当我使用[dic writeToFile:path atomically:YES];时，我收到了这样的崩溃：
0 CoreFoundation __exceptionPreprocess (in CoreFoundation) + 124
1 libobjc.A.dylib objc_exception_throw (in libobjc.A.dylib) + 56
2 Foundation _NSErrnoMessage (in Foundation) + 0

12 Foundation +[NSPropertyListSerialization dataWithPropertyList:format:options:error:] (in Foundation) + 48
13 Foundation -[NSDictionary(NSDictionary) writeToFile:atomically:] (in Foundation) + 180
我认为NSDictionary包含更多项目，当malloc内存失败时。 如何写一个大的字典文件？或其他最好的方式？ 那么有人可以帮助我取悦我做错了什么吗？
