了解如何使用情节提要设置启动屏幕.

所以我的问题是如何将图像设置为情节提要的背景，而不希望背景颜色.

so my question is how can i set image as background to storyboard dont want background colour.

我需要图像作为背景，可以在上面放置徽标图像和标签.

i need image as background on which i can put logo image and label.

那有可能吗?如果是，那怎么可能.

推荐答案

您需要在imageView上设置top,bottom,leading,trailing约束.

You need to set top,bottom,leading,trailing constraints on the imageView.

1. 选择Constraint edit mode，然后单击两次以显示侧面上可以拖动以设置约束的点.

1. Select Constraint edit mode ,and click twice to show the point on side which ca be dragged to set the constraint.

将约束值修改为0(在属性"菜单中).

Modify the constraint value to 0(in Property menu).

对这四个约束进行相同的工作.

Do the same work on the four constraints.
