Change From a UIView to a UITableView

im a begginer Objective-c programmer and i stuck at this point. I Created an App from the View Template, then edited the view xib and add a button and assigned it to the showEdicoes function, but when i click it, it does execute the function(i tested with breakpoints) but it doesnt do anything, if i click again it gives an EXEC_BAD_ACESS

Codes:

bipViewControl开发者_开发技巧ler.h (the default one created by the template)

    #import <UIKit/UIKit.h>
#import "edicoesVC.h";
@interface bipViewController : UIViewController {
    edicoesVC *EdVC;
}
@property(nonatomic,retain)edicoesVC *EdVC;
- (IBAction) showEdicoes:(id)sender;

@end

bipViewController.m

#import "bipViewController.h"

@implementation bipViewController
@synthesize EdVC;

- (IBAction) showEdicoes:(id)sender {
    edicoesVC *Edic = [[edicoesVC alloc] initWithNibName:@"edicoesVC" bundle:[NSBundle mainBundle]];
    self.EdVC = Edic;
    [Edic release];
    [self.navigationController pushViewController:self.EdVC animated:YES];
    [self.EdVC release];
    }
.....
@end

edicoesVC.h and edicoesVC.m are the TableViewController to which i wan to change to.

i didnt changed anything on the appDelegate

what i missed?

Thanks i advance

EDIT: Additional code

bipAppDelegate.h

#import <UIKit/UIKit.h>

@class bipViewController;

@interface bipAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
   bipViewController *viewController;

    UINavigationController *navigationController;

I suspect the EXEC_BAD_ACCESS arises from the line:

[self.EdVC release];

This is because you have declared EdVC as (nonatomic, retain) in the header. This will perform a release followed by a retain when it is assigned a new value but you are performing an extra release. Take out the [self.EdVC release] line and move it to dealloc as:

[EdVC release];

Give this a try as it's the only thing I can think of, based on the code you've posted.

On the problem of nothing happening, I can't tell what's wrong from the code posted. Could you post the startup code of edicoesVC.h/edicoesVC.m?

You are using "self.EdVC" which is what I believe is causing your problem. When you access properties, just use the property name. For example:

[EdVC release];

One more thing, when coding in Objective-C classes are usually capitalized (i.e., BipViewController) and variables are lower case, i.e., eDic).
