线程1：EXC_BREAKPOINT（代码= EXC_i386_BPT，子代码= 0x0）错误

Question

我有一个我正在制作的iPad应用程序，但它在启动时崩溃，即使没有错误或警告，输出除了“（lldb）”之外没有输出任何内容，它标记了一个指针。

这是构建后崩溃的图像。

以下是代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   /* UIImage *myImage = [UIImage imageNamed:@"de_dust2.png"];
    myImageView = [[UIImageView alloc] initWithImage:myImage];

    myScrollView.contentSize = CGSizeMake(myImageView.frame.size.width, myImageView.frame.size.height);
    myScrollView.maximumZoomScale = 4.0;
    myScrollView.minimumZoomScale = 0.75;
    myScrollView.clipsToBounds = YES;
    myScrollView.delegate = self;
   // [myScrollView addSubview:myImageView];*/

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    [self.viewController setRed:1];
     [self.viewController setGreen:0];
    [self.viewController setBlue:0];
    [self.viewController setAlpha:1];
    [self.viewController checkRotation];
    return YES;
}

我现在也注意到错误是在[self.window makeKeyAndVisible];行给出的。

您的代码看起来没问题，崩溃可能是由于抛出窗口的XIB文件引发的异常引起的......

在Interface Builder中查看Window，并尝试临时删除对View Controller中存在的任何IBOutlet的所有引用...
