iPhone app not working on device - iphone

Question

I have iPhone it works fine on simulator but not on device firstly it was working but now it is not working
Also gives below warning
WARNING: Using legacy cell layout due to delegate implementation of tableView:accessoryTypeForRowWithIndexPath: in <CategoriesList: 0x497b000>. Please remove your implementation of this method and set the cell properties accessoryType and/or editingAccessoryType to move to the new cell layout behavior. This method will no longer be called in a future release.
this is the first view table view of my app
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UIImageView* img = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"cell1.png"]];
[cell setBackgroundView:img];
[img release];
}
UIImage *image = [UIImage imageNamed:#"arrow.png"] ;
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height);
button.frame = frame;
[button setBackgroundImage:image forState:UIControlStateNormal];
[button addTarget:self action:#selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside];
button.backgroundColor = [UIColor clearColor];
cell.accessoryView = button;
Book*aBook=[appDelegate.books objectAtIndex:indexPath.row];
NSString*celltext=aBook.name;
cell.textLabel.textColor=[UIColor blackColor];
cell.textLabel.text=celltext;
cell.textLabel.backgroundColor=[UIColor clearColor];
cell.backgroundColor=[UIColor clearColor];
self.tableView.backgroundColor=[UIColor clearColor];
self.title=aBook.name;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
//cell.textLabel.backgroundColor=[UIColor clearColor];
//UIImage* theImage = [UIImage imageNamed:#"cell1.png"];
//cell.image = theImage;
return cell;
}
- (void)checkButtonTapped:(id)sender event:(id)event
{
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition];
if (indexPath != nil)
{
[self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath];
}
}

Answer 1

you have not told us the reason why its not working? are you getting any error or crash
Related to your warning:
A accessoryTypeForRowWithIndexPath method identified as deprecated has been superseded and may become unsupported in the future.
So you need to use the accessory-view and accessory-type properties (for both normal and editing modes) of the UITableViewCell class when configuring table-view cells.
