Change Cell Image when didselect.

[tjnew]

Hello,
I m trying to find how i could change cell's image with didselect method.

here is my code.

- (UITableViewCell *)tableViewUITableView *)tableView cellForRowAtIndexPathNSIndexPath *)indexPath {

static NSString *MyIdentifier = @"Cell";

cell =((MainCellnew *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier]);
if (cell == nil) {
[[NSBundle mainBundle] loadNibNamed:@"MainCellnew" owner:self options:nil];
}


[cell changeimage:[UIImage imageNamed:@"image_1.png"] ];

return cell;

}

all my cells now have image_1.png and everything is ok.

- (void)tableViewUITableView *)tableView didSelectRowAtIndexPathNSIndexPath *)indexPath {

HERE I WANT TO CHANGE THE IMAGE OF SELECTED IndeXPath.row
[cell changeimage:[UIImage imageNamed:@"image_2.png"]];

next *controller = [[next alloc] initWithNibName:@"next" bundle:nil];

[self.navigationController pushViewController:controller animated:YES];

}

Than you for any help.

Did you try calling cellForRowAtIndexPath? Hopefully that will give you the existing cell if it's not on the screen, and not create a new one. I did not test this, however.

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

Thank you for your help

Then you need to store that data somewhere so that cellForRowAtIndexPath can load the correct image. your cellForRowAtIndexPath always loads image_1.png, right? you need to keep track of which cell is selected so that you can load the right image.

The problem finally solved keeping value (yes,no) for every cell in new nsmutablearray. so everytime i select new cell the value change to yes. and the with if statement i was able to appear the correct image.

thanks

So cellForRowAtIndexPath always loads image 1.
Then you select the cell, and a new image is loaded.
Then you scroll off the screen, and the cell is destroyed (or recycled).
Then you scroll it back onto the screen and a new cell is created with cellForRowAtIndexPath which always loads image 1.

That last step is the broken one - you need to check if the cell being created is for the selected item, and load the right image.
