推荐答案

据我了解你的问题是要控制多少图像将在每一个不同的屏幕尺寸增加。您可以控制​​一切。你需要做的就是指定一个相当于你的图像宽度约束。在图像的宽度preferable。的关系将与上海华，然后你可以通过添加自己的乘数变化之间的关系。

As I understood your problem is that you want to control how much the image will be increased in each different screen size. You can control everything. What you need to do is to assign an equals width constraint on your image. Preferable on image's width. The relation will be with the superview and then you can change the relation by adding your own Multiplier.

您需要做的正是：

1）选择您的图像视图。

1) Select your image view.

2）按住Ctrl键。当你拿着它，从图像视图外视图中拖动鼠标。

2) Hold down the control key. While you are holding it, drag your mouse from the image view to the outer view.

3）选择等于宽度。

3) Select 'Equals width'.

4）你的约束双击在约束选项卡。

4) Double click on your constraint in the 'Constraints' tab.

5）确保图像的看法是psented作为第一个项目$ P $，如果不是第一个项目单击，然后选择反向第一和第二个项目。

5) Ensure that the image view is presented as the first item, if not click on the first item and select 'Reverse first and second item'.

6）与乘法器玩，直到你满意的preVIEW屏幕上的结果。

6) Play with the multiplier until you are satisfied with the result on the preview screen.
