iPhone App: touch event and transfer control to other object

In my iPhone App I want to play with touch events. Here my requirement is as shown in figure:

enter image description here

I am creating Button 2 on the touch drag Exit event of Button 1. Here is the code

 -(IBAction)addView:(id)sender{

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.tag=count;
count++;
    [button addTarget:self action:@selector(imageTouch:withEvent:) forControlEvents:UIControlEventTouchDown];
    [button addTarget:self action:@selector(imageMoved:withEvent:) forControlEvents:UIControlEventTouchDragInside];
    [button addTarget:self action:@selector(imageTouchCancel:withEvent:) forControlEvents:UIControlEventTouchUpInside];

button.frame=CGRectMake(shape1.frame.origin.x-30,shape1.frame.origin.y-40, 100, 100);

   [button setImage:[UIImage imageNamed:imgname] forState:UIControlStateNormal];
   [button addSubview:close];
  [baseview addSubview:button];

 }

Here I am able to create button 2 successfully but the problem is I am not able to drag and move the button2 in single touch events means while dragging outside on button 1 it is creating button 2 but to move button 2 i have to take my finger off the screen and on next touch on button 2 i could move the button 2.

My question is, how to create button2 and move it across screen on single touch cycle?

Set button UserInteraction Disable ands use following code..

[button2 setUserInteractionEnabled:NO];

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
CGPoint location = [touch locationInView:touch.view];
button2.center = location;
}


-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
[self touchesBegan:touches withEvent:event];
 }

Sample code for dragging image over the view

Hope, this will help you
