Cocoa touch UITextView生成exc\u错误\u访问错误

在典型的导航应用程序中，我有一个自定义视图控制器，显示RootViewController中所选项目的详细信息

细节控制器有2个插座，与nib接口相连。我刚刚在ViewDidLoad中进行了一次分配，并在dealloc中进行了释放

在运行应用程序时，点击DetailController中的back按钮返回根控制器后，我从nombreTextView获得了一个exc_bad_访问权限

这是所有涉及的代码和个人资料中的信息

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];
}

RootViewController中的调用

- (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]; 
}

在概要文件中，我得到以下信息：

您不应该对非超级对象调用

dealloc

方法。将您的

dealloc

替换为下一个：

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

    [super dealloc];
}

我真不敢相信我错过了那个。这是一个不看屏幕就匆忙填写的代码。在回顾的时候，我只是看看实例是否在哪里变。
