在nsdictionary中获取特定键的值
我将json
parsing结果保存在一个dictionary
,如下所示:
{ "statusCode":"200", "body":[ { "status":"success", "remarks":null } ], "data":[ "abcd":[ { "category":"a", "title":"b", "id":"24" }, { "category":"c", "title":"crd", "id":"65" }, { "category":"ds", "title":"sd", "id":"18" } ] }, { "efgh":[ { "category":"ds", "title":"sd", "id":"18" }, { "category":"sd", "title":"sd", "id":"1" } ] }, { "ijkl":[ { "category":"ds", "title":"sd", "id":"18" }, { "category":"sd", "title":"sd", "id":"1" } ] } ] }
key @“data”的数据可以通过使用保存到数组中
NSMutableArray *getdata=[[NSMutableArray alloc]init]; getcat=[results objectForKey:@"data"];
现在我应该怎么做第一个索引内的values(category, title, id)
,即"abcd"
。
如果有人有任何知识,请看看。
谢谢大家。
以下将给你所需的对象
NSDictionary *dict=[results valueForKeyPath:@"data.abcd"][0];
对于个人:
NSString *categoryString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"Category"]; NSString *idString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"id"]; NSString *titleString=[[results valueForKeyPath:@"data.abcd"][0] objectForKey:@"title"];
也,
NSString *categoryString=dict[@"Category"]; NSString *idString=dict[@"id"]; NSString *titleString=dict[@"title"];
像这样检查:
NSString *value=[[[getcate valueForKey:@"abcd"] objectAtIndex:0] valueForKey:@"category"];
这是一个数组,所以使用objectAtIndex:
即[getcat objectAtIndex:0]
或getcat[0]
