如何获取iPhone资源文件夹中的文件夹和文件列表？ [英] How get list of folders and files from resource folder in iPhone?

问题描述

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];
