UITextView가 exc_bad_access 오류를 생성합니다.

Question

일반적인 탐색 응용 프로그램의 RootViewController에서 선택한 항목의 세부 정보를 표시하는 사용자 지정보기 컨트롤러가 있습니다.

세부 컨트롤러에는 nib 인터페이스와 연결된 2 개의 콘센트가 있습니다. 방금 ViewDidLoad에서 할당을 만들고 dealloc에서 릴리스했습니다.

앱을 실행하면 세부 컨트롤러에서 뒤로 버튼을 눌러 루트 컨트롤러로 돌아간 후 nombreTextView에서 exc_bad_access를 얻습니다.

이것은 모두 관련 코드이며 프로필의 정보입니다.

EventoDetailViewControllerClass.h

@class YOEvento; 
@interface EventoDetailViewControllerClass : UIViewController 
{ 
    YOEvento *evento; 
    IBOutlet UITextView *nombreTextView; 
    IBOutlet UITextView *entradillaTextView; 
} 
@property (nonatomic, retain) YOEvento *evento; 
@property (nonatomic, retain) IBOutlet UITextView *nombreTextView; 
@property (nonatomic, retain) IBOutlet UITextView *entradillaTextView; 
@end 

EventoDetailViewControllerClass.m

#import "YOEvento.h" 
@implementation EventoDetailViewControllerClass 
@synthesize evento, nombreTextView, entradillaTextView; 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view from its nib. 
    self.nombreTextView.text = self.evento.nombre; 
    self.entradillaTextView.text = self.evento.entradilla; 

} 

- (void)dealloc { 
    [nombreTextView dealloc]; 
    [entradillaTextView dealloc]; 
    [evento dealloc]; 

    [super dealloc]; 
} 

프로필에서

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    // Create a new detailViewController 
    EventoDetailViewControllerClass *detailViewController = [[EventoDetailViewControllerClass alloc] initWithNibName:@"EventoDetailViewControllerClass" bundle:nil]; 
    // Get the current evento selected 
    YOEvento *auxEvento = [self.eventosList objectAtIndex:indexPath.row]; 
    // Pass the evento to detailViewController 
    detailViewController.evento = auxEvento; 

    // Reset auxEvento Reference 
    auxEvento = nil; 
    // Push detailViewController on top of the stack. 
    [self.navigationController pushViewController:detailViewController animated:YES]; 
    // Release detailViewController 
    [detailViewController release]; 
} 

나는 다음을 얻을 RootViewController의 전화 :

Answer 1

슈퍼 이외의 개체에 dealloc 메서드를 호출하면 안됩니다. dealloc을 다음으로 대체하십시오.

- (void)dealloc { 
    [nombreTextView release]; 
    [entradillaTextView release]; 
    [evento release]; 

    [super dealloc]; 
}
