Question

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，但不会在次要启动时崩溃。

在评论出一些addSubView方法后，调试器终于给了我一条信息

它在[super viewDidLoad]上崩溃了。调试器声明：

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，我遇到了同样的错误消息“无法访问变量”。

正如其中一条评论所述，我的问题是我正在调试我的发布版本而不是调试版本。
