迭代通过单选按钮

Question

有没有办法遍历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)
