ZIP folder addition

[GoogleCodeExporter]

I needed to zip an entire folder tree...

// 2010-12-22, Michael Burford (michael@burford.net)
// "pathPrefix" should be nil or @"" the first call; lets the recursive calls 
store in subfolders in the zip file.
-(NSInteger) addFolderToZip:(NSString*)path pathPrefix:(NSString*)prefix {
    NSInteger   fileCount = 0;
    NSArray     *dirArray = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:nil];

    for (int i=0; i<[dirArray count]; i++) {
        NSString        *dirItem = [dirArray objectAtIndex:i];
        NSDictionary    *dict = [[NSFileManager defaultManager] attributesOfItemAtPath:[path stringByAppendingPathComponent:dirItem] error:nil];

        if ([[dict fileType] isEqualToString:NSFileTypeDirectory] || [[dict fileType] isEqualToString:NSFileTypeSymbolicLink]) { 
            //Recursively do subfolders.
            fileCount += [self addFolderToZip:[path stringByAppendingPathComponent:dirItem] pathPrefix:([prefix length]>0 ? [prefix stringByAppendingPathComponent:dirItem] : dirItem)];
        } else {
            //Count if added OK.
            if ([self addFileToZip:[path stringByAppendingPathComponent:dirItem] newname:([prefix length]>0 ? [prefix stringByAppendingPathComponent:dirItem] : dirItem)]) {
                fileCount++;
            }
        }
    }
    return fileCount;
}
