Hello.

I've downloaded the ZipArchive library and I've added to my project. I use the method CreateZipFile2: , I add the file to the zip with addFileToZip:newname: and I close the zip calling back the method CloseZipFile2.

Then the zip is done in the finder, but in its inside I've an image that I can't open because it's empity (it's 0kb).

Someone knows why?

In attachment I put the portion of code that I use to do the zip.

    NSString* zipName = @"archivio.zip";
NSMutableArray* array = [[NSMutableArray alloc]init];
[array addObject:@"photo1.jpg"];

ZipArchive* zip = [[ZipArchive alloc] init];

 [zip CreateZipFile2:zipName];
 [zip addFileToZip:[array objectAtIndex:0] newname:[array objectAtIndex:0]];
 [zip CloseZipFile2];

[zip release];

Probably doesn't find the file--you should get better results by passing ZipArchive the complete path to a file, and not just the filename.

I just joined this project, so I realize the reply is a little late, but let me know if you still have troubles.
