UITableViewCell with UIImageView in a few of them - ios

Question

I have a customized UITableViewCell and I've added a UIImageView to it. The thing is, there are times when I want to remove the UIImageView as the data I receive from the server does not have an image associated with it. How do I make the cell layout change such that the other elements move up. Should I set the UIImageView's frame to zero? Using a placeholder image is not a solution.
Here's what my problem looks like:
The row with index 0 does not have an image but there is a space in between the top and the bottom label. Is there a way I can do this using Auto Layout?

Answer 1

Your problem is actually caused by heightForRowAtIndexPath, you have to return the proper value in this method, something like:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
YourCustomObject *object = [tableDataSource objectAtIndex:indexPath.row];
if(object.hasImage) {
return heightForCellWithImageInside;
}
else {
return heightForCellWithoutImageInside;
}
}
Then, in your cellForRowAtIndexPath just hide the UIImageView if there is no image for it.

You can dynamically change the height of cell.If there is an image,then increase cell height otherwise not.Also set the imageView whenever u get image from server otherwise no need to set imageView.like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"ImageCellItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
if(imageFromserver)
{
//Set your imageView here
}
else
{
// Do nothing
}
return cell;
}

when ever there is no image coming from server hide or remove your image view and assign the frame of image view to your bottom label.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] ;
}
if(yourimage==nil)
{
bottomlabel.frame=imageview.frame; // you can do something like this, as per your need.this is just example
}
return cell;
