我正在我的资源文件夹中进行文件夹结构，例如...资源=> MyData => S1 然后在S1 => Name.png，data.ppt

I am doing folder structure in my resource folder like... Resource => MyData => S1 then in S1=> Name.png, data.ppt

现在我想获取所有文件夹列表和文件名。这里MyData名称只是静态其他可能会改变。就像我可以添加S1，S2，S3和文件数量。那么如何通过Objective C阅读这些内容呢？我试过下面的代码。

Now I want to get all folder list and file names. Here MyData name will be only static other may change.Like I can add S1, S2 , S3 and number of files in that. So how to read these contents through Objective C? I tried below code.

NSString *bundlePathName = [[NSBundle mainBundle] bundlePath]; NSString *dataPathName = [bundlePathName stringByAppendingPathComponent:@"Resources"]; NSFileManager *fileManager = [NSFileManager defaultManager]; if ([fileManager fileExistsAtPath:dataPathName]) { NSLog(@"%@ exists", dataPathName); BOOL isDir = NO; [fileManager fileExistsAtPath:dataPathName isDirectory:(&isDir)]; if (isDir == YES) { NSLog(@"%@ is a directory", dataPathName); NSArray *contents; contents = [fileManager contentsOfDirectoryAtPath:dataPathName error:nil]; for (NSString *entity in contents) { NSLog(@"%@ is within", entity); } } else { NSLog(@"%@ is not a directory", dataPathName); } } else { NSLog(@"%@ does not exist", dataPathName); }

谢谢，

推荐答案

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];
