NSString到字典？或json然后到字典？获取字符串键的对象

我有一个字符串，然后我需要它作为json，所以我可以解析它并获取键的对象。NSString到字典？或json然后到字典？获取字符串键的对象

例如，我需要一个数组中的ID的所有对象来显示在一个表中。我该如何处理字符串？

对此提出建议？

这里的字符串：

{ 
    "COMMON": { 
    "RESULT_CD": "0000", 
    "RESULT_MSG": "SUCCESS", 
    "CATEGORY": "computing", 
    "SVC_ID": "7", 
    "TARGET": "list(VM)", 
    "REQUEST_DATE": "201410271741", 
    "PAGE_NO": 0, 
    "NUM_PER_PAGE": 0 
    }, 
    "DATA": { 
    "VM_LIST": [ 
     { 
     "@SVC_ID": "7", 
     "ID": "VMSPE0000000083", 
     "VM_ALIAS": "CV00900000083", 
     "VM_OPER_DESC": "Power On", 
     "MACHIN_STATUS_DESC": "[150748]success:virtual machine power on", 
     "USVC_DESC": "7/Running, No Change r/hurhurhur, Inc.", 
     "PURPOSE_NM": "Service_Default", 
     "VIRT_TYPE_DESC": "Para Virtualization", 
     "SERVER_STATUS_MSG": "VM running", 
     "VCPU_CNT": "2", 
     "MEM_SIZE_MB": "1024", 
     "VNIC_CNT": "1", 
     "OS_NAME": "CentOS_6.4_en_64" 
     }, 
     { 
     "@SVC_ID": "7", 
     "ID": "VMSPE0000000093", 
     "VM_ALIAS": "CV00900000093", 
     "VM_OPER_DESC": "Reboot", 
     "MACHIN_STATUS_DESC": "[150749]success:virtual machine reboot", 
     "USVC_DESC": "7/Running, No Change r/hurhurhur, Inc.", 
     "PURPOSE_NM": "Service_Default", 
     "VIRT_TYPE_DESC": "Para Virtualization", 
     "SERVER_STATUS_MSG": "VM running", 
     "VCPU_CNT": "1", 
     "MEM_SIZE_MB": "2048", 
     "VNIC_CNT": "1", 
     "OS_NAME": "Gentoo _2011-0 _en_64" 
     }, 
     { 
     "@SVC_ID": "7", 
     "ID": "VMSPE0000000096", 
     "VM_ALIAS": "CV00900000096", 
     "VM_OPER_DESC": "Vm Initialization", 
     "MACHIN_STATUS_DESC": "[163023]success:virtual machine running", 
     "USVC_DESC": "7/Running, No Change r/hurhurhur, Inc.", 
     "PURPOSE_NM": "Service_Default", 
     "VIRT_TYPE_DESC": "Para Virtualization", 
     "SERVER_STATUS_MSG": "VM running", 
     "VCPU_CNT": "2", 
     "MEM_SIZE_MB": "1024", 
     "VNIC_CNT": "1", 
     "OS_NAME": "OpenSuse_12.1_en_64" 
     } 
    ] 
    } 
}

编辑：

下面是我能够给谷歌。

NSDictionary *JSON = 
       [NSJSONSerialization JSONObjectWithData: [response dataUsingEncoding:NSUTF8StringEncoding] 
               options: NSJSONReadingMutableContainers 
                error:nil];

但是，比较字符串NSLog到JSON NSLog！

字符串：

的JSON缺少的东西！

这是好吗？

你知道任何关于'NSJSONSerialization'吗？ – 2014-10-27 08:51:13

...或关于谷歌，对此？ – 2014-10-27 08:51:37

请检查编辑，谢谢 – 2014-10-27 09:03:39

在上述字符串数组的第一家店，那么你可以用下面将其转换成JSONObject的

[NSJSONSerialization JSONObjectWithData:[yourArray dataUsingEncoding:NSUTF8StringEncoding] options:0 error:NULL]

您可以使用内置的称为NSJSONSerialization的iOS功能的NSString转换成JSON格式。因为你必须将NSString转换为NSData。

// jsonString = your string 
NSError *err; 
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; 
id objectChecker = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&err]; 

if ([objectChecker isKindOfClass:[NSArray class]]) 
{ 
    //your object is NSArray. 
} 
else if([objectChecker isKindOfClass:[NSDictionary class]]) 
{ 
    //your object is NSDictionary. 
} 
else 
{ 
    //your string doesn't contain proper json format. 
}

也许这会帮助你。 :)

NSString到字典？或json然后到字典？获取字符串键的对象
