How to zip folders in iPhone SDK?

Question

In my Application,I am taking screenshots of image View and then I am saving those screen shots in document folder of the application.Now I want to Email all those images with the same folder structure they are in.Zipping all the folders containing the images and then attaching the zip file to the mail will solve the problem but how can I zip these folders and then attach them to the mail?

Any help is appreciated!

Answer 1

I have used this code to create a zip file of the documents directory of my app and it worked

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [paths objectAtIndex:0];
BOOL isDir=NO;
NSArray *subpaths;
NSString *exportPath = docDirectory;
NSFileManager *fileManager = [NSFileManager defaultManager];    
if ([fileManager fileExistsAtPath:exportPath isDirectory:&isDir] && isDir){
    subpaths = [fileManager subpathsAtPath:exportPath];
}

NSString *archivePath = [docDirectory stringByAppendingString:@"/test.zip"];

ZipArchive *archiver = [[ZipArchive alloc] init];
[archiver CreateZipFile2:archivePath];
for(NSString *path in subpaths)
{
    NSString *longPath = [exportPath stringByAppendingPathComponent:path];
    if([fileManager fileExistsAtPath:longPath isDirectory:&isDir] && !isDir)
    {
        [archiver addFileToZip:longPath newname:path];      
    }
}

if([archiver CloseZipFile2])
    NSLog(@"Success");
else
    NSLog(@"Fail");

ZipArchive is an Objective-C class to compress or uncompress zip files, which is base on open source code "MiniZip".

It can be used for iPhone application development, and cocoa on Mac OSX as well.
