如何在NSLibraryDirectory\myFolder？

中将所有文件和目录重命名为小写

我发现我可以使用：

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

重命名目录。

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

获取包含目录内容的数组，但我如何检查directoryContent[0]是否为目录或文件。

Answer 1

您可以使用它来检查NSUrl是否是目录或文件：

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);
    }
}

要重命名目录的所有内容，您可以使用：

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];
        }
    }
}

//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];
            }
        }
    }
}
