Changing the button image in one section changing the other also? - iphone

Question

I have an application in which i am loading two types cells in a table view from two different custom classes.I have 5 sections in my table view each having single rows.I am added one button to my cell and when clicking on it it will change the image of the button .as button.selected=YES;ike that.But my problem is when i am scrolling the cells r repeating,ie if i selected a button in a row then the background image of that row only need to change.But in my case some cell buttons are also changing.Here is how i am adding the things.`
- (UITableVieCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier1 = #"CellIdentifier";
static NSString *CellIdentifier2 = #"Cell";
if (indexPath.section == 0 && indexPath.row==0)
{
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil)
{
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier1] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:#"dhjkhs.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.datelabel.text=#"skhfkhdf";
cell.nameLabel.text=#"dsdbjsbjf";
cell.msg.text=#"dshjshhshd";
[cell.lbutton addTarget:self action:#selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.myImageView.image=[UIImage imageNamed:#"sdsd.png"];
cell.llabel.text=#"sdjkjskljdls";
cell.llabel.tag=indexPath.section+1;
return cell;
}
else
{
Customcellwithimage *cell = (Customcellwithimage *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil)
{
cell = [[[Customcellwithimage alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier2] autorelease];
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:#"sdsdsd.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.datelabel1.text=#"sdsdsdsd";
cell.nameLabel1.text=#"sdsdsdsdsd";
cell.msg1.text=#"sdsasfkdakfhk ";
[cell.likebutton1 addTarget:self action:#selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.myImageView1.image=[UIImage imageNamed:#"jpg1.png"];
cell.cellview1.image=[UIImage imageNamed:#"adsdsd.png"];
cell.llabel1.text=#"sdsdsdsdl";
cell.llabel1.tag=indexPath.section+2;
cell.bannerview1.image=[UIImage imageNamed:#"dsdsd.png"];
return cell;
}
return Nil;
}
i have 10 sections each returning 1 row.My problem is i need to change the image of the button when clicked.I was adding that button in the customcellwith image class as
[lbutton1 setImage:[UIImage imageNamed:#"sdsd.png"] forState:UIControlStateNormal];
[lbutton1 setImage:[UIImage imageNamed:#"sdsdsd.png"] forState:UIControlStateSelected];
lbutton1.selected=NO;`
and in my code i have added `
UIButton *button = (UIButton *)sender;
button.selected=YES;
` But the problem here is it also changing the button in another section also.Can anybody help me?

Answer 1

Maybe there is some problem with your check condition for if (indexPath.section == 0 && indexPath.row==0). This check will always NO when it's not the first section. So your cell will not be reused for your class CustomCell except for your first section's first row.

I am not sure if I fully understand the problem, but I think you want to move background creation also behind the if. Once it will be changed you should reset it and they way it is now it won't be reseted (just like you reset selection style you should reset background)
if (cell == nil)
{
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier1] autorelease];
}
cell.backgroundView = [ [[UIImageView alloc] initWithImage:[ [UIImage imageNamed:#"dhjkhs.png"] stretchableImageWithLeftCapWidth:0.0 topCapHeight:5.0] ]autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.datelabel.text=#"skhfkhdf";
cell.nameLabel.text=#"dsdbjsbjf";
cell.msg.text=#"dshjshhshd";
[cell.lbutton addTarget:self action:#selector(callAction:) forControlEvents:UIControlEventTouchUpInside];
cell.myImageView.image=[UIImage imageNamed:#"sdsd.png"];
cell.llabel.text=#"sdjkjskljdls";
cell.llabel.tag=indexPath.section+1;
return cell;
