Resize the Table cell height as per downloaded image height

Question

I am getting the image\'s URL at run time and I want to download & display these images in a table. Images are going to be download asynchronously. What is more importan

Answer 1

You can make your UIImageView size as per downloading image but it will give bad look.

So i suggest you to make all your image of same size , so it will be look fine and sweet

you can use this to make all your image of same size.

+ (UIImage *)imageScaledToSizeWithImage:(UIImage *)imagewww andsizeee:(CGSize)size
{
    //avoid redundant drawing
    if (CGSizeEqualToSize(imagewww.size, size))
    {
        return imagewww;
    }

    //create drawing context
    UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f);

    //draw
    [imagewww drawInRect:CGRectMake(0.0f, 0.0f, size.width, size.height)];

    //capture resultant image
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    //return image
    return image;
}

But if you really want to show table with different row size then make change your row size on run time

when you will get image then save your image in dictionary with key value is indexPath of row.

[tableImageDict setObject:image forKey:[NSString stringWithFormat:@"%i,%i",indexPath.row,indexPath.section]];

and then reload your table row.

[table reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
                     withRowAnimation:UITableViewRowAnimationNone];

It will change your row height

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIImage *image = (UIImage *)[tableImageDict objectForKey:
                                 [NSString stringWithFormat:@"%i,%i",
                                  indexPath.row,indexPath.section]];


    if (image != nil)
    {
        return image.size.height;
    }
    else{
        return 44.0;
    }
}
