通过radiobuttons迭代

Question

有没有办法迭代属于某个组或动画片段的单选按钮？ 像这样：

private var radioButtons:RadioButtonGroup = new RadioButtonGroup("radioButtons");
for (var i:int = 0; i < radioButtons.numRadioButtons; i++ )
{
    trace(radioButtons);
// Here i want to do something like this: radioButtons[i].label = "hello";
}

Answer 1

radioButtons.getRadioButtonAt( i )
