uistoryboard 中水平方向的 stackview 内的控件右对齐

问题描述 投票：0回答：1

我有一个垂直方向的StackView（卡片视图），对齐和分布都是“填充”。

在里面我还有一些水平方向的 StackView 和一些其他控件。其中，最后一个具有水平方向的 StackView，Alignment = Top 和 Distribution = Fill，有两个按钮“保存”和“取消”

最后一个堆栈视图的 XML：

<stackView opaque="NO" contentMode="right" alignment="top" spacing="15" translatesAutoresizingMaskIntoConstraints="NO" id="qk0-Aa-LVy">
<rect key="frame" x="0.0" y="301" width="414" height="51"/>
<subviews>
    <button opaque="NO" contentMode="scaleToFill" contentHorizontalAlignment="center" contentVerticalAlignment="center" buttonType="system" lineBreakMode="wordWrap" translatesAutoresizingMaskIntoConstraints="NO" id="TzA-jj-KRx">
        <rect key="frame" x="0.0" y="0.0" width="199.66666666666666" height="31"/>
        <inset key="contentEdgeInsets" minX="10" minY="10" maxX="10" maxY="10"/>
        <state key="normal" title="Button"/>
        <buttonConfiguration key="configuration" style="plain" title="Save" buttonSize="medium"/>
    </button>
    <button opaque="NO" contentMode="scaleToFill" contentHorizontalAlignment="center" contentVerticalAlignment="center" buttonType="system" lineBreakMode="middleTruncation" translatesAutoresizingMaskIntoConstraints="NO" id="xHU-No-XcV">
        <rect key="frame" x="214.66666666666663" y="0.0" width="199.33333333333337" height="31"/>
        <state key="normal" title="Button"/>
        <buttonConfiguration key="configuration" style="plain" title="Cancel"/>
    </button>
</subviews>
<constraints>
    <constraint firstAttribute="bottomMargin" secondItem="TzA-jj-KRx" secondAttribute="bottom" constant="20" id="d5Z-DX-Keg"/>
</constraints>

我希望两个按钮右对齐，但我不知道如何实现。我使用 Xamarin.iOS。

请注意，可能存在一些不需要的约束和其他代码，因为这是我的第一个学习项目。请让我知道需要更多 xml 行。预先感谢。

如果想让两个按钮右对齐，可以创建一个父UIView，然后在其中分别添加两个子UIView，使两个按钮右对齐。我做了一个小demo，大家可以参考一下：
