Question

현재 검색 디스플레이 컨트롤러를 세부보기로 세우려고하는데 행운이별로 없습니다! 검색 작업 및 제목 및 이미지 seguing mainTableView (원래 테이블보기) 있지만 searchdisplaytableview에서 segue 시도 할 때 충돌이 발생합니다.

self.navigationItem.title = [self.detailItem objectForKey:@"name"]; 

상세 뷰의 전체 코드는 다음과 같습니다 : .H

#import <UIKit/UIKit.h> 

@interface SearchDetailViewController : UIViewController<UISplitViewControllerDelegate> 


@property (strong, nonatomic) id detailItem; 

@property (strong, nonatomic) IBOutlet UIImageView *detailImage; 

@end 

하는 .m

#import "SearchDetailViewController.h" 

@interface SearchDetailViewController() 

@end 

@implementation SearchDetailViewController 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
{ 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) { 
     // Custom initialization 
    } 
    return self; 
} 

- (void)setDetailItem:(id)newDetailItem 
{ 
    if (_detailItem != newDetailItem) { 
     _detailItem = newDetailItem; 

     // Update the view. 
     [self configureView]; 
    } 
} 

- (void)configureView 
{ 
    // Update the user interface for the detail item. 

    if (self.detailItem) { 
     self.navigationItem.title = [self.detailItem objectForKey:@"name"]; 
     [self.detailImage setImage:[UIImage imageNamed:self.detailItem[@"image"]]]; 
    } 
} 


- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
} 

- (void)didReceiveMemoryWarning 
{

내가 잘못거야 어디서 누군가가 말해 줄 수주십시오? 이것은 나를 미치게하고있다 INSANE !!!

Answer 1

self.detailItem은 어떤 다른 사용자 정의 객체가 아닌 objectForKey에 응답하지 않는 상수 문자열이기 때문입니다.

클래스 정의가 게시되지 않았으므로 자세히 알려 드릴 수 없습니다.
