我的应用程序在模拟器上完美运行，它在控制台中没有显示任何警告或错误，但是当我在实际设备上测试我的应用程序时，它在启动应用程序时崩溃。我启用了本地通知服务。我在第一次加载视图时将大型图像文件从服务器存储到我的本地数据库中。但我试图在不存储图像的情况下启动应用程序，仍然无法正常工作。
以下是我得到的崩溃报告。 如果有人知道，请告诉我。 提前谢谢。

您正在尝试在应用程序启动期间从服务器存储大图像文件。根据您的代码，您尝试在主线程上同步。如果您在任何大量时间内阻止主线程，则用户界面变得无法接受地无响应。为了保持用户界面的响应，iOS包括一个看门狗机制。如果您的应用程序未能及时响应某些用户界面事件（启动，暂停，恢复，终止），则看门狗将终止您的应用程序。要解决此问题，我将异步调用CopyAndPaste：
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
CopyAndPaste();
});
