我是一个初学者 Objective-c 程序员，我坚持这一点。我从视图模板创建了一个应用程序，然后编辑了视图 xib 并添加了一个按钮并将其分配给 showEdicoes 函数，但是当我单击它时，它确实执行了该函数（我用断点测试）但它没有做任何事情，如果我再次点击它给出了一个 EXEC_BAD_ACESS
代码：
bipViewController.h（模板创建的默认）
#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 和 edicoesVC.m 是我要更改到的 TableViewController。
我没有改变 appDelegate 上的任何
东西我错过了什么？
谢谢我提前
编辑：附加代码
