在 iOS 4 下，当我的应用程序从 xcode 安装时，它会在第一次启动时崩溃，但不会在后续启动时崩溃。

在注释掉一些 addSubView 方法后，调试器终于给了我一条信息

它在 [super viewDidLoad] 上崩溃。调试器状态：

无法访问变量“button1”

- (void)viewDidLoad {
    [super viewDidLoad];

    self.view.backgroundColor = [UIColor blackColor];

    UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];

来自控制台的断点信息：

尝试在调试模式下检查变量时出现相同的错误消息“无法访问变量”。

正如其中一条评论所提到的，我的问题是我正在调试我的发布版本而不是调试版本。
