我做了一个照片库，我使用 Flash cs5 As3 UILoader 组件，如何在中心加载所有不同尺寸的照片？左上角的Uiloader组件注册，需要make to中间吗？舞台宽 1000 像素，高 420 像素。

我的照片大小不一，有的803x400，有的580x400，uiLoader注册点在左上角，就是这个问题，如果我把580x400放在中间，803x400px的手机会在右边很远.

有没有办法解决这个问题？

如果我理解这样做，您必须将 uiloader 安排在其容器的中心：

function completeHandler(event:Event):void
{
var spr = new Sprite();

// Place spr anywhere on the stage
spr.x = stage.stageWidth / 6;
spr.y = stage.stageHeight / 235;
spr.addChild( uiLoader );

addChild( spr );

// Center uiLoader in spr
uiLoader.x =  -  uiLoader.content.width / 2;
uiLoader.y =  -  uiLoader.content.height / 2;
new Tween(spr,"rotationX",Elastic.easeOut,45,0,4,true);
 }
