Make your own UITableViewCell subclass. Create and add the button to the cell's contentView in your init method, or create and add it lazily via an accessor property. Override layoutSubviews and postion the button as desired.

Something like this:

@implementation MyCustomCell

- (void) init
{
    self = [super initWithStyle: UITableViewCellStyleDefault reuseIdentifier: nil];
    if ( self != nil )  
    {
         _myButton = [[UIButton buttonWithType: UIButtonTypeRoundedRect] retain];
         [self.contentView addSubview: _myButton];
    }

    return self;
}

- (void) layoutSubviews
{
    [super layoutSubviews];

    // dynamic layout logic:
    if ( ... )
    {

         _myButton.frame = CGRectMake( 10, 10, 100, 30 );
    }
    else 
   {
         _myButton.frame = CGRectMake( 20, 10, 50, 30 );

   }
}

Alternatively, you can attempt to do cell layout in - (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
