Question

我尝试从服务器下载一个JSON字符串，它看起来不应该这样。抱歉格式化，第一次使用stackoverflow ..

正如您在收到的字符串和来自php的var_dump的比较中所看到的，来自arr[LISTING][<this ones>]的密钥已被删除..因此我的进一步JSON解码会将来自arr[LISTING][<this one>]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？

我尝试了什么：

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

这是什么样的：

{"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":""}]}}}

应该是什么样的：

您是否尝试过适用于iOS的JSON库？它有一个非常方便的方法：

NSArray *responseValues = [responseString JSONValue];

或

NSDictionary *responseValues = [responseString JSONValue];

您可以将其作为数组或字典获取，因为JSONValue方法返回id，因此您可以适应您正在接收的任何内容。

您可以在这里找到图书馆： https://github.com/stig/json-framework

希望它有所帮助。
