The animation is working in simulator but its crashing on device

Question

Hi...im new to Animation Programming.... My app is crashing in device but its working fine in the simulator... if i keep on dragging on device for few minutes..its crashing.... Can anybody help me please... The following is my code...

//  HomeViewController.m

#import "HomeViewController.h"

@implementation HomeViewController

@synthesize dustImage, myAnimatedView;

float ver_X, ver_Y;

BOOL rotated;

NSTimer *dtimer;

- (void)viewDidLoad {


 [super viewDidLoad];

  self.view.frame  = [[UIScreen mainScreen] bounds];

 }
 else 

#endif

 {
  self.view.frame = [self.view bounds];

 }  
}

 float a, aa;

  UITouch* touch = [[touches allObjects] objectAtIndex:i];

  CGPoint location = [touch locationInView:dustImage];
