注意：1.适配iphone5时要添加一张启动图片，图片命名为Default-568h@2x.png，不然iphone5两边还是黑边。

     2.setDesignResolutionSize()是指设计尺寸，而getWinSize()是窗口尺寸，显示时是把设计尺寸按照设置的填充模式映射到窗口上去。

     3.三种填充模式：kResolutionExactFit（宽高非等比缩放，全填充）、kResolutionNoBorder（宽高等比缩放，部分区域可能被裁减）、kResolutionShowAll（宽高等比缩放，部分区域可能出现黑边），我觉得用kResolutionNoBorder好些。
