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？
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。

非常感谢您的帮助。
I was hoping you guys could help me what is wrong with my code that is causing my app to crash on my device but not the simulator. It is a very simple app, I just have local files displayed in a UIWebView. Here is what I am using in my .m
NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"localHTML/mobile"];
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
I'm only posting this code because I feel like something in here is causing the problem, but what do I know, let me know if you need to see something else.
Here is the crash log. Some of this probably isn't helpful, but I figured I'll post the entire thing since I don't know what to look for.

检查 Xcode 生成的应用程序包。它是否包含 localHTML/mobile 目录以及您期望的所有文件？
（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”）
Check the application bundle being produced by Xcode. Does it contain the localHTML/mobile directory and all the files you are expecting?
(Right-click on appname.app under the Products section in the Xcode navigator panel, select 'Reveal in Finder', then right-click on the app bundle in Finder and select 'Show package contents')
由于您尚未发布异常，我猜测问题是您将
nil传递给了+fileURLWithPath:。为什么你会在设备上得到nil而在模拟器上却没有？简单的答案：区分大小写。设备上的文件系统区分大小写，但 Mac OS X 上的默认 HFS+ 文件系统不区分大小写。您要求 localHTML/mobile/index.html，但如果其中任何字符的大小写错误，则-pathForResource:ofType:inDirectory:最终将返回nil在设备上。由于您尚未测试它是否为nil，因此您将其直接传递给+fileURLWithPath:，这可能会引发异常。Since you haven't posted the exception, I'm guessing the problem is you passed
nilto+fileURLWithPath:. Why would you getnilon the device but not the simulator? Simple answer: case sensitivity. The filesystem on the device is case sensitive, but the default HFS+ filesystem on Mac OS X is not. You're asking for localHTML/mobile/index.html, but if any of those characters have the wrong case, then-pathForResource:ofType:inDirectory:is going to end up handing backnilon the device. Since you haven't tested if it'snil, you're passing it directly to+fileURLWithPath:and this is likely throwing an exception as a result.好吧，我不太确定为什么会崩溃。从表面上看，你并没有做任何根本错误的事情。我猜这与文件路径或文件不存在有关。杀死它的行是
[NSURL fileURLWithPath:path]，您可以使用- (NSURL *)URLForResource:(NSString *)name withExtension:(NSString *)ext 子目录跳过该行:(NSString *)subpath而不是pathForResource:。不确定这是否能解决您的问题，但值得一试。编辑：哦，模拟器和设备之间的一个区别是设备上的文件系统区分大小写，而 osx/模拟器上则不区分大小写。您的文件名或文件路径是否存在大小写问题？
尝试一些 NSLog 看看问题出在哪里。
如果您在控制台中看到“Path is null”，那么您在
pathForResource调用中指定了错误。一个想法：
如果您已将文件添加到 Xcode 项目，但未将它们包含在构建目标中，则它们不会添加到应用程序包中。
如果 localHTML 和 mobile 是 Xcode 中的“组”，而不是实际的文件夹，那么在编译应用程序时它们将被忽略。相对于已编译的应用程序，Xcode 组没有任何意义（查看文件夹引用以了解在应用程序包中创建文件夹的方法）。
Well, I'm not exactly sure why this is crashing. From the looks of it you're not doing anything radically wrong. I'd guess it had something to do with the file path, or the file not being there. The line that's killing it is
[NSURL fileURLWithPath:path]and you can skip that line by using- (NSURL *)URLForResource:(NSString *)name withExtension:(NSString *)ext subdirectory:(NSString *)subpathinstead ofpathForResource:. Not sure if that will solve your problem, but it's worth a shot.Edit: oh, one difference between the simulator and the device, is the file system on the device is case-sensitive, while it's not on osx/the simulator. Could there be a case issue in your file name or file path?
Try some NSLog's to see where the problem is.
If you see in the console "Path is null" then you're specifying something wrong in your
pathForResourcecall.A thought:
If you've added files to your Xcode project, but not included them in the build target, they won't be added to app bundle.
if localHTML and mobile are "groups" in Xcode, not actual folders, then they're ignored when the app is compiled. Xcode groups mean NOTHING, in relation to the compiled app (look into folder references for a way to make folders in your app bundle).
