我正在提升我的第一个ReactNative IOS应用。使用XCode和设备模拟器，一切都运行良好。但是当我在我的Iphone4S上安装应用程序（发布模式，保存为开发部署）时，它会崩溃，并生成一个非常不透明的崩溃报告（即使它已经被符号化...）。

编辑:与此同时，我已经能够在Xcode上复现这个bug并获得更明确的错误日志。
当我在AppDelegate.m中注释掉这行代码时，就会出现错误：
jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];
我需要取消注释这行代码：
jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
这是控制台日志：
