Renaming all files and directories in NSLibraryDirectory

How can I rename all files and directories to lower case in NSLibraryDirectory\myFolder?

I found that I can to use: 

[[NSFileManager defaultManager] moveItemAtPath:oldPath toPath:[oldPath lowercaseString] error:&error];

to renaming directories.

NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:path error:nil];

To getting array with directory contents but how I can check if directoryContent[0] is directory or file.

//Call [self purgeDirectory:__NSLibraryDirectoryPath];


+(void)purgeDirectory:(NSString *)directoryPath __deprecated_msg("For debug purposes only") {
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:directoryPath error:&error];
    for (NSString *itemPath in directoryContent) {
        BOOL isDir;
        if ([[NSFileManager defaultManager] fileExistsAtPath:itemPath isDirectory:&isDir]) {
            if (isDir) {
                [self purgeDirectory:itemPath];//subdirectory
            } else {
                [[NSFileManager defaultManager] removeItemAtPath:itemPath error:&error];
            }
        }
    }
}

You could use this to check if a NSUrl is a directory or file:

for (NSURL *item in directoryContent) {
    NSString *path = [item path];
    BOOL isDir;
    if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir]) {
        if (isDir) {
            NSLog(@"%@ is a directory", path);
        } else {
            NSLog(@"%@ is a file", path);
        }
    } else {
        NSLog(@"%@ does not exist", path);
    }
}

UPDATE:

To rename all contents of your directory you could use this:

NSArray *directoryContent = [fileManager contentsOfDirectoryAtPath:path error:nil];
BOOL isDir;
for (NSURL *item in directoryContent) {

    if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir]) {
        if (isDir) {
            // create a new directory with lowercase name,
            // move contents of old directory to the new one
            // then delete the old directory
        } else {
            [[NSFileManager defaultManager] moveItemAtPath:path toPath:[path lowercaseString] error:&error];
        }
    }
}
