iOS 应用程序显示黑屏

Question

我正在尝试测试我正在使用的应用程序，但该应用程序显示黑屏，并且我在左侧面板上的线程 1 旁边看到一个黄色警告三角形(我忘记它叫什么了)，上面写着线程 1 ，并在队列下:com.apple.main-thread。此外，每次线程暂停时，它都会调出 main 方法和 this

@autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([DXAppDelegate class]));
    }

我猜是我的 ImageView 出了什么问题……我也不知道在哪里可以找到错误日志。感谢您的帮助另外，这是我的 .m 类

您可能错误地将 uiviews 绑定(bind)到您的 .h 文件，当您尝试手动执行此操作时会发生这种情况，请尝试使用 ctr 键并单击并拖动
