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];
}

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

Answer 1

Get the app from this link
https://github.com/elc/ELCImagePickerController
and following changes from the code
using for loop
-(IBAction)launchController
{
ELCAlbumPickerController *albumController = [[ELCAlbumPickerController alloc] initWithNibName:#"ELCAlbumPickerController" bundle:[NSBundle mainBundle]];
ELCImagePickerController *elcPicker = [[ELCImagePickerController alloc] initWithRootViewController:albumController];
[albumController setParent:elcPicker];
[elcPicker setDelegate:self];
ELCImagePickerDemoAppDelegate *app = (ELCImagePickerDemoAppDelegate *)[[UIApplication sharedApplication] delegate];
[app.viewController presentModalViewController:elcPicker animated:YES];
[elcPicker release];
[albumController release];
[self buttonPressed];
}
- (void)buttonPressed
{
// Create image picker controller
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
// Set source to the camera
imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
// Delegate is self
imagePicker.delegate = self;
// Allow editing of image ?
imagePicker.allowsImageEditing = NO;
// Show image picker
[self presentModalViewController:imagePicker animated:YES];
}
- (void)emailImage:(UIImage *)image
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
// Set the subject of email
[picker setSubject:#"Picture from my iPhone!"];
// Add email addresses
// Notice three sections: "to" "cc" and "bcc"
[picker setToRecipients:[NSArray arrayWithObjects:#"emailaddress1#domainName.com", #"emailaddress2#domainName.com", nil]];
[picker setCcRecipients:[NSArray arrayWithObject:#"emailaddress3#domainName.com"]];
[picker setBccRecipients:[NSArray arrayWithObject:#"emailaddress4#domainName.com"]];
// Fill out the email body text
NSString *emailBody = #"I just took this picture, check it out.";
for (int i=0; i<[imagedelegate.imgarray count]; i++)
{
UIImageView *image=[[UIImageView alloc] init];
image=[imagedelegate.imgarray objectAtIndex:i];
// This is not an HTML formatted email
[picker setMessageBody:emailBody isHTML:NO];
// Create NSData object as PNG image data from camera image
NSData *data = UIImagePNGRepresentation(image);
// Attach image data to the email
// 'CameraImage.png' is the file name that will be attached to the email
[picker addAttachmentData:data mimeType:#"image/png" fileName:#"CameraImage"];
// Show email view
[self presentModalViewController:picker animated:YES];
// Release picker
[picker release];
}
}
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
// Access the uncropped image from info dictionary
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
// Dismiss the camera
[self dismissModalViewControllerAnimated:YES];
// Pass the image from camera to method that will email the same
// A delay is needed so camera view can be dismissed
[self performSelector:#selector(emailImage:) withObject:image afterDelay:1.0];
// Release picker
[picker release];
}

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];
