我的应用程序在我的Iphone上启动时崩溃 [英] My App crashes when launched on my Iphone
问题描述
我有一个问题：我的应用程序崩溃在我的Iphone（JB），虽然Xcode不抱怨什么。该应用程序在模拟器上可以正常工作。
I have a problem here : my app crashed on my Iphone (JB) though Xcode doesn't complain about anything. The app works fine on the simulator though.
但是，在设备日志中有这个：
However, there is this in the device logs :

任何想法可以是什么问题？
我已经花了一整天的时间，但...我被困了。
Any idea what the problem can be ? I've already spent my whole day on that, but... I'm stuck.
提前感谢...

这是调用URL的代码
NSURL * storeURL = [NSURL fileURLWithPath：[[self applicationDocumentsDirectory] stringByAppendingPathComponent：@TheLearningMachine.sqlite]];
NSURL *storeURL = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"TheLearningMachine.sqlite"]];
推荐答案
在你的应用程序的启动代码中，你正在调用 [NSURL fileURLWithPath：] ，它会引发异常。您需要检查要传递给它的字符串，可能会使用 NSLog（）调用。
Somewhere in your app's startup code you're making a call to [NSURL fileURLWithPath:], and it's raising an exception. You need to check what string is being passed to it, perhaps with an NSLog() call.
wild猜测是传递给它的值是 nil ，因为任何代码生成的路径失败，由于某种原因。很难说，没有看到实际代码）
(My wild guess is the value being passed to it is nil, because whatever code generates that path is failing for some reason. It's hard to say without seeing the actual code)
