Xcode-编码 Segue 期间的 EXC_BAD_ACCESS

Question

在我的应用程序中，当满足特定条件时，我尝试在代码中编写一个segue。我使用 [self PerformSegueWithIdentifier:Sender] 调用 Segue。这在 IBAction 中调用，通过按下 UIButton 来调用。但是，我收到 EXC_BAD_EXCESS 错误消息。实际的错误消息附加到不同的代码行，但我认为它仍然指的是基于注释掉 segue 时发生的情况的 segue。通过 NSLogging，我确实知道按钮确实正在调用 IBAction。

创建 Button 的方法：

- (void)gameOver {
[run invalidate];
[xViewTimer invalidate];
[gameTimer invalidate];

gameOverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
gameOverView.backgroundColor = [UIColor blueColor];


CGRect f = CGRectMake(0, 20, 320, 100);

scoreIs = [[UILabel alloc] initWithFrame:f];
scoreIs.textAlignment= UITextAlignmentCenter;
scoreIs.adjustsFontSizeToFitWidth = YES;
scoreIs.backgroundColor = [UIColor clearColor];
scoreIs.font = [UIFont systemFontOfSize:26];
[scoreIs setText:@"You Finished With A Score Of:"];

UILabel *showPoints = [[UILabel alloc] initWithFrame:CGRectMake(0, 80, 320, 100)];
showPoints.textAlignment = UITextAlignmentCenter;
showPoints.adjustsFontSizeToFitWidth = YES;
showPoints.backgroundColor = [UIColor clearColor];
showPoints.font = [UIFont systemFontOfSize:50];
[showPoints setText:[NSString stringWithFormat:@"%d", points]];

UIButton *playAgainButt = [UIButton buttonWithType:UIButtonTypeRoundedRect];
playAgainButt.frame = CGRectMake(self.view.center.x-70, 200, 140, 50);
[playAgainButt setTitle:@"Play Again" forState:UIControlStateNormal];
[playAgainButt addTarget:self action:@selector(newGame) forControlEvents:UIControlEventTouchUpInside];

UIButton *toMain = [UIButton buttonWithType:UIButtonTypeRoundedRect];
toMain.frame = CGRectMake(self.view.center.x-70, 280, 140, 50);
[toMain setTitle:@"Main Menus" forState:UIControlStateNormal];
[toMain addTarget:self action:@selector(mainMenuSegue:) forControlEvents:UIControlEventTouchUpInside];

scoreIs.hidden = NO;

[gameOverView addSubview:toMain];
[gameOverView addSubview:playAgainButt];
[gameOverView addSubview:showPoints];
[gameOverView addSubview:scoreIs];
[self.view addSubview:gameOverView];

NSLog(@"Game Over");
}

然后调用 mainMenuSegue：

- (IBAction)mainMenuSegue {
    [self performSegueWithIdentifier:@"menu" sender:self]; 
}

在我的 Storyboard 中有一个带有标识符“menu”的模态 Segue。

我发现的关于该主题的其他几篇文章主要回答了与内存管理相关的解决方案。我在 IOS 5 上使用 ARC，所以我认为这不是问题。非常感谢所有帮助，我可以发布任何其他可能有帮助的代码。

我认为你想要这个，

- (IBAction)mainMenuSegue:(id)sender {
  [self performSegueWithIdentifier:@"menu" sender:sender];
}

我认为 self 没有你认为的上下文
