Xcode 오류 - 스레드 1 : signal SIGABRT

Question

간단한 RSS 응용 프로그램을 만들고 있는데 Objective-c가 좋지 않습니다. 응용 프로그램은 항상 성공적으로 빌드하고 아무런 오류나 경고가 없습니다, UITableView에서 RSS를 읽습니다. 언제든지 셀을 끝내고 main.m에서이 줄은 "줄 1 : 신호 SIGABRT"이 줄에 올 것입니다. :

return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); 

내 응용 프로그램의 정보 :

이 앱은 엑스 코드 버전에 의해 만들어집니다 : 앱은 아이폰과 맥북의 "마스터 - 세부 응용 프로그램"템플릿에서 생성 된 4.3.1 . 내가 사용하고 디버거가 LLDB하고 내 아이폰 시뮬레이터 내가 여기

스토리 보드

를 사용하고 5.1 인 Main.m입니다 :

#import <UIKit/UIKit.h> 

#import "AppDelegate.h" 

int main(int argc, char *argv[]) 
{ 

    @autoreleasepool { 
     return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); 
    } 
} 

AppDelegate.h은 다음과 같습니다

#import <UIKit/UIKit.h> 

@interface AppDelegate : NSObject <UIApplicationDelegate> { 

    UIWindow *window; 
    UINavigationController *navigationController; 
} 

@property (nonatomic, retain) IBOutlet UIWindow *window; 
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController; 

@end 

내 AppDelegate.m은 다음과 같습니다 :

#import "AppDelegate.h" 




#import "AppDelegate.h" 
#import "MasterViewController.h" 


@implementation AppDelegate 

@synthesize window; 
@synthesize navigationController; 


#pragma mark - 
#pragma mark Application lifecycle 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  
    // Override point for customization after app launch  

    [window addSubview:[navigationController view]]; 
    [window makeKeyAndVisible]; 
    return YES; 
} 


- (void)applicationWillTerminate:(UIApplication *)application { 
    // Save data if appropriate 
} 


#pragma mark - 
#pragma mark Memory management 

- (void)dealloc { 
    [navigationController release]; 
    [window release]; 
    [super dealloc]; 
} 


@end 

이것은 유일한 메시지 :

-(void)fetchRss 
{ 
    NSLog(@"fetch rss"); 
    NSData* xmlData = [[NSMutableData alloc] initWithContentsOfURL:[NSURL URLWithString: kRSSUrl] ]; 
    NSError *error; 

    GDataXMLDocument* doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:&error]; 

    if (doc != nil) { 
     self.loaded = YES; 

     GDataXMLNode* title = [[[doc rootElement] nodesForXPath:@"channel/title" error:&error] objectAtIndex:0]; 
     [self.delegate updatedFeedTitle: [title stringValue] ]; 

     NSArray* items = [[doc rootElement] nodesForXPath:@"channel/item" error:&error]; 
     NSMutableArray* rssItems = [NSMutableArray arrayWithCapacity:[items count] ]; 

     for (GDataXMLElement* xmlItem in items) { 
      [rssItems addObject: [self getItemFromXmlElement:xmlItem] ]; 
     } 

     [self.delegate performSelectorOnMainThread:@selector(updatedFeedWithRSS:) withObject:rssItems waitUntilDone:YES]; 
    } else { 
     [self.delegate performSelectorOnMainThread:@selector(failedFeedUpdateWithError:) withObject:error waitUntilDone:YES]; 
    } 

    [doc autorelease]; 
    [xmlData release]; 
}

정말 감사드립니다.

Answer 1

DetailViewController이라는 XIB를로드하려고하지만 XIB가 없거나 현재 대상의 멤버가 아닙니다.

Answer 2

SIGABRT는 일반적으로 포착되지 않는 예외가 있음을 의미합니다. 콘솔에 대한 자세한 정보가 있어야합니다.

Answer 3

SIGABRT는 다른 답변에서 언급했듯이 일반적으로 포착되지 않는 예외입니다. Objective-C에 대해 조금 더 배워야합니다. 문제는 아마도 UITableViewDelegate 메서드 didSelectRowAtIndexPath에 있습니다. 당신이 우리에게 당신이 테이블 데이터 소스 및 위임 방법을 처리하는 코드의 무언가를 보여줄 때까지

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 

난 당신에게 더 많은 것을 말할 수 없다.
