Change From a UIView to a UITableView - objective-c

Question

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:
bipViewController.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;

Answer 1

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).
