UITextField textAlignment Center

Question

这是我的代码，我想将字体大小更改为视图宽度，我正在改变，但对齐失真。

func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool
{
    inputText.contentVerticalAlignment = UIControlContentVerticalAlignment.Center
    inputText.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Center
    inputText.textAlignment = NSTextAlignment.Center
    inputText.adjustsFontSizeToFitWidth = true

    return true
}
