Question

I am using ELCimagepicker to attach multiple image to an email but I’m not sure how to make every NSData unique so i can attach them to my email.

>

- (void)launchController {
  ELCAlbumPickerController *albumController = [[ELCAlbumPickerController alloc] initWithNibName:@"ELCAlbumPickerController" bundle:[NSBundle mainBundle]];
  ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:albumController];
  [albumController setParent:elcPicker];
  [elcPicker setDelegate:self];
  [self presentModalViewController:elcPicker animated:YES];
 }

- (void)elcImagePickerController:(ELCImagePickerController *)picker     didFinishPickingMediaWithInfo:(NSArray *)info {

  [self dismissModalViewControllerAnimated:YES];
  int i = 0;
  for(NSDictionary *dict in info) {
     i++;
     UIImageView *imageview = [[UIImageView alloc] initWithImage:[dict     objectForKey:UIImagePickerControllerOriginalImage]];
     NSData *name = UIImageJPEGRepresentation(imageview, 1.0);
   }

}

Download and drag the Objective-Zip, MiniZip and ZLib drag in to your project from this link http://code.google.com/p/objective-zip/downloads/list (Objective-zip).. import the files: ZipFile.h, ZipException.h, FileInZipInfo.h, ZipWriteStream.h, ZipReadStream.h, zlib.h

Use the following code:

NSString *stringPath1 = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]];
    NSString *FileName=[stringPath1 stringByAppendingPathComponent:@"Your file name"];


    NSString *stringPath=[stringPath1 stringByAppendingPathComponent:[@"Your file name" stringByAppendingFormat:@".zip"]];
    NSArray *files = [[NSFileManager defaultManager]contentsOfDirectoryAtPath:FileName error:&error];
    ZipFile *zipFile = [[ZipFile alloc]initWithFileName:stringPath mode:ZipFileModeCreate];

    for(int i = 0;i<files.count;i++){

        id myArrayElement = [files  objectAtIndex:i];
        NSLog(@"add %@", myArrayElement);

        NSString *path = [FileName stringByAppendingPathComponent:myArrayElement];
        NSDictionary *attributes = [[NSFileManager defaultManager]attributesOfItemAtPath:path error:&error];
        NSDate *Date = [attributes objectForKey:NSFileCreationDate];

        ZipWriteStream *streem = [zipFile writeFileInZipWithName:myArrayElement fileDate:Date compressionLevel:ZipCompressionLevelBest];
        NSData *data = [NSData dataWithContentsOfFile:path];
        [streem writeData:data];
        [streem finishedWriting];
    }

    [zipFile close];
