UIDevice *device = [UIDevice currentDevice];
NSString *uniqueIdentifier = [device uniqueIdentifier];

is correct.

my css is:
up-skin: ClassReference(“Style.Skins.Button”);
over-skin: ClassReference(“Style.Skins.Button”);
down-skin: ClassReference(“Style.Skins.Button”);
outBorderColors: #00b4ff, #00b4ff;
inBorderColors: #7f9ca2, #0b99b3;
cornerRadius: 3;
upFillAlphas: 1,1,1,1;
upFillColors: #7f9ca2, #195a6e, #0a7a98, #0b99b3;
overFillColors: #0c5466, #0c5466, #0c5466, #0c5466;
downFillColors: #6d9095, #0f4558, #096785, #0b99b3;

override class is
package Style.Skins
{
import flash.display.GradientType;
import mx.skins.halo.ButtonSkin;
public class Button extends ButtonSkin
{
public function Button()
{
super();
}
protected override function updateDisplayList(width:Number, height:Number):void
{
super.updateDisplayList(width, height);

// берем необходимые свойства из CSS
var outBorderColors:Array = getStyle(“outBorderColors”);
var inBorderColors:Array = getStyle(“inBorderColors”);
var cornerRadius:Number = getStyle(“cornerRadius”);
var upFillAlphas:Array = getStyle(“upFillAlphas”);
var upFillColors:Array = getStyle(“upFillColors”);
var overFillColors:Array = getStyle(“overFillColors”);
var downFillColors:Array = getStyle(“downFillColors”);

var cr:Number = Math.max(0, cornerRadius);
var cr1:Number = Math.max(0, cornerRadius – 1);
var cr2:Number = Math.max(0, cornerRadius – 2);

graphics.clear();

drawRoundRect(
0, 0, width, height, cr,
outBorderColors, [1, 1],
verticalGradientMatrix(0, 0, width, height),
GradientType.LINEAR, [0, 255]);

drawRoundRect(
1, 1, width – 2, height – 2, cr1,
inBorderColors, [1, 1],
verticalGradientMatrix(0, 0, width, height),
GradientType.LINEAR, [0, 255]);

switch (name)
{
case “upSkin”:
{
drawRoundRect(
2, 2, width – 4, height – 4, cr2,
upFillColors, upFillAlphas,
verticalGradientMatrix(0, 0, width – 2, height – 2),
GradientType.LINEAR, null);
break;
}

case “overSkin”:
{
drawRoundRect(
2, 2, width – 4, height – 4, cr2,
overFillColors, upFillAlphas,
verticalGradientMatrix(0, 0, width – 2, height – 2),
GradientType.LINEAR, null);
break;
}
case “downSkin”:
{
drawRoundRect(
2, 2, width – 4, height – 4, cr2,
downFillColors, upFillAlphas,
verticalGradientMatrix(0, 0, width – 2, height – 2),
GradientType.LINEAR, null);
break;
}
}
}
}
}

… but in a flex application I can’t get the same result
