JSON 데이터를 IOS6 앱의 섹션과 함께 표시하고 싶습니다.

Question

공유 Google 캘린더 IOS에서 내 이벤트를 가져 와서 테이블 뷰에 표시하고 있습니다. 현재로서는 이벤트 제목을 제목으로, 이벤트 시간을 부제로 표시하는 것이 간단합니다. 예를 들어 3 월 31 일에 그룹의 "세부 사항"으로 표시된 시간과 함께 모든 이벤트가 섹션 헤더로 사용됩니다 ()

내 코드는 다음과 같습니다. this :

@interface MasterViewController() { 
    NSArray *events; 
} 
@end 

@implementation MasterViewController 

-(void)viewDidAppear:(BOOL)animated 
{ 
    //show loader view 
    //[HUD showUIBlockingIndicatorWithText:@"Fetching JSON"]; 


    //make HTTP call 
    NSString* searchCall = [NSString stringWithFormat:@"http://www.google.com/calendar/feeds/kao1d80fd2u5kh7268caop11o4%%40group.calendar.google.com/public/full?alt=json"]; 

    [JSONHTTPClient getJSONFromURLWithString: searchCall 
            completion:^(NSDictionary *json, JSONModelError *err) { 

             //got JSON back 
             NSLog(@"Got JSON from web: %@", json); 

             if (err) { 
              [[[UIAlertView alloc] initWithTitle:@"Error" 
                     message:[err localizedDescription] 
                    delegate:nil 
                  cancelButtonTitle:@"Close" 
                  otherButtonTitles: nil] show]; 
              return; 
             } 

             //initialize the models 
             events = [CalendarModel arrayOfModelsFromDictionaries: 
               json[@"feed"][@"entry"] 
               ]; 

             if (events) NSLog(@"Loaded successfully models"); 

             //show the videos 
             [self.tableView reloadData]; 

            }]; 


} 
;

          ]; 
    cell.detailTextLabel.text = [formatter stringFromDate: gmtDate]; 


    return cell; 
} 

@end

내 json event.startdate를 섹션 헤더로 사용하는 방법이 있습니까?

Answer 1

개인적으로, 나는 당신이하려고하는 것이 아니기 때문에 거기에 두 번째로 게시 한 코드를 무시할 것입니다.

머리글과 자막을 설정하는 코드 부분은 다음 두 줄입니다. cell.textLabel.text = [NSString stringWithFormat : @ "% @", event.title]; cell.detailTextLabel.text = [formatter stringFromDate : gmtDate];

그래서 표제를 날짜로 사용하려면 cell.textLabel.text 값으로 지정하십시오.

Answer 2

섹션을 원한다면.

섹션의 수는 1

그런 다음 당신이이 테이블 방법을 살펴 할 수 있습니다보다 큰 있는지 확인합니다. 정확한 케이스 및 사용자 정의 요구 사항에 따라 적절하게 변경할 수 있습니다.

(NSString*) tableView:(UITableView*)tableView titleForHeaderInSection:(NSInteger)section{ 
    } 

(CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section{ 
} 

(UIView*)tableView:(UITableView*)table viewForHeaderInSection:(NsInteger)section{ 
} 

이 정보가 도움이되기를 바랍니다. 나는 현재 일반적으로 사용할 수있는 시간이 없다는 예를 들고 싶지만 필요한 경우 제공 할 수 있습니다.
