故事板Xcode 10，iOS中的自动布局16:9动画GIF [英] Autolayout 16:9 animated GIF in Storyboard Xcode 10, iOS

问题描述

我正在使用通用应用，并想添加一些教程.为此，我创建了16:9动画GIF.我想将其放置在顶部/左侧或顶部/右侧.文本和按钮，无论剩余空间如何.

I'm having a Universal app and wanted to add a little tutorial. For that I have created a 16:9 animated GIF. I wanted to position that top/left or top/right. Text and buttons wherever space is left.

图像最初为400x225，但只要保留16:9，我就可以接受任何大小.

The image is initially 400x225, but I can accept any size, as long as 16:9 is kept.

我不知道该如何对齐，以便在手机上使用比iPad上小的矩形.

I cannot figure out, how I could align that so that on phones it uses a smaller rect as on an iPad.

推荐答案

如果我理解正确，则希望UIImageView保持相同的比例.

If I understand correctly, you want the UIImageView to keep the same ratio.

您可以使用约束来做到这一点，这是您应该使用情节提要来实现的方式

You can do it using constraints, here’s how you should do it using your storyboard

如果您想将其粘贴到左上/右上角，还应该在superview的顶部添加一个约束-以便将其粘贴到顶部，并使用前导/尾随将其粘贴到左侧/对

If you want to stick it to the top left/right corner you should also add a constraint to the top of the superview- in order to stick it to the top, and a leading/trailing one to stick it to the left/right
