Position a UIView relative to the bottom of the parent view?
提问by Camsoft
How can I align a UIView to the bottom of the parent so that the Y coordinate of the frame is relative to the bottom of the screen instead of the top?
如何将 UIView 与父级底部对齐，以便框架的 Y 坐标相对于屏幕底部而不是顶部？
This would be the equivalent to setting the .bottom property in HTML.
这相当于在 HTML 中设置 .bottom 属性。
This is because I want to make sure my view is always at the bottom of window regardless of the height of the parent.
这是因为我想确保无论父级的高度如何，我的视图始终位于窗口的底部。

Once you have initially positioned the view by setting its frameproperty, adjust its autoresizingMaskto include UIViewAutoresizingFlexibleTopMargin. That will keep it anchored to the bottom of its superview.
通过设置其frame属性来初始定位视图后，将其调整autoresizingMask为 include UIViewAutoresizingFlexibleTopMargin。这将使其锚定在其父视图的底部。

You can set the autoresizing mask values on the Sizing pane in XIB or Storyboard editor.
您可以在 XIB 或 Storyboard 编辑器的 Sizing 窗格上设置自动调整大小掩码值。

This should do the trick
这应该可以解决问题
public override void ViewDidLoad()
{
base.ViewDidLoad();
bottomButton.Alignment = UIStackViewAlignment.Bottom;
}
