Try this

editButton = [[UIButton alloc]initWithFrame:CGRectMake(width, -4, 30, 30)];
[editButton setImage:[UIImage imageNamed:@"DeleteButton.jpg"] forState:UIControlStateNormal];
[editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside];
editButton.hidden = YES;
[editButton setTag:tag];
[backView addSubview:editButton];


- (void)deleteObjectViewImage:(id)sender
{

    UIButton *button = (UIButton *)sender;
    NSLog(@"Button tag is %d",button.tag);
    button.hidden = YES;
}

For getting Tag Value you have to write this code in Button Click event...

 -(IBAction)deleteObjectViewImage:(id)sender
 {
      UIButton *btn = (UIButton *)sender;
      NSLog(@"%d",btn.tag);
 }

Don't remove colon from 

 [editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside];

[editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside];

expects the function deleteObjectViewImage: to have one argument. But the function definition doesnt has any.

UPDATE:

-(void)deleteObjectViewImage: (id) sender
    {
    UIButton *clickedButton = (UIButton *) sender;
        NSInteger index = clickedButton.tag;
        editButton.hidden = YES;
    }

and use 

[editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside];

Use this line instead of line in your code (colon removed after function name),

 [editButton addTarget:self action:@selector(deleteObjectViewImage) forControlEvents:UIControlEventTouchUpInside];
