Question

i am creating an application which includes dynamic pages. actually, i created some dynamic questions and UIButtons (custom checkBox) by checking the responses from the server.
my code is here,

  NSString *response=[ResponseFromServer ObjectAtIndex:0];


 if ([comSt compare: @"CheckBoxList"]==NSOrderedSame)
            {

                int count=[ResponseFromServer count];

                            for(int i=0;i<count;i++)
                            {


                                button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
                                button.tag=i;
                                [button setFrame:CGRectMake(0.0f, 0.0f, 37, 37)];
                                [button setCenter:CGPointMake(116.0,p1)];
                                [button setImage:[UIImage imageNamed:@"uncheck.png"] forState:UIControlStateNormal];

                                [button setBackgroundColor:[UIColor whiteColor]];
                                [button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
                                [self.scrollView addSubview:button];

                                p1=p1+30;
                            }

-(void)checkButtonTapped:(id)sender
    {

      int tagVal = [(UIButton*)sender tag]; 


         if (tagVal==0) {
              NSLog(@"tag =  0");

             [button setSelected:YES];
             [button setImage:[UIImage imageNamed:@"check.png" forState:UIControlStateSelected];  //not working, button image is not changing 



      }

assume i have created 5 dynamic buttons with different tag. i set the image for all those button to uncheck.png first. it works.
but when i clicked a specific button and need to change that button image to checked.png, its not working on the button action.
i need to change it like checkBox control, how will i access the control of a dynamically created button from a group of buttons?

i think u can understand my requirement, thanks in advance..

While adding dynamic button set [button setSelected:NO];

Replace method and Add one method given below

  -(void)checkButtonTapped:(id)sender
{

  UIButton *curButton = (UIButton*)sender 

  if (curButton.tag==0) 
  {
     [self buttonAction:curButton];
  }

  if (curButton.tag==1) 
  {
      [self buttonAction:curButton];
  }

  // continues
 }


 -(void)buttonAction:(UIButton *)curButton
 {

   if(![curButton isSelected])
     {
       [curButton setSelected:YES];
       [curButton setImage:[UIImage imageNamed:@"check.png" forState:UIControlStateSelected];  //not working, button image is not changing 
     } else {
       [curButton setSelected:NO];
       [curButton setImage:[UIImage imageNamed:@"uncheck.png"] forState:UIControlStateNormal];

     }
 }
