iOS导航栏项目图像大小 [英] iOS navigation bar item image size

问题描述

我想自定义我的NavigationBar按钮并使用自己的图像.

I want to customize my NavigationBar button and using my own images.

问题是尺寸应该是多少?

The question is what the size should be?

我发现按钮的尺寸应该是40 * 40，所以视网膜的图像应该是80 * 80?

I found that the button size should be 40*40, so the image should be 80*80 for retina?

推荐答案

这些是

These are the sizes that the documentation recommends for custom icons now.

• @ 2:50 x 50
• @ 3:75 x 75

创建两个以上像素大小的图像，然后将它们添加到Assets.xcassets文件中的新图像集中. (显然，不再需要@ 1大小了.)

Create two images of the above pixel sizes and then add them to a new image set in your Assets.xcassets file. (Apparently the @1 size is no longer needed.)

或者，您可以使用通用矢量图像(pdf)(请参阅).这是我最近的偏好.

Alternatively, you could use a universal vector image (pdf) (see here and here). This has been my preference recently.
