Conditional unzip of files within a zip file?

[ColenMcA]

Hi,

When using SSZipArchive to extract the contents of an archive, we usually only need 1-2 files out of the dozens within the zip file, so extracting them all is pretty wasteful.

I'm planning to add a zipArchiveShouldUnzipFile: method to the delegate that will allow it to decide whether an individual file gets unzipped, which will be called before the WillUnzip method. Does this fit with your plans for SSZipArchive, and if so should I submit a pull request to incorporate this functionality into the main branch once I'm done?

Thanks for your help.

Irrelevant now. Read #163.

You can use this delegate method:
- (BOOL)zipArchiveShouldUnzipFileAtIndex:(NSInteger)fileIndex totalFiles:(NSInteger)totalFiles archivePath:(NSString *)archivePath fileInfo:(unz_file_info)fileInfo;

It was added by #131 in ZipArchive 0.3.3

Hum, but it's not optimal... it will totally stop unzipping any additional file. We should have a nicer way to filter files, so I'm reopening this issue.
