iPhone 应用程序在设备上崩溃，但在模拟器上则不然。使用 UIWebView 访问本地文件，可能的 [NSBundle mainBundle] 问题？

Question

我希望你们能帮助我，我的代码出了什么问题，导致我的应用程序在我的设备上崩溃，而不是在模拟器上崩溃。这是一个非常简单的应用程序，我只是在 UIWebView 中显示本地文件。这是我在 .m 中使用的内容

NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"localHTML/mobile"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

我只是发布此代码，因为我觉得这里的某些内容导致了问题，但我知道什么，如果您需要查看其他内容，请告诉我。

这是崩溃日志。其中一些可能没有帮助，但我想我会发布整个内容，因为我不知道要寻找什么。

检查 Xcode 生成的应用程序包。它包含 localHTML/mobile 目录和您期望的所有文件吗？

(右键单击 Xcode 导航器面板中“产品”部分下的 appname.app，选择“在 Finder 中显示”，然后右键单击 Finder 中的应用程序包并选择“显示包内容”)
