구문 분석 값을 얻는 방법?

Question

아래 코드를 작성하고 있습니다.

NSDictionary* json = [NSJSONSerialization 
    JSONObjectWithData:responseData 
options:kNilOptions error:&error]; 

NSLog(@"%@",json); 

인쇄 사전 .... 등

(
     { 
     Contents =   (
         { 
       Id = 2; 
       LastUpdated = "/Date(1338048712847+0000)/"; 
       Title = "Webinar: HP & MS solutions for Mid-Market"; 
       Url = "http://infra2apps.blob.core.windows.net/content/VMMM019-HP-MS_MidMarket.wmv"; 
      }, 
         { 
       Id = 1; 
       LastUpdated = "/Date(1338048712773+0000)/"; 
       Title = "Webinar: Private Cloud with HP & MS"; 
       Url = "http://infra2apps.blob.core.windows.net/content/VMPC012-HPMS_PrivateCloud.wmv"; 
      } 
     ); 
     Id = 1; 
     ImageUrl = "http://infra2apps.blob.core.windows.net/eventapp/black-microsoft-logo.jpg"; 
     Name = "Unified Communications & Collaborations"; 
     Sessions =   (
         { 
       Description = "Microsoft Lync delivers Unified Communication to help People connect in new ways, anytime, anywhere. Learn how HP and Microsoft are helping customers transform their business infrastrucutre and gain greater productivity by making every communication an interaction that is more collaborative and engaging."; 
       EndDate = "/Date(1275822000000+0000)/"; 
       FriendlyName = TB3257; 
       Id = 1; 
       Location = "Building N-4105"; 
       Speakers =     (
             { 
         Company = Microsoft; 
         Email = "johndoe@microsoft.com"; 
         Name = "John Doe"; 
         Title = "Group Manager"; 
        } 
       ); 
       StartDate = "/Date(1275818400000+0000)/"; 
       Title = "Connecting People in New Ways with Microsoft Lync"; 
      }, 
         { 
       Description = "Microsoft Lync delivers Unified Communication to help People connect in new ways, anytime, anywhere.

       EndDate = "/Date(1275825600000+0000)/"; 
       FriendlyName = TB3258; 
       Id = 2; 
       Location = "Building N-4105"; 
       Speakers =     (
             { 
         Company = HP; 
         Email = "janedoe@hp.com"; 
         Name = "Jane Doe"; 
         Title = "Vice President"; 
        }, 
             { 
         Company = Microsoft; 
         Email = "johndoe@microsoft.com"; 
         Name = "John Doe"; 
         Title = "Group Manager"; 
        } 
       ); 
       StartDate = "/Date(1275822000000+0000)/"; 
       Title = "Connecting People in New Ways with Microsoft Lync - Part 2"; 
      } 
     ); 
    }, 

되고 그때 배열에 저장 한 후 그 다른 사전에 콘텐츠 값을 저장한다. 아래 코드는

NSDictionary *boothmenucontents = [json valueForKey: @"Contents"]; 
    NSMutableArray *dictResponseboothmenucontentsArray = [[NSMutableArray alloc] initWithObjects: boothmenucontents,nil]; 
for(int i = 0; i<[dictResponseboothmenucontentsArray count]; i++) 

    { 
     NSMutableArray *IdArrayboothmenucontentes=[[dictResponseboothmenucontentsArray objectAtIndex:i] valueForKey:@"Id"]; 

     NSLog(@"id array is %@",IdArrayboothmenucontentes); 
     for(int k=0;k<[IdArrayboothmenucontentes count];k++) 
     { 
      NSString * strcontentId= [NSString stringWithFormat:@"%@",[IdArrayboothmenucontentes objectAtIndex:k]]; 

      NSLog(@"strcontentId%@",strcontentId); 
      label.text=strcontentId; 
      [boothmenuidarrayvalues addObject:strcontentId]; 


      NSLog(@"%@",boothmenuidarrayvalues); 

     } 


    } 

마침내 내가

가이

"(\n 2,\n 1\n)", 
    "(\n 4,\n 3\n)", 
    "(\n 6,\n 5\n)", 
    "(\n 8,\n 7\n)", 
    "(\n 10,\n 9\n)", 
    "(\n 12,\n 11\n)" 

처럼 인쇄 boothmenuidarrayvalues를 인쇄

배열 ID를 저장하는 것입니다하지만 난 한 번만 콘텐츠 ID를 인쇄 할하지만로 인쇄 2 번에 1 행. 내가 잘못된 방법을 따르는 경우 해당 응답에 대한 루트를 제공하는 방법을 알려주십시오. 이 줄은 잘못 보이는

Answer 1

제발 도와주세요 ....... :

NSMutableArray *IdArrayboothmenucontentes=[[dictResponseboothmenucontentsArray objectAtIndex:i] valueForKey:@"Id"]; 

나는 당신이 어떻게 기대 모르겠어요,하지만이하는 것처럼 보이는 것을 사전 인 dictResponseboothmenucontentsArray의 i 번째 객체를 가져 와서 그 키의 "Id"라는 숫자 (즉, 숫자) 인 객체를 가져옵니다. 따라서 IdArrayboothmenucontentes에 배열이 아닌 NSNumber가 포함됩니다.

Answer 2

아마도 도움이 될 것입니다.

NSMutableArray *contenstsArray = [contentsDictionary ValueForKey:@"Contents"]; //Suppose you already brought all the json data into contentsDictionary 
NSMutableArray *idArray = [[NSMutableArray alloc] init]; 
for(NSMutableDictionary *idDic in contenstsArray) { 
    NSString *idString = [idDic valueForKey:@"Id"]; 
    [idArray addObject:]; 
}
