ios - IBAction 导致 EXC_BAD_ACCESS 错误

Question

我加载一个xib，然后我需要用一个按钮关闭它。我正在使用这个：

- (IBAction)donePressed:(id)sender {
    printf("Done\n");
    [self check_result];
    printf("Removing View\n");
   [self.view removeFromSuperview];
}

我像这样加载XIB：

AFUserFeedbackController *moviePlayer_af = [[AFUserFeedbackController alloc] initWithNibName:@"UserFeedback" bundle:nil];
UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];
moviePlayer_af.view.frame = backgroundWindow.frame;
[backgroundWindow addSubview:moviePlayer_af.view];

这就是我映射它的方式：

但是在按下按钮后，我得到的只是EXC_BAD_ACCESS错误，我得到了这个输出：

(lldb)

和EXC_BAD_ACCESS错误。我该如何解决？
