如何在Xamarin iOS中将所有屏幕尺寸的元素居中对齐？
[英]How to align an element in the center in Xamarin iOS for all screen sizes?
问题描述
I have been trying to keep a logo in the center on the screen for all apple screen sizes but it just doesn't seem to work when the logo is small. 
我一直在尝试将徽标放置在所有苹果屏幕尺寸的屏幕中央，但是当徽标较小时，它似乎不起作用。 As I understand , its probably because the left, right, top, bottom margin constrains are absolute and not relative. 据我了解，这可能是因为左，右，上，下边距限制是绝对的而不是相对的。

As @ Sami Kuhmonen mentioned, Add a constraint for center instead. 正如@ Sami Kuhmonen所述，请为center添加一个约束。
How to add? 如何添加？
Drag the pin(locate in the center) to the vertical and horizontal line. 将图钉（位于中心）拖到垂直线和水平线。
