Find an exact UIImageView on a cell in didSelectRowAtIndexPath - iphone

Question

in my cellForRowAtIndexPath
- (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
//...do cell setup etc.
UIImage *iconthumbNail = [UIImage imageNamed:#"icon.png"];
UIImageView * iconimgView = [[UIImageView alloc] initWithFrame:CGRectMake(265, 34, 25, 25)];
[iconimgView setImage:iconthumbNail];
//imgView.image = thumbNail;
[cell addSubview:iconimgView];
[iconimgView release];
// add a few more UIImageViews to the cell
}
So then in my
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell * theCell = [tableView cellForRowAtIndexPath:indexPath];
for (UIView * b in cell.subviews)
{
if ([b isKindOfClass:[UIImageView class]])
{
// how do I check that its 'iconImgView' so that I can change it?
}
}
So I add an UIImageView in my cellForRowAtIndexPath, then when that table cell is selected I want to change one of the images in the cell, 'iconImgView' but how do I identify this UIImageView from the other UIImageViews present in that cell?
Many Thanks,
-Code

Answer 1

Instead of using that approach, I would assign a tag to the UIImageView you are looking for.
iconimgView.tag = 1;
Then in the didSelectRowAtIndexPath method, use this:
UIImageView *iconimgView = (UIImageView *)[cell viewWithTag:1];
If you still want to do it your way, you can do like this:
if ([b isKindOfClass:[UIImageView class]]) {
UIImageView *myView = (UIImageView *)b;
if ([b.image isEqual:[UIImage imageNamed:#"yourImageName"]]) {
// Do your stuff
}
}

If your only goal is to change the image of the selected cell, this can be done more efficiently. All you have to do is read/write to the cells imageView property.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *theCell = [tableView cellForRowAtIndexPath:indexPath];
[[theCell imageView] setImage:[UIImage imageNamed:#"someImage.jpg"]];//altering the existing image
UIImageView *myImageView = theCell.imageView;//read the image property of the cell
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
