Set frame size image inside UITableView - ios

Question

I have an image size : CGRectMake(100,70,50,50) inside cellForRowAtIndexPath. I need to change the frame size image when the cells is odd
Code is:
if(indexPath.row %2)
{
CGRectMake(200,70,50,50)
}
else
{
CGRectMake(100,70,50,50)
}
In the first time when I load TableView, it's work ok, but when I scroll again and again, the frame size image display is in the wrong position. It changes very funny, I don't know why.
Can you help me
Thanks a lot.

Answer 1

You have set set the frame on your UIImageView subview:
if(indexPath.row %2) {
cell.yourImageView.frame = CGRectMake(200,70,50,50)
} else {
cell.yourImageView.frame = CGRectMake(100,70,50,50)
}

Answer 2

You can do it following way.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UIImageView * imageView;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
if(indexpath.row%2 == 0)
imageView = [[UIImageView alloc] initWithFrame:CGRectMake(200, 70, 50, 50)];
else
{
imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 70, 50, 50)];
[cell.contentView addSubview:imageView];
imageView.tag=11;
[imageView release];
}
}
else
{
imageView = (UIImageView*)[cell.contentView viewWithTag:11];
}
// here are couple of other statements
...............
}

Personally, I would create a custom table cell and do something like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ImageCell";
ImageCell *cell = (ImageCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
[cell configureWithRow:indexPath.row];
}
Then in your custom table cell, create an IBOutlet for your resizable image view and add a method:
-(void)configureWithRow:(NSInteger)row
{
if(indexPath.row %2)
{
self.resizableImageView.frame = CGRectMake(200,70,50,50)
}
else
{
cell.resizableImageView.frame = CGRectMake(100,70,50,50)
}
}
This does a couple of things
You don't have to check for a nil cell because you are guaranteed to get a cell back dequeueReusableCellWithIdentifier as long as the identifier matches one in your storyboard and your view controller is a UITableViewController.
You move the logic for the configuration of the cell to the custom table view cell, which is where it really should be. The view controller shouldn't care about the size of the image in the cell.
