Capturing Image in Iphone - iphone

Question

I have a blank screen on which i click camera button and take photo and than that photo appears on my blank screen as a UIVIew and i'm adding multiple images from Camera to blank screen. The problem is sometimes i can add multiple images on blank screen but sometimes when i capture image and than all images on blank screen disappear and just shows the current image.
- (IBAction)openCameraOnAddButton:(id)sender {
//NSLog(#"openCameraOnAddButton");
[AddImagesToCanvasView setHidden:YES];
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
UIImage *image = [[info objectForKey:#"UIImagePickerControllerOriginalImage"] retain];
UIView *holderView;
if(image.size.width > image.size.height || image.size.width == image.size.height)
{
holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 180, 160)];
}
else{
holderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 240)];
}
UIImageView *imageview = [[UIImageView alloc] initWithFrame:[holderView frame]];
[imageview setImage:image];
NSLog(#"Tag By Default %d",(arc4random()%100)+10);
[holderView setTag:(int)objectDelegate.tagForHolderView];
[imageview setTag:((int)objectDelegate.tagForHolderView)+1];
[holderView addSubview:imageview];
UIPinchGestureRecognizer *pinchRecognizer = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:#selector(scale:)];
[pinchRecognizer setDelegate:self];
[holderView addGestureRecognizer:pinchRecognizer];
UIRotationGestureRecognizer *rotationRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:#selector(rotate:)];
[rotationRecognizer setDelegate:self];
[holderView addGestureRecognizer:rotationRecognizer];
UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(move:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
[panRecognizer setDelegate:self];
[holderView addGestureRecognizer:panRecognizer];
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tapped:)];
[tapRecognizer setNumberOfTapsRequired:1];
[tapRecognizer setDelegate:self];
[holderView addGestureRecognizer:tapRecognizer];
UILongPressGestureRecognizer *gestureRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(gestureHandler:)];
[holderView addGestureRecognizer:gestureRecognizer];
[holderView.layer setBorderColor: [[UIColor whiteColor] CGColor]];
[holderView.layer setBorderWidth: 3.0];
[self.view addSubview:holderView];
objectDelegate.tagForHolderView+=2;
}

Not sure but as you are doing all the operation UIImagePickerCotroller's delegate methods sometimes it may not work.
I faced same problem while storing the image in document directory & to resolve this i had created new Thread in didFinishPickingMediaWithInfo method & moved entire code in that method. Then after it works fine for me. Try to do that.
