} 

我如何使用 iOS 从中提取数据

Answer 1

利用NSJSONSerialization.

NSError *jsonError = nil;
id allValues = [NSJSONSerialization JSONObjectWithData:[str dataUsingEncoding:NSUTF8StringEncoding]
                                                                      options:0
                                                                        error:&jsonError];

if(jsonError!=nil)
   NSLog(@"Json_Err: %@",jsonError);

NSArray *result = [(NSDictionary*)allValues objectForKey:@"data"];

为您的项目集成 Json sdk 并像这样放置以下代码...

NSStrig *jsonString = @"your json string";
NSDictionary *responseDictionary = [jsonString JSONValue];
