Answer 1

Try This

am taking Image to move

UIImageView*animationImage;

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panDetected:)];

panRecognizer.delegate = self;

[animationImage addGestureRecognizer:panRecognizer];

In Method You Should Implement Like this

-(void)panDetected:(UIPanGestureRecognizer *)panRecognizer
{

   CGPoint translation = [panRecognizer translationInView:self.view];

   CGPoint imageViewPosition = animationImage.center;
   imageViewPosition.x += translation.x;

   imageViewPosition.y += translation.y;
    
   animationImage.center = imageViewPosition;

   [panRecognizer setTranslation:CGPointZero inView:self.view];
        
}
