON解码将来自

arr[LISTING][

的条目视为一个值，而不是另一个数组子维度

有什么想法吗

我尝试的是：

NSData *serverRes = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *serverRes_str=[[NSString alloc]initWithData:serverRes encoding:NSUTF8StringEncoding];
NSLog(@"%@",serverRes_str);

这看起来像什么：

{"STATUS":{"RESULT":"OK","CODE":205,"INFO":"GET_PROJECTS","AUTHENTICATED":1,"USERID":1,"ACCESS":1000,"SYSTEM_NAME":"Testdatei","SSL":false,"IDENTIFIER":""},"CONTENT":{"GET_PROJECTS":{"COUNT":7,"LISTING":[{"ID":"1","NAME":"Devel","CREATION_DATE":"1357116685","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"30","NAME":"p5","CREATION_DATE":"1365866791","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"29","NAME":"p4","CREATION_DATE":"1365866785","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"28","NAME":"p3","CREATION_DATE":"1365866780","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"27","NAME":"p2","CREATION_DATE":"1365866773","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"26","NAME":"p1","CREATION_DATE":"1365866767","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""},{"ID":"4","NAME":"Testimmortals","CREATION_DATE":"1362388820","CREATED_BY":"admin","TYPE":"PROJECT","PUBLIC":false,"PRIVAT":false,"ACCESS":3,"THUMBNAIL":""}]}}}

它应该是什么样子的：

您是否尝试过iOS附带的JSON库？ 它有一个非常方便的方法，如下所示：

NSArray *responseValues = [responseString JSONValue];

或

• 您可以以数组或字典的形式获取它，因为

  JSONValue

  方法返回一个

  id

  ，所以您可以适应所接收的任何内容

你可以在这里找到图书馆：

希望有帮助。

好吧，既然字符串已经错了，那就不是json解码的错。。我认为这甚至是api。。让我深入探讨一下……好吧，看起来我已经修复了->json_encode（$array，json_FORCE_OBJECT）遗漏了这个力……那么问题是来自您的php文件？

NSDictionary *responseValues = [responseString JSONValue];
