Hover the mouse over the button, hold down the mouse button, and move the mouse. – PengOne Jun 17 '11 at 22:10

Apple's [Touches sample app](http://developer.apple.com/library/ios/ipad/#samplecode/Touches/Introduction/Intro.html) may help you. – Jun 18 '11 at 01:47

try this u can drag and drop your button what ever you want
implement this code in ViewDidLoad
[self.shoeimageOutlet addTarget:self action:@selector(imageMoved:withEvent:) forControlEvents:UIControlEventTouchDragInside];
[self.shoeimageOutlet addTarget:self action:@selector(imageMoved:withEvent:) forControlEvents:UIControlEventTouchDragOutside];
it will call the method written below
- (IBAction) imageMoved:(id) sender withEvent:(UIEvent *) event
{
CGPoint point = [[[event allTouches] anyObject] locationInView:self.view];
UIControl *control = sender;
control.center = point;
}

There are 3 possibilities nowadays on how to enable items – that is UIViews and UIControls – to be draggable.
- override touchesMoved
- add a target/selector for dragging control events
- add a pan gesture recognizer
