Question

My tableview cells (TTTAbleViewCells) cells contain images that are loaded from the internet aynchronously.When the image is loaded the the table view cell gets a callback from the TTImageView object.

Question is at the point of the callback how can i ask the parent TTTableView to change the height of the cells and resize accordingly.

It seems like the call to heightForRowAtIndexPath is only at the beginning of tableview drawing.

Answer 1

I guess I will answer my own question here.

- (void)imageView:(TTImageView*)imageView didLoadImage:(UIImage*)image
{
    [self setNeedsLayout];
    NSIndexPath *indexPath = [(UITableView *)self.superview indexPathForCell:self];
    if(indexPath!=nil)
    {   
        NSArray* path = [NSArray arrayWithObject:indexPath];
        [(UITableView*)[self superview] reloadRowsAtIndexPaths:path withRowAnimation:UITableViewRowAnimationNone];
    }   
}
