Drag and Drop Image from UITableviewCell to other View

I am working on a iPhone app, where I need to drag an image from UITableViewCell
and drop it in some other UIView outside the tableview.

(imageview added as :[cell.contentView addSubview:imageView]).

Please help me on this, any useful hint , sample code ?? Touch event delegates are not triggering since i am adding UIImageView to UITableViewCell.

You will not get much event in UIImageView so use UIButton and try something like this to drag:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self action:@selector(imageTouch:withEvent:) forControlEvents:UIControlEventTouchDown];
[button addTarget:self action:@selector(imageMoved:withEvent:) forControlEvents:UIControlEventTouchDragInside];
[button setImage:[UIImage imageNamed:@"vehicle.png"] forState:UIControlStateNormal];
[self.view addSubview:button];

- (IBAction) imageMoved:(id) sender withEvent:(UIEvent *) event
{
    CGPoint point = [[[event allTouches] anyObject] locationInView:self.view];
    UIControl *control = sender;
    control.center = point;
}

when your center point match to other UIView use [UIView adSubview:] method to add UIButton in UIView

I have take this code from Basic Drag and Drop in iOS

Have a look at : Drag an Image within the Bounds of Superview
