您可以像这样获得 Resources 目录的路径，

You can get the path to the Resources directory like this,

NSString * resourcePath = [[NSBundle mainBundle] resourcePath];

然后将 Documents 附加到路径中，

Then append the Documents to the path,

NSString * documentsPath = [resourcePath stringByAppendingPathComponent:@"Documents"];

然后你可以使用 NSFileManager的任何目录列表API 。

NSError * error;
NSArray * directoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsPath error:&error];
