NSFileManager createDirectoryAtPath EXC_BAD_ACCESS

Question

我已经在这个工作了很长一段时间但似乎无法解决它.我有一个核心数据应用程序,也支持文档共享,因此我正在尝试在库文件夹中为sqlite db创建一个目录.

- (NSURL *)applicationPrivateDocumentsDirectory {
   NSString *libraryDirectory = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) lastObject];
   NSString *privateDocs = [libraryDirectory stringByAppendingPathComponent:@"PrivateDocuments"];
   NSFileManager *fileMgr = [[NSFileManager alloc] init];
   if (![fileMgr fileExistsAtPath:privateDocs]) {
      NSLog(@"Does not exist");
      NSError *error;
      [fileMgr createDirectoryAtPath:privateDocs withIntermediateDirectories:YES attributes:nil error:&error];
      NSLog(@"%@", [error description]);
   }
   NSURL *retURL = [NSURL fileURLWithPath:privateDocs];
   return retURL;
}

调试控制台输出"不存在",然后是"EXC_BAD_ACCESS"
.非常感谢任何帮助.

尝试添加:NSError*error = nil;
