私は初心者のObjective-cプログラマーであり、この時点で立ち往生しています。ビューテンプレートからアプリを作成し、ビューxibを編集してボタンを追加し、それをshowEdicoes関数に割り当てましたが、クリックすると関数が実行されます(ブレークポイントでテストしました)が、何もしませんもう一度クリックすると、EXEC_BAD_ACESS が表示されます
コード:
bipViewController.h (テンプレートによって作成されたデフォルトのもの)
#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 と edicoesVC.m は、変更したい TableViewController です。
appDelegate で何も変更していませ
ん。見逃したものはありますか?
ありがとうございます 編集を進め
ます: 追加コード
